I prefere the middle seat on airplanes with the assumption that the two strangers are not crazy.
Pros: Not having your shoulder and leg bumped by every single person that walks by.
Getting up to use the bathroom isn't as complicated as the window seat.
It actually has the most leg room after take off. After take off, you are allowed to have your personal item under your legs instead. Switching gives you more leg room than the other seats.
It's actually the least awkward seat when recieving snacks. No big reach from the attendant.
You can almost always get really close to the front of the plane if you are booking closer to the flight.
You by far get the best AC fan.
It's fun to sit in awkwardly when the ailse seat is a no show but the window seat is still there.
