Because I am a geek who feels the need to categorize everything, I try to track which airlines carry which spirits.
I started a page to share this, located at this link: Airline Drink Menus.
I'll keep filling it out over the coming months, but should you feel like enabling my geekery you can help: snap a picture of the spirits and cocktail selection of your next flight (usually in the airline magazine) and email it to me. Make sure to let me know which airline, domestic or international, and what month you flew so I can categorize it correctly.
Looking at the menus I have there already there are some interesting choices. As usual, Virgin is doing cool things. On Virgin America, they have craft beer: Black Star Beer, Gordon Biersch Mãrzen, 21st Amendment Brew Free or Die! IPA. On Virgin Atlantic, they have a guest spirit as a promotion: Akvinta vodka.
I wish more airlines were more adventurous with their spirits selection- Virgin Upperclass has an actual bar with barstools where you can sit, but then the spirit selection is mostly well liquor. They should have rows of single-malt scotch and other high-end brands to try. They've got a captive audience of high income-earners (except when I'm on the plane) who can spend the money on bottle of the spirit when they land.
In the meantime, let's keep watching to see where things stand.
