The Secret Button on Your Aisle Seat That Airlines Don’t Tell You About
Most travelers know the basics of their seat: the tray table flips down, the recline button shifts the back, and the seatbelt sign overhead controls when you can get up. But airplanes are full of small details that slip past even the most frequent flyers. In fact, some seats have one feature that rarely gets mentioned in announcements or in-flight magazines.
The Real Struggle Of Shared Space

Traveling in economy reminds you how little personal space you actually have. A stranger’s elbow might hover too close, meal trays shrink the space in front of you, and stretching your legs without blocking the aisle can feel like solving a puzzle.
Every small adjustment counts when you’re flying in tight quarters, which is why this small hidden button can make such a big difference.
A Moveable Armrest
This button or small lever is placed beneath the hinge of many aisle seat armrests. Press it, and the armrest pops up and swings back, thus opening up a bit of space where it once pressed against your side. On certain aircraft, the button is a pin you push; on others, it’s a round piece under the armrest.
It’s not really designed to be obvious, which explains why so many passengers sit through years of flights without ever noticing it. Online forums and viral videos show passengers using it to slide out of their seat more gracefully, stretch during long flights, or avoid that awkward shuffle when trying to reach for a bag in the overhead bin.
Why Airlines Include It

The feature isn’t just about comfort, though. The Federal Aviation Administration requires that on aircraft with 30 or more seats, at least half of the aisle seats in accessible rows must have moveable armrests. The main purpose is to help passengers with mobility challenges get into their seats more easily. It also makes cleaning and servicing the cabin quicker for crews between flights.
Safety First
There’s also a reason airlines don’t highlight this feature in pre-flight briefings. Armrests sticking out into the aisle can create hazards. Safety inspectors have flagged cases where upright armrests blocked pathways during evacuation tests. Some airlines have even had to adjust seat designs to prevent obstructions.
Cabin crew are trained to remind passengers that armrests, like tray tables and seatbacks, must be down during takeoff and landing. In the event of a sudden stop, a loose armrest could swing forward with force, which is why it matters that they’re in place during critical moments of the flight.
Where To Look

The button isn’t available on every aircraft or in every aisle seat, but you’re more likely to find it on certain models. Reports point to older Boeing 737s, Airbus A320 series jets, Boeing 757s and 767s, and even newer widebodies like the Airbus A350. Some configurations include it throughout the cabin, while others limit it to specific rows. If you’re curious, the simplest way to check is by sliding your hand under the aisle-side armrest near the hinge to feel for the release.
