I'm actually not sure where I'll be flying yet, but it will be in the US and to major (LA) or semi-major (Rochester) cities. Obviously I wouldn't want to build up status on NWA only to find that they don't fly to wherever my next project is located; but that's true of any alliance I choose. So I need to consider who has the most locations in an alliance, as well as which alliance is best to build status on.
