Latest rumor is that STL could become a crew base. Usually a station has to have quite a few flights to become a base. STL is growing and has over 100 flights per day. Don't think that LGA will qualify and I think the determing factor about a crew base is the number of overnights a station has. STL usually has 10 sometimes higher that would be a big savings just on crew hotel cost. Usuallly when a base becomes a crew base it is pilot first and then FA.
