Exactly!
Gup...I understand what you're saying. But it's not like we have parts depots in every city we go to now. Bottom line is, the 717 will transition through maintenace hubs at some point within each day or two. So if it's flying to SEA, it will probably hit OAK, PHX, or DEN. If it's flying to FLL, TPA, or MSY, it will probably hit ATL or DAL. It never will be too far from a MX base somewhere, so therefore having it fly to big markets, medium markets, and small markets is in the realm of possibility.
Remember...the 717 has the same seating capacity as your -300's (or is it the -500's; I can't remember). Does SWA put those 737's in only small markets, or do they put them in most markets and run them on the flights that have less demand than a -700 is suited for?
