I wouldn't want to see Sam Adams, but it would be a slight improvement over Heineken and Fosters. I think selecting one or two mass-marketed pseudo-micro brews would be most efficient; while a good idea (and one that I would like to see implemented), I think carrying region-specific beer on international flights might be a bit too complicated (but what do I know about airline catering?). My highest priority is improvement of the wine selection on both domestic and international flights.
