sometimes you just gotta get lucky. I can't drink because I'm underage, but once time the flight attendants handed these "free drinks on us slips" to the people in the first row of coach. Personally I think bringing your own alcohol in a three ounce container is thrifty, but also sketchy. The only way to drink in style is to be in first class, and that costs more money or you have to be related to someone who works for the airline.
