My least favorite airline is now US Air. First, they charge for even the first bag. That is insane. Secondy, they charge $2 for a can of diet coke. Seriously? No peanuts or pretzels - nothing at all. They say they have snack packs, but they were all sold out when they got to me (for a 4 hr and 50 min flight). Then, I open the tray table, and it has an add on it. You have got to be kidding. I did upgrade to first class for one leg, and they don't even serve the drinks before you take off. I absolutely cannot believe it. Rude staff as well. Unbelievable.
