Airplane drinks

Although I never order it anywhere else, I almost always order Ginger Ale when I fly. I try to justify it on the basis that I once heard that ginger is a natural cure for motion sickness ... but I have never had a problem with motion sickness.

Upon asking around, I found out that other people also have "airplane drinks". My wife's is tomato juice (and she normally drinks something that other people only drink on airplanes!). What's yours?
