I can't say I've ever gone to the bar and had a drink in the airport--usually if I am flying somewhere it's in the morning so it's just not a time that it would appeal to me. The one time I drank the glass of wine on a transatlantic flight it gave me quite a buzz...and it really wasn't that pleasant. Apparently alcohol hits a lot harder at 35,000 feet. It didn't do that much to help me relax and sleep on the plane either like I thought it would, even despite the fact that I had also taken a Benadryl at the beginning of the flight to try and help with that (which it really didn't). The moral of the story is that I think on future flights I'll steer clear of any alcohol. I'd rather be in full possession of my faculties in that situation anyway in case there's an emergency...I think that's part of why I didn't like how the glass of wine made me feel on that flight.
