Ginger ale - it gives you wings.

I'm not always a fan of The Oatmeal - sometimes he's kind of a jerk - but this comic [warning: inappropriate language!] is EXACTLY how I feel about ginger ale on planes. I thought I was the only one!

[Okay, okay, these days I also drink a lot of water and some orange juice on planes, but ginger ale is still my traditional plane drink, even though I don't really ever drink it on land.]
