The best and worst seats on a plane have been revealed by a plumbing expert – and there is one particular spot that you should always swerve if you possibly can

Travellers eyeing up seats on budget airlines like Ryanair, easyJet, TUI, and Jet2 might want to give seat 11A a miss.

While flight attendants have their own insider tips for snagging the best spots on a plane, one plumbing expert has let slip that it’s not just about avoiding the smell from the loos – it’s also about how close you are to them.

Brenna Ryan from Victorian Plumbing has dished out advice on choosing your seat with the toilet’s location in mind. According to her, passengers will generally feel more at ease if they’re mindful of the distance to the nearest loo.

She recommends: “When choosing where to sit on a flight there are a few important factors to note. Think about how often you visit the toilet. If the answer is pretty frequently, take that into account when deciding which seat to book.”

She further explains: “The first thing to consider is which part of the plane to sit on, planes usually have a toilet both at the front and back, so look to sit there when possible and avoid the middle of the plane furthest from the toilets.”

For the ultimate blend of comfort, minimal smell, and easy access to the bathroom, Brenna Ryan champions seat 4C. This aisle seat towards the front of the aircraft is ideally positioned – not too close to the front that you’ll have a queue beside you, yet sufficiently distant from any potential bathroom odours.

Brenna, an expert in the field, has crunched the numbers and come up with a seat that she claims is the absolute worst on any plane.

She elaborated: “The worst seat on the plane is 11A. Not only is this seat further away from the bathroom, it is also a window seat which makes it more difficult to manoeuvre out of for frequent bathroom breaks.

“Not only do these issues cause inconvenience, but the seat also boasts no windows, despite being a so-called window seat.”

This isn’t the first time flyers have been warned about hasty decisions during booking. Ex-flight attendant Bobby Laurie has pointed out a blunder many make that could end up costing them more for an economy ticket than a First Class one.

Bobby has advised against repeatedly searching for flights using the same search engines, devices, and IP addresses. He explained that airline prices can skyrocket based on the volume of searches for a particular route; hence, increased interest leads to higher prices.

Speaking to Business Insider, the co-host of The Jet Set said: “If a lot of people are searching for economy flights, the price will rise. I’ve seen many times situations where first class or premium economy was cheaper than the coach ticket.”

While this might not always be the case, there’s a silver lining for those dreaming of luxury travel without the hefty price tag – there are strategies to snag those elusive First Class seats for less.

One strategy is to join airlines’ loyalty programmes – particularly beneficial if you’re a frequent flyer with them.

Not only can you accumulate points that could be used towards the luxury cabin, but you also get early access to exclusive deals and offers – and when there are opportunities for staff to distribute upgrades, you’re likely to be higher on the list.
