Gone are the days where you had to worry about your legs during long airplane rides as there's a new airline seat design which aims to offer adjustable leg room top ease out some pain of flying.

As explained in a patent application by B/A Aerospace, the seats would accommodate the different heights of passengers by rolling backwards and forwards on the tracks already present on the aircraft's floor, meaning if a tall person wanted more leg room, they could have it at the expense of passengers shorter than them, News.com.au.

Passengers would have to provide their height information once they check in, after which the flight crew would use an app that controls the movement of the seats' gears and adjust the seats accordingly.

However, while this may be good news for taller travellers, it was very much possible that shorter passengers won't like sacrificing their leg room.
