Why the Seat Pocket Is the Worst Place for Your Phone on a Plane — and What to Do If It Falls Between Seats

Where your phone ends up during a flight matters more than you might think. A forgotten device is a hassle, but one wedged between the seats can turn into a genuine safety risk.

It's a convenient little compartment right in front of you, but it's also the last place you want to leave something as valuable as your phone. In fact, flight crew members and other experts advise against it — and for good reason.

In many ways, it makes sense that the seat back pocket is the go-to spot for items like your phone, headphones, or even your passport and wallet.

You may have them in hand as you board, and once you've stowed your bag in the overhead bin and started getting settled, you might tuck everything into the seat back pocket as a quick and seemingly safe way to store it.

Television host Samantha Brown, a seasoned traveler herself, advises against this habit for one main reason: "You'll always forget it. Always."

According to Brown, keeping your belongings out of the seat back pocket can spare you the stress of rearranging your international travel plans to squeeze in a trip to the nearest U.S. Embassy or Consulate for a replacement passport.

But the risk of forgetting your items isn't the only reason to reconsider using these pockets. As it turns out, they can be pretty gross, and all kinds of unpleasant things may end up inside them.

In a Reddit thread, a flight attendant revealed that the seat back pockets "are cleared of rubbish but never 'cleaned.'"

They then listed some of the things they've found and seen in those pockets: "Dirty tissues, sick bags, knickers [underwear], socks, peoples feet, gum, half sucked sweets, apple cores... and then next flight you go and put your phone/laptop/iPad in there."

Beyond forgetfulness and hygiene concerns, there's another hazard to watch out for. Even if you decide against using the seat back pocket, your phone could still slip and fall between the seats in the chaos of getting settled.

Christina Ling, the flight attendant instructor behind the TikTok account @flightattinstructor, warned that if your phone drops between the seats, you shouldn't try to retrieve it yourself.

While fishing a fallen phone out from between airplane seats may seem harmless, it's actually a safety hazard. Moving the seats and jostling the phone while trying to reach it could damage its lithium battery and cause it to catch fire.

There have, in fact, been documented incidents of phones slipping through seats and catching fire on planes. Back in 2020, a phone stuck in a seat mechanism caught fire on a flight bound for London Heathrow Airport.

That October, roughly 40 minutes before landing on the service from Miami, a passenger who had been flying in premium was woken and told to return her lie-flat seat to the upright position.

She then went to the restroom to freshen up, and one of the attendants, who was putting away the flyer's bedding, noticed a smell of "sulfur" coming from the seat. That's when the attendant spotted smoke, according to a report by the UK Air Accidents Investigation Branch (AAIB).

"At this point they heard a 'hissing' sound and a large plume of gray smoke emitted from the seat in a 'tornado' motion. They remembered seeing an orange glow in the seat area amongst the smoke," the report said.

A senior crew member put out the fire with an extinguisher, and the phone was found trapped in the seat. The fire service met the aircraft when it landed at Heathrow, but the plane sustained no further damage.

A fire on board an airplane is the last thing anyone wants to witness. If your phone ever slips between the seats, skip the rescue mission and call a crew member for help instead.
