RYANAIR has warned that consistent technical failures could result in chaos for families heading on holiday this summer.

This comes after an issue earlier this week that caused hundreds of flights to be delayed by up to three hours.

A disruption to UK air traffic control (ATC) involving the Met Office caused earlier this week caused huge issues for airlines.

A technical fault at the Met Office meant that National Air Traffic Services (NATS) were unable to access weather data – so planes were not safely able to take off.

The issue delayed 155 Ryanair flights and impacted almost 30,000 of its passengers.

On July 7, Ryanair reported delays of up to three hours.

easyJet also experienced disruption too with 253 of its flights delayed.

Ryanair has now accused NATS of repeatedly failing passengers and has warned of further delays if it continues.

Ryanair Chief Operations Officer, Neal McMahon said: “Nearly three years after NATS’ catastrophic 2023 system meltdown, UK passengers are once again being delayed because NATS’ systems have failed.”

“The most astonishing part is that NATS continues to charge airlines and passengers more every year while delivering a worse service.”

He added: “UK passengers deserve better. Airlines deserve better. NATS’ staff deserve better.”

As a result, Ryanair has called on NATS CEO, Martin Rolfe, to resign.

A NATS spokesperson told Sun Travel: “A Met Office technical issue overnight on 6/7 July meant that we were not receiving vital weather information into our NATS systems for a short period of time.

“Accurate weather information is vital for air traffic controllers and pilots in managing flights safely. As a result, some air traffic restrictions were put in place and removed soon after.

“We continue to work with the Met Office who are working to fully resolve the problem.”

A Met Office spokesperson added: “An issue we had which temporarily delayed delivery of some of our data is now remedied.

“We know customers rely on our data and we’re sorry for the disruption this caused.”

The United States is about to celebrate its 250th birthday, but as millions across the country prepare to gather this weekend for parades, concerts and festivals, an intense heat wave has settled over much of the eastern US.

Officials across the region are warning that the extreme heat could pose serious health risks over the Fourth of July weekend.

Here’s what you need to know about how the weather will affect the celebrations.

What is America’s 250th anniversary?

It has been 250 years since the United States adopted the Declaration of Independence on July 4, 1776. Unlike a typical Independence Day, this year’s celebrations are unfolding on a much bigger scale, capping years of preparation and planning.

Landing in the midst of a highly polarised moment in American politics, planning for the anniversary has also been contentious.

A decade ago, Congress tasked a bipartisan commission known as America250 with organising the celebrations.

But last year, US President Donald Trump issued an executive order to put his own “Freedom 250” planning committee in charge of many of the anniversary’s marquee events, including the Great American State Fair on the National Mall.

Initially, a variety of musicians were announced as performers for the fair, including country singer Martina McBride, the soul group The Commodores and the pop duo Milli Vanilli. But many withdrew in late May and early June over concerns over the fair’s affiliation with Trump.

Last week, in lieu of the performers, the US president delivered a speech to open the fair, billing himself as the “Number One Attraction anywhere in the World”.

He has also promised to mark the July 4 holiday in Washington, DC, with “the most spectacular TRUMP RALLY of them all”.

What will celebrations look like across the country?

Among thousands of smaller, locally organised celebrations nationwide — including historical reenactments, picnics, concerts and fireworks displays — some of the highest-profile events include:

• Washington, DC: Hundreds of thousands are expected to arrive in the city, where the Great American State Fair will be held along the National Mall, the 2.5 km (1.5 mile) promenade linking the US Capitol to the Washington Monument. It will feature state pavilions, food, live music and a Ferris wheel. Trump has also promised “the largest fireworks show in history.” Around one million people attended the fireworks display for the US’s bicentennial anniversary in 1976.
• Los Angeles: As part of its America’s Block Party event, America250 will hold a benefit concert hosted by Queen Latifah, featuring artists such as Chris Stapleton, Maren Morris and the Smashing Pumpkins.
• Philadelphia: The city where the Declaration of Independence was signed is hosting one of the country’s biggest commemorations, including the burial of a 400kg (900 pounds) time capsule, containing artefacts from across the country, meant to be opened at the next semiquincentennial in 250 years.
• New York: More than 40 tall ships are expected to sail into New York Harbour with almost 20,000 sailors aboard, while more than 200 aircraft fly overhead.
• Boston: Celebrations will include the annual Boston Pops Fireworks Spectacular — a free concert followed by a fireworks display — and a public reading of the Declaration of Independence from the balcony where it was first read aloud to Bostonians in 1776.

How will the heat affect celebrations?

Some celebrations are already being disrupted, with organisers forced to adapt to extreme heat.

On Friday, the Great American State Fair temporarily closed as temperatures reached over 39 degrees Celsius (102 degrees Fahrenheit) in parts of Washington, DC.

But the capital was not the only area affected by the extreme heat.

In Philadelphia, for example, officials announced that the Salute to Independence Semiquincentennial Parade was cancelled, after initially planning to shorten the route to mitigate heat-related risks.

A celebration in Pennsylvania’s Lower Windsor Township was also rescheduled for July 8, while in nearby Norristown, officials cancelled another parade, citing safety concerns.

The heat is also affecting transportation. Amtrak announced several train cancellations in the northeast region and warned that other trains could face delays due to high temperatures, which can affect railway infrastructure.

“Extreme heat can cause rail, bridge and overhead wires to expand,” it said in a statement on Thursday. “As a precaution, Amtrak may enact heat restrictions, which can require locomotive engineers to operate trains at lower speeds, resulting in potential delays.”

What will it actually feel like outside?

While air temperatures in cities such as Philadelphia and Boston are expected to reach around 38 degrees Celsius (100 degrees Fahrenheit), high humidity can make it feel significantly hotter.

That’s because humidity makes it harder for sweat to evaporate and cool the body. Weather agencies use the heat index, often called the “feels like” temperature, to estimate what people will actually be experiencing.

Experts also warn that cities can become even hotter than forecasts suggest as concrete, asphalt and steel absorb heat.

“The number on your phone may actually not reflect the true temperature profile that you’re going out into,” Vijay Limaye, a climate scientist at the Natural Resources Defense Council, told The Associated Press.

What precautions are officials taking?

Aside from changing or cancelling some Fourth of July events, cities across the eastern United States are rolling out broader measures to help people cope with the heat.

In New York City, for example, more than 200 teams of government workers and volunteers are checking on homeless residents and directing people to hundreds of cooling centres, including public buildings, mobile cooling vans and outdoor sites equipped with misting fans.

Mayor Zohran Mamdani urged people to stay inside and avoid “extraordinary temperatures”. He also asked residents to set their air conditioners to 26 degrees Celsius (78 Fahrenheit) to avoid straining the power grid.

Boston is offering residents free admission to several air-conditioned museums, while Providence, Rhode Island, has extended hours at public pools and water parks.

How can people stay safe?

The National Weather Service (NWS) recommends drinking a lot of water, even if you don’t feel thirsty, especially if you’re spending an extended amount of time outside and taking hourly breaks in shade or air conditioning.

Health authorities also urge people to occasionally check in on seniors and other vulnerable populations.

Alcohol can make dehydration worse, so experts also recommend limiting drinking during long outdoor events.

Signs of heat illness include cramping, rapid pulse, heavy sweating, hot red skin, dizziness, confusion, nausea and vomiting, according to the NWS. If you see any of those warning signs, seek medical attention immediately.

Travel could be about to get faster for some families this summer at dozens of UK airports

Families are being reminded that a major change to a key rule across more than a dozen UK airports will come into effect this summer. From next week, on July 8, a security rule will be eased for certain primary school-age children.

Back in May, the UK Government announced that up to 1.5 million more children would soon be able to use UK eGates, helping to speed up the process for them and their families during the summer holidays. Children aged eight and nine, who are at least 120cm (3ft 11in) tall and travelling with an adult, will become eligible under the new measures that come into force on Wednesday, July 8.

Officials say the change to the age threshold will be a welcome relief for families returning home from their holidays with young children in tow. The government claims that passing through an eGate typically takes just a matter of minutes.

With greater numbers of passengers making use of eGates, waiting times at passport control are also anticipated to fall. Prior to 8 July, eGates were generally available to those aged 10 and above, though children under 17 were required to (and must still be) accompanied by an adult, reports the Express.

Passengers are eligible to use an eGate if they have a biometric symbol on the front cover of their passport and are either:

• a British citizen
• a national of an EU country, Australia, Canada, Iceland, Japan, Liechtenstein, New Zealand, Norway, Singapore, South Korea, Switzerland or the USA
• a member of the Registered Traveller Service

Minister for Migration and Citizenship, Mike Tapp said: “Travel with young children can be stressful for parents. By expanding eGate access, more families can experience a swifter and smoother journey home – freeing up precious time this summer holiday season. We are delivering continued improvement to the passenger experience, while keeping our borders safe and secure.”

Border Force Director General, Phil Douglas said: “eGates are an essential part of keeping our border secure. Expanding access for families will deliver safe, smooth journeys whilst freeing up highly-skilled officers to focus on intercepting those who pose a threat to the UK.”

Karen Dee, Chief executive of AirportsUK, the trade body for UK airports, said: “This is a welcome development as it will give more families the ability to take advantage of this technology, speeding up the border process and reducing waiting times for many. Airports work very hard with border authorities to ensure the UK’s front door is both secure and welcoming, with those coming home and visiting enjoying a smooth experience.”

The UK first introduced ePassport gates at airports in 2008, with the very first gate going live at Manchester Airport. Initially, the automated gates were limited to UK, EU, and Swiss citizens but have since expanded to include eligible travellers from dozens of countries, including the US, Canada, Australia, and New Zealand.

2. London Gatwick
3. London Stansted
4. London Luton
5. London City
6. Manchester

ATLANTA — President Trump has tried many ways to tighten his grip on U.S. elections, from signing executive orders to pushing restrictive legislation in Congress. Monday’s Supreme Court ruling siding with states that accept late-arriving mail ballots was the latest example showing the limits of his reach.

It followed back-to-back rulings last week that barred his two sweeping executive orders seeking to change national election rules, more court rulings preventing his Department of Justice from obtaining detailed state voter data and his stalled attempts to get the Senate to pass the SAVE Act. That measure would eliminate nearly all absentee voting, require citizenship documents to register to vote and impose photo identification requirements nationwide right before the midterm elections.

“It’s been a mixed bag for Republicans,” said University of Notre Dame law professor Derek Muller. But the president, he added, “has come up mostly empty-handed.”

Trump’s efforts have not been entirely fruitless. Republican-run states have satisfied his demands to redraw congressional district lines, efforts buoyed by the Supreme Court striking down a key section of the Voting Rights Act, and he has been directing his Department of Justice to investigate voting and election operations, which Democrats see as a possible prelude to their involvement in November.

All the activity around how the nation votes and runs its elections is a reflection of the Republican president’s long fixation on his false claim that his 2020 election defeat was rigged. He has been so frustrated by the inability of the Senate to pass the SAVE Act that he has refused to sign a bipartisan housing bill.

He weighed in again Monday after the Supreme Court’s decision in the mail ballot deadline case, saying on his social media account that he is trying to “save America from crooked elections.” Voting rights groups and Democrats see him abusing power and attempting to suppress legal voters to gain an advantage in the midterms, when control of Congress is at stake.

Regardless, Muller said Trump faces legal and political realities: The Constitution gives the states and Congress authority over elections while providing no such role for the president.

“That’s how federalism works,” Muller said.

Here’s a look at Trump’s efforts to reshape election rules and what options he might have left for the November midterms.

Focus on noncitizens and voter data has met roadblocks

The president has repeatedly said U.S. elections are riddled with fraud in part because of noncitizen voting. Research shows the problem to be rare, accounting for a minuscule percentage of fraud cases. Convictions are measured in the hundreds over periods in which tens of millions of ballots are cast.

Trump’s view resulted in a multiagency push to nationalize voter data and use federal resources to help states remove voters from the rolls. The Department of Justice has sought detailed voter files from multiple states, data that would include dates of birth and partial Social Security numbers. Democratic and some Republican secretaries of state balked, and federal lawsuits followed. The administration has lost every case so far.

Homeland Security citizenship check rejected in court

Trump’s Department of Homeland Security, with help from the DOGE effort led by Elon Musk, revamped a government tool called SAVE (Systematic Alien Verification for Entitlements). The program has been a key pillar of his efforts to cull potentially ineligible voters from state rolls.

Last week, a federal judge blocked its use as a mass citizenship check.

The administration, according to its own news releases, had allowed local election administrators to search users by the thousands, using a wider range of metrics rather than DHS-issued identification numbers. At least 67 million registrations, primarily in Republican-controlled states, were analyzed. Tens of thousands were flagged as potential noncitizens or people who have died, but some voters were wrongly identified as ineligible.

U.S. District Court Judge Sparkle L. Sooknanan ruled that Trump’s changes aggregated Americans’ sensitive personal data in a way that could result in voters being wrongly purged from the rolls.

“All in all, the federal government has knowingly trampled on the privacy rights of American citizens in a manner that threatens the sacred right to vote,” Sooknanan said in her order.

Executive orders used in place of legislation

As presidents before him, Trump signed executive orders when Congress would not enact his policy preferences.

Trump’s first order reflected his emphasis on noncitizens. Like the SAVE Act pending on Capitol Hill, it sought to require would-be voters to document their citizenship to be able to register to vote.

U.S. District Court Judge Denise Casper put a temporary block on the order last year as she considered the case and last week made her decision permanent. The Constitution, Casper wrote, “does not grant the President any specific powers over elections.”

Trump issued a second order in March, as the SAVE Act’s rough path in Congress became obvious. He called for a national voter list using data from U.S. Citizenship and Immigration Services and the Social Security Administration. Further, the order would have empowered the U.S. Postal Service to determine who gets an absentee ballot and threatened local elections officials with prosecution.

Absentee voting is a staple of U.S. elections, but Trump describes the practice, incorrectly, as allowing fraud — even as he has used it himself. A 2025 report by the Brookings Institution found that mail voting fraud occurred in only 0.000043% of total mail ballots cast.

Democratic secretaries of state sued, and U.S. District Court Judge Indira Talwani made the same legal assessment as Casper. The provisions, she wrote last week, “unconstitutionally violate the separation of powers.”

The White House has indicated it will appeal.

Even Trump says the SAVE Act has long odds

Trump on Monday called the Senate logjam “crazy” and one of the holdouts, Republican Alaska Sen. Lisa Murkowski, “Trump-deranged.”

It’s the latest legislative tussle that prompted Trump to demand Republicans scrap the filibuster, which requires most major legislation to get support from 60 of the 100 senators. But that likely wouldn’t matter in this case, with four of the Senate’s 53 Republicans declaring their opposition to the bill itself: Murkowski, Susan Collins of Maine, Mitch McConnell of Kentucky and Thom Tillis of North Carolina.

The president acknowledged Monday that the SAVE Act is “probably not going to happen.”

Trump still has options for the November elections

Both major parties have national operations to monitor elections, including legal teams ready to file challenges.

Despite the Republican National Committee losing the mail ballot case, Chairman Joe Gruters on Monday alluded to those efforts: “We are not going to be deterred by this decision, and the RNC will keep fighting to have elections end on Election Day,” he said.

Meanwhile, Trump has been developing a possible roadmap for more aggressive actions.

His U.S. attorney in Los Angeles said in June that he had opened multiple election fraud investigations, and he sent a prosecutor to the county’s vote-tabulation center after California’s June primary. Six months earlier, FBI agents executed a warrant and seized ballots and other records from the 2020 election in Georgia’s Fulton County, which includes Atlanta.

Muller, the law professor, said local elections officials “already are having conversations about chain of custody disputes” for ballots as they are cast, collected, counted and stored.

He and UCLA law professor Rick Hasen noted that judicial warrants are required for the kinds of actions that happened in Fulton County. Muller predicted “the bar would be even higher” for any warrant the administration requests during a live election.

Hasen added that he’s working to educate judges around the country on the importance of chain of custody for ballots.

“Republicans believe him when he says the election is rigged. And then when Republicans try to change voting rules to tighten things up, that causes Democrats to also think that the election system is being rigged,” Hasen said. “So, if what he’s trying to achieve is undermine voters’ confidence in the election process, he seems to have succeeded spectacularly.”

Sweaty, shirtless football players lying on the pitch have seldom raised eyebrows as they did last week when photographs of European players struggling to train in the heat sparked concerns over sweltering US summer temperatures at the World Cup.

Scientists have long cautioned that extreme heat could disrupt sporting events. Last month, climate experts warned that one in four World Cup games could be played in very hot conditions, affecting fans and players alike.

Those warnings materialised last week; social media was abuzz with sunburnt players — mostly from European teams used to cooler climates — dousing themselves with water to cool off. Norway’s team even opted to wear ice collars around their necks during the friendly against Morocco.

But England captain Harry Kane quickly dismissed speculation over how much the heat would affect players, saying it “won’t be a factor”, thanks to his team’s World Cup training regimen.

So, how much will higher temperatures actually affect players at the World Cup? Al Jazeera takes a look.

What have experts said about heat during World Cup matches?

Th 2026 World Cup could be the hottest on record since the tournament began in 1930 due to a sharp rise in global temperatures, explained Al Jazeera weather presenter Everton Fox.

“Around half a dozen of the venues are prone to extreme heat; places like Dallas, Houston, Miami and the Mexican venues are all likely to swelter,” Fox said.

Daytime temperatures there are expected to average 28C, though the stadiums in Dallas, Houston and Atlanta have air conditioning.

Approximately 26 of the 104 matches could reach at least 26C in the Wet Bulb Globe Temperature (WBGT) index — which measures how effectively the body can cool itself — while five games are expected to be played in conditions of 28C WB or higher, according to World Weather Attribution (WWA), a network of climate scientists.

Of those 26 matches, 17 will be played in stadiums with cooling systems, reducing risks for players and fans.

But more than a third of the games with a one in 10 chance of exceeding 26C will be in venues without air conditioning.

How do hotter temperatures impact athletes’ performance?

Heat stress due to increased humidity, exposure to solar radiation and the effects of wind speed will impact players running around in direct sunlight, Fox said.

“All this makes it harder for the body to cool down as it becomes harder for sweat to evaporate as quickly,” said Fox, a senior meteorologist with more than 30 years of experience.

Physical performance coach Raiyan Abbasi explained that, although the body sweats to achieve thermoregulation – a process that allows the body to maintain its core internal temperature – excessive sweating due to heat could lead to dehydration, cramps and increased fatigue.

Are athletes used to such high temperatures?

“Yes, the majority of athletes will know how to deal with this kind of heat since they’re elite players training and competing in various conditions,” said Abbasi, who has worked as a physical performance coach for British clubs Swansea and West Ham, as well as the Pakistan national side.

Teams will have a performance coach and medical staff to make sure players are ready for the tournament, including through acclimatisation, Abbasi explained – echoing what Kane said over the weekend after his side beat New Zealand 1-0 in Tampa, Florida, where temperatures soared beyond 30C.

Do athletes from hotter nations have an advantage?

World Cup nations whose players train in hotter climates may have a slight advantage when it comes to adjusting to high temperatures in the US.

“But essentially, countries that prepare and perform well can minimise that difference,” Abbasi said, adding that heat can be used positively too.

“Heat is a significant factor in creating good athletes; one way to improve athletic capabilities is to train in the heat.

“It can make big adaptations in your body to improve body temperature.”

Could the World Cup have been held before or after summer in the US?

Fox noted that international tournaments are traditionally in the European domestic off season, which is when the 2026 World Cup is being held.

“Ideally, US weather is most conducive in the spring and autumn, but you’d then be looking at the tornado season in spring and hurricane late summer through autumn before you even begin to think about their domestic sports which locals have more interest in,” Fox said.

What measures has FIFA taken for players and fans?

FIFA said it has carried out heat-risk planning, with measures including three-minute hydration breaks in each half of games, cooling infrastructure for fans and players, adapted work-rest cycles, and enhanced medical readiness that scale according to real-time conditions.

“The hydration breaks probably need to be longer to gain full benefit, but then you risk turning it into a game of four quarters,” Fox said jokingly, although he argued that FIFA could have confined games to northern parts of the US and Canada.

FIFA has also delayed kickoff times for some matches to start outside the hottest afternoon hours.

STRIKES across Portugal are set to go ahead tomorrow causing widespread disruption across the country.

Rail workers, cabin crew and public transport staff are all staging a walkout.

At its airports in Portugal, strike action is predicted to affect hundreds of flights with 500 at risk of being cancelled and delayed.

Over half of these flights are operated by TAP Air Portugal, as well as other Portugália and SATA services.

On social media, TAP Air Portugal said it would still operate a minimum of 79, it is also rebooking travel options for affected passengers.

The airline Air Europa has cancelled all of its flights between Madrid and Lisbon and Porto.

The union added that easyJet and Ryanair flights are also expected to be impacted.

easyJet told Sun Travel: “Due to a national strike in Portugal on 3 June, like all airlines operating to and from the country we can expect some disruption to our flying programme. 

“We will be doing all we can to minimise the impact of the strike action and will contact customers directly with their options if their flights are affected.

“While this is outside of our control we are sorry for any inconvenience this strike action may cause.”

Ryanair however told The Independent that it did not expect any disruption and would operate as normal.

Away from airports, staff working for FECTRANS are expected to walkout.

This is expected to limit service on the Lisbon Metro and will disrupt those with travel plans across the city.

Union members include those working on the Porto Metro, so Porto is another city set to be majorly affected by the strike action.

Due to the sheer volume of staff strikes, it’s thought that the delays could impact travel on the following days, too.

Flight compensation rules

A look at your rights if a flight is delayed or cancelled, when your entitled to compensation and if your travel insurance can cover the costs.

What are my rights if my flight is cancelled or delayed?

Under UK law, airlines have to provide compensation if your flight arrives at its destination more than three hours late.

If you’re flying to or from the UK, your airline must let you choose a refund or an alternative flight.

You will be able to get your money back for the part of your ticket that you haven’t used yet.

So if you booked a return flight and the outbound leg is cancelled, you can get the full cost of the return ticket refunded.

But if travelling is essential, then your airline has to find you an alternative flight. This could even be with another airline.

When am I not entitled to compensation?

The airline doesn’t have to give you a refund if the flight was cancelled due to reasons beyond their control, such as extreme weather.

Disruptions caused by things like extreme weather, airport or air traffic control employee strikes or other ‘extraordinary circumstances’ are not eligible for compensation.

Some airlines may stretch the definition of “extraordinary circumstances” but you can challenge them through the aviation regulator the Civil Aviation Authority (CAA).

Will my insurance cover me if my flight is cancelled?

If you can’t claim compensation directly through the airline, your travel insurance may refund you.

Policies vary so you should check the small print, but a delay of eight to 12 hours will normally mean you qualify for some money from your insurer.

Remember to get written confirmation of your delay from the airport as your insurer will need proof.

If your flight is cancelled entirely, you’re unlikely to be covered by your insurance.

There are six host cities (Miami, Houston, Dallas, Monterrey, Kansas City and Atlanta) where the WBGT could feasibly reach at least 32C (90F) during the afternoon which would be considered as extreme heat stress where the body really struggles to keep itself cool.

To reduce these risks, matches are generally scheduled outside the hottest part of the day, with many kick-offs taking place in the late afternoon or evening. Scotland’s group C game against Brazil in Miami, for example, will have a kick-off time of 18:00 ET (23:00 BST).

Some venues, including stadiums in Houston and Dallas, also have retractable roofs and climate control to moderate conditions.

Summer heatwaves are also a common occurrence in North America and Mexico where temperatures can rise 10C (50F) or more above average, potentially pushing conditions into much more challenging territory for both players and fans.

In New York for example, the location of this year’s World Cup final on 19 July at 15:00 ET (20:00 BST), a typical heatwave could result in air temperatures in the mid-30sC (mid 90F) and WBGT of around 30C (86F) leading to extreme heat stress.
