Feeling a Bit Ill on Your US Airways Flight?

Here, use this bag sponsored by Doritos Chips...

Among the first of the airlines to sell ad space on seat-back tray tables, US Airways is now planning on selling space on air sickness bags, among other things.

I always thought the best way to keep that seat next to you unoccupied was to hold an air sickness bag - open - in front of you, with your head down and your eyes closed. Now, I can read the ads instead.
