The roominess of it all.

The food.

The idle time while standing upright.

Duty-free shopping (clue me in here, does anyone actually take advantage of this?)

Pre-completed Sudoku puzzles.

The elbow room

Month-old episodes of 60 Minutes.

The comforting feeling of being in complete control.

Free airport wi-fi.

Adjustable air nozzles.

Watching someone attempt to close the overhead bin at least 15 times before giving up and letting the attendant deal with it.

Ear-popping fun.

Cab rides.

Quality reflection time.

Fumes.
