How to deal with flying as an unaccompanied minor
Try to get an aisle seat if possible.
Even if you enjoy a window, get an aisle seat. This will avoid the awkwardness of having to step over people to go to the bathroom.

Available choices: (I). Pack what you will need to keep you entertained. Laptop, ipod, nintendo ds, etc. (II). Sometimes you end up falling down the aisle. When this happens you get a flashback, look in the mirror and try to avoid hitting your head on your chin. (III). Always check out the aisle seats before actually sitting in one. When you are taking a seat, stay where the aisle seat is closest to the window and try to look at the objects around you by looking straight ahead. (IV). If you do need to step over people or seats, talk to your parent or guardians about which seat you can use while driving. A parent can even inform you if there are seats available for you, to determine which one is considered the most comfortable.. The answer should be
(I).
