If you want free booze when you fly internationally, you might want to check out The Ultimate List of Airlines That Serve Free Alcohol list compiled by the website Maphappy.org. I don’t drink alcohol — especially on planes so I have no idea who serves it or doesn’t. But I know a lot of people who need a drink (or two) to take the edge off of flying or to fall asleep. So if you fall into that category, then you’ll probably want to check this list and avoid most U.S. airlines, with the exception of American and Delta.
Remember: One drink in the sky is equivalent to two on the ground and dehydration happens much faster.
