flights

OFFICIALS have warned that there is just weeks of jet fuel supplies left before airlines start running out.

Earlier this week, the head of the International Energy Agency warned that vital supplies remain blocked by conflict in Iran – as a result, many airlines have already started axing routes.

The blockade of the Strait of Hormuz is holding up major supply chains which has led to a huge hike in fuel costs – and shortages.

ACI Europe, which represents European airports, said the key trade route must open within three weeks or fuel reserves will run drastically low.

In response, a number of major airlines have been cancelling flights in preparation for shortages – with thousands affected.

Here are the major eight airlines that have already cut back on their routes…

United Airlines

United Airlines said that five per cent of flights would be cancelled in the second and third quarters of 2026.

With up to 5,000 flights a month – working out to around 4,000 domestic and 800 international routes – this means it affects around 250 flights a month.

United Airlines has the world’s largest airline fleet with more than 1,075 aircraft.

Scandinavian Airlines

SAS was the first major airline in Europe to axe flights because of of the cost of fuel going up.

It said in mid-March that it would cancel 1,000 flights throughout April.

Lufthansa

Lufthansa‘s subsidiary airline CityLine is to cease operations due to both the Iran crisis and ongoing strike action.

The division ran business flights between European airports but will ground its entire fleet of 27 aircraft. 

Flight routes typically connected London to Frankfurt and Munich.

It will also cut six planes from its international fleet after the summer holiday season, warning that the cutbacks could last into winter.

KLM

Dutch airline KLM has cancelled 160 flights for the coming month, but has said it will affect less than 1 per cent of its schedule

The airline insists there is no shortage of jet fuel, saying the move is purely down to spiralling costs.

A KLM spokesperson said: “Passengers affected by these changes will be rebooked onto the next available flight.

“KLM expects a busy May holiday period and is making sure passengers can travel to their holiday destinations as planned.”

Cathay Pacific

Cathay Pacific has confirmed that two per cent of passenger flights will be cancelled from May 16 to June 30.

This will affect a number of regional routes, as well as longer-haul connections to destinations across Australia and South Asia.

Its budget airline HK Express is set to cut six per cent of flights due to increased costs.

Air New Zealand

Air New Zealand announced in March that it will be cutting back on flights over the next two months.

Chief Executive of Air New Zealand Nikhil Ravishankar said the airline would see roughly a five per cent reduction in its services which would continue until the beginning of May 2026.

This reduction equates to around 1,100 flights which in turn will affect 44,000 passengers out of its 1.9million.

Norse

Norse Atlantic Airways has removed all flights to Los Angeles International Airport (LAX) from its summer schedule.

A spokesperson said: “Due to the continued increase in fuel constraint risks, fuel prices, and the resulting impact on our operating costs, we have had to make the difficult decision to suspend our LAX operations this summer, May to October.”

Norse operated a summer route from London Gatwick to LA.

British Airways

British Airways will drop its service from London Heathrow to Jeddah in Saudi Arabia permanently from April 24, 2026.

The airline had been operating a four flights a week service since November 2024.

BA said the terminating of the service was due to a shift in demand rather than fuel costs as hasn’t axed any flights because of that so far.

Virgin Airways

Virgin Atlantic announced earlier this month that it would be permanently scrapping its London flight to Riyadh from April 7, 2026.

It said some of the reasons were the “evolving situation in the Middle East” and “operating costs.”

Here’s why you should book your summer holiday now – easyJet boss says.

And here are the European holiday destinations Brits are flocking to instead of Turkey and Egypt due to Iran crisis.

RISING fuel costs linked to the war in Iran have forced a major airline to slash more than 100 flights – including services to and from London.

Dutch company KLM is axing 160 flights across Europe over the next month as soaring fuel prices pile pressure on the industry ahead of the busy summer period.

The cuts will hit routes in and out of Amsterdam’s Schiphol Airport, with departures and arrivals split evenly .

Despite the disruption, the airline insists there is no shortage of jet fuel, saying the move is purely down to spiralling costs.

A KLM spokesperson said: “Passengers affected by these changes will be rebooked onto the next available flight.

“As these are destinations KLM serves multiple times a day, such as London and Düsseldorf, travellers can usually be accommodated quickly.

HOLS HORROR

“KLM expects a busy May holiday period and is making sure passengers can travel to their holiday destinations as planned.”

KLM’s flight cancellations comes after the head of the International Energy Agency Fatih Birol said mass flight cancellations will begin “soon” if the Strait of Hormuz remains closed.

“In the past there was a group called ‘Dire Straits.’ It’s a dire strait now, and it is going to have major implications for the global economy”, Birol told AP.

Adding: “And the longer it goes, the worse it will be for the economic growth and inflation around the world.”

Birol’s deadline means airports could face critical fuel shortages by May, causing travel chaos for Brits heading abroad during the school May half-term holidays.

Oil prices have soared since the start of March after Iran closed off the Strait in response to US-Israeli forces bombing.

The Persian Gulf chokehold sees around 40 per cent of the world’s jet fuel supply pass through.

It comes after ACI Europe, which represents European airports, said the key trade route must open within three weeks or fuel reserves will run drastically low on Friday.

A number of airports in Italy have already warned that they were running out of fuel.

According to local reports earlier this week, Brindisi-Casale Airport confirmed that Jet A1 fuel was not available for a short period of time.

And British Airways has announced it will permanently axe its service from London Heathrow to Jeddah in Saudi Arabia from April 24.

The airline had been operating a four flights a week service since November 2024.

But a shift in demand, due to the conflict in the Middle East, has led to the airline terminating the service.

KLM stressed the cancellations make up just one per cent of its European schedule.

But the move will still spark concern for Brits planning trips abroad as airlines battle rising operating costs.

It comes as carriers across Europe scramble to balance the books amid the fuel crisis.

Earlier this month, UK airline Skybus pulled the plug on all future flights between London Gatwick and Newquay.

The route, which launched in November 2025, had been backed by Cornwall Council and the Department for Transport under a public service scheme due to run until the end of May.

However, a slump in passenger numbers combined with higher fuel costs forced the airline to ground the service early, with its final flights taking off on April 2.

The latest cuts raise fresh fears of further disruption for holidaymakers as the peak summer season approaches.

Meanwhile other vital UK services could also face shortages if a deal to end the Middle East war is not struck soon.

Medicines UK, which represents companies making 85 per cent of NHS prescriptions, said NHS patients could face prescription shortages within weeks.

This could place “significant pressure for the NHS as early as June”, the organisation warned.

And Brits could even face shortages of supermarket staples such as beer and meat as officials fear the blockade of the Strait could cut vital carbon dioxide supplies.

CO2 is used in food packaging to improve the shelf life of salad, packaged meats and baked goods – and also slaughtering nearly all pigs and most chickens.

Tim Lang, professor of food policy at the University of London, who has been a member of several government bodies including the UK Council of Food Policy Advisors, told The Sun that the UK has “next to no food storage”.

A NUMBER of popular holiday destinations in Spain are losing their Ryanair flights this year.

The budget airline confirmed last year they would be cutting 1.2million seats across the country,

Follow The Sun’s award-winning travel team on Instagram and Tiktok for top holiday tips and inspiration @thesuntravel.

The cancellations are due to the increase in airport fees, which would mean airlines paying an extra 21 per cent from 2027 to 2031.

An initial increase of 6.44 per cent has already been introduced back in March.

At the time of the announcement, the CEO of Ryanair, Eddie Wilson said: “Next winter we will make further cuts to regional airport services and I remind you that our total traffic in Spain for this summer will only grow by 0.5 per cent compared to 9 per cent in Italy, 11 per cent in Morocco or 20 per cent in Poland.

“Aena’s proposal to increase fares by 21 per cent is regrettable, but not surprising, as this airport monopoly has a history of applying the highest fares at the expense of traffic development, especially at Spain’s regional airports, which are 70 per cent empty.”

He also commented that if the fees were increased it would “make even the most popular airports in Spain uncompetitive” and that Ryanair would turn to “other places in Europe where rates are more competitive”.

Here are some of the destinations being affected.

Asturias

All Ryanair flights to the coastal region of Asturias in north Spain have been stopped.

If you do want to head to Asturias though, British Airways, Iberia and Vueling all fly to the airport from the UK.

Vigo

All flights to the port city of Vigo in northwest Spain were suspended on January 1.

Routes cancelled include from London Stansted Airport.

There are currently no direct flights from the UK with other airlines to Vigo – instead, you would have to book a flight to Madrid then to Vigo.

Alternatively, Porto Airport is less than two hours away.

Tenerife North

All Ryanair flights to Tenerife North were stopped over the winter.

This included a route from London Stansted Airport.

If travellers want to head to Tenerife now, their best bet is to fly to Tenerife South, which Ryanair flies to from a number of UK airports including London Stansted, Bristol and Birmingham.

Valladolid

All flights to Valladolid in northwest Spain have been scrapped with the airline’s base closed at the airport since winter 2024.

If you wish to travel to Valladolid, the best way would be to fly to Madrid which is under two hours away.

Jerez

Ryanair has cancelled all of its direct flights to Jerez in the Andalusia region.

However, if you still want to fly to the destination, you can do so from the UK with Jet2.

Jet2 offers flights to Jerez from Birmingham, Leeds Bradford, London Stansted and Manchester.

Alternatively, you could fly to Seville and then hop on a train that takes less than an hour to Jerez.

Santiago de Compostela

Santiago de Compostela Airport in the Galicia region will no longer have a Ryanair base, which will mean fewer flights to the destination.

While the budget airline does still operate flights to and from the airport, Sun Travel found that these are mainly to destinations within Spain.

There are a number of other airlines that fly to the airport though, including British Airways, Vueling and Iberia.

Santander

Ryanair is set to reduce its capacity from Santander, known for its stunning views of the Bay of Biscay, by 38 per cent.

But the airline is still operating UK flights to the airport, including from Manchester, Birmingham and London Stansted – just a reduced number.

Zaragoza

The airline is also reducing flights from Zaragoza – the capital of Aragon in northeastern Spain – by 45 per cent.

While the airline does still fly to the airport, it is mainly from destinations outside the UK such as Milan in Italy.

Sun Travel found one route from the UK to the airport, which is from London Stansted.

Vitoria

There will be a slight reduction in Ryanair capacity to Vitoria (two per cent), which is the capital of the Basque region.

Despite this, Sun Travel found no routes from the UK to the Spanish airport with that airline.

If you want to head to Vitoria, your best bet is to fly to Bilbao Airport which is about an hour-and-a-half away.

Girona

Routes from Girona in Catalonia are also set to be reduced by 11 per cent over this summer season, according to Euro News.

Sun Travel found that there are currently still flights from UK airports including London Stansted, Bournemouth and Birmingham to the airport.

In other flight news, British travel misery is set to get worse as European flight cancellations stretch to five days.

Plus, two major airlines are set to hike flights by up to £90 due to rising jet fuel prices.
