Don't know if it's fact or fiction, but it wouldn't surprise me if some sort of change is in the works.
Although I like to have a drink when I fly, the airlines certainly have the right to stop serving booze whenever they feel like it. We're talking about transportation companies here - not the neigborhood pub.
I doubt it would affect my travel plans either way. Alcohol availability - although something I'd like to have - would be about 15th on my airline selection criteria.
