Psss – Did you know that there was a Secret Button to Raise the Armrest of an Aisle Seat on an Airplane?
Many aisle seats have a hidden button or lever that will let you raise the armrest.
There are a few planes that do not have movable aisle armrests. However, most of them have a small lever or button on the underside of the armrest, near the hinge. Pushing or sliding this lever will release the hinge lock, allowing you to raise the armrest.
