BA's basic First service includes Glenmorangie with the Port Wood Finish as their single malt, and JWBlue as the blended. As noted , they also carry Knob Creek for bourbon lovers. Frapin VIP XO is their house cognac as of a couple of months ago. I think supply may also be a reason we don't see overly exotic single malts. It takes a lot to provision a fleet.

i've enjoyed recent flights in the front cabin of MX, sampling the tequila selection. Standard complement is made up of Cuervo Tradicional, Grand Centenario Reposado and Reserva Antingua 1800. They also provide a liqueur, Agavero Licor de tequila which is akin to a Drambuie, and a sweeter offering, Dobel "Un sueno hecho licor", which is like a Bailey's.

One of the few nice things one can say about NW is that they do try to carry a seasonal microbrew. I would like to see at least one such selection on other carriers, in addition to the mass market beers. [BA does carry London Pride.] And from time to time AS and Horizon also offer local microbrews from cities in the NWest USA.

One often gets a more interesting sampling of microbrews in airport lounges. If only some carriers could be as adventurous in the air!
