“There are only three types of people in this world -- window, middle, or aisle --
which are you? ~ Unknown
Another reason I like window seats is to have the option of using the window to lean against if I want to rest or sleep. It is not comfortable but it is better than nothing. There is also no chance of flight attendants and other passengers bumping into you as they pass your row. And you don’t have to get up every time someone in your row decides to get up.
Aisle people have the benefit of being able to get out of their seats when they want without having to bother their seat mates. Plus they have the advantage of getting off the plane sooner which helps with connecting flights.
Statistics show that women more often than men pick the window seat, this may be due to the fact some feel the aisle seat has a bit more leg room for the taller framed men. Other statistics show window people tend to be more relaxed, where as aisle people feel they need to work on something while they are in-flight or have more control over their movement on the plane.
Regardless of which you seat you choose and it seems we all have a preference; the airlines seem to have figured this out and now charge you extra to select your favorite seat.
