Here are the top 5 airline travelers' complaints from TripAdvisor.com. I'll count them down backwards, because that's what Casey Casem would do!
5. Annoying passengers
4. Long security lines
3. Flight delays
2. Extra fees
1. Uncomfortable seats/no legroom
It's true that airlines are moving the seats closer together to squeeze a few more people into the plane. They could really learn from the people who make crayons, skip the seats, and just stack us all in there standing up, like the big box of 64 Crayolas!
