Sickness

Man I hate airplanes. The last two times I've been on a 7-seat-wide plane coming into SFO, I have fallen asleep for a couple hours and woke up sick.

Less annoying is the voices saying "Thank you for choosing Delta!" when in reality I just take the cheapest ticket Kayak can find.

Really they should say "Thank you for not going inordinately out of your way to avoid Delta!"
