Intersting topic for conversation, Herb Kelleher is so unpredictable when deciding where to fly. I read soewhere recently that over 100 cities have requested Southwest service in the last year or so. If I had to put money down on it, there would be two distinct areas that, in my mind, beg for Southwest service:
1) the mid-Atlantic region: I see SW serving Charlotte, Columbia, Greenville/Spartanburg, Charleston area before too long.
2) the upper midwest: I'm envisioning Milwaukee, Minneapolis, and Des Moines.
In order, I'd probably go with GSP first, then MKE, CAE, GSP, MSP, CHS, and CLT.
Comments on DEN and ICT: SW tried DEN years ago, and it didn't work, too many hassles there. As far as ICT goes, they've been trying for years to get SW in there (because their fares are so high...very little competition there since the Braniff days...), but one sticking point has been the Wright Amendment (no DAL nonstop/direct service to points outside TX, LA, MS, NM, and OK until recently extended to MS, AL, and Kansas).
Now that I've written this, I think Herb might just finally give the go-ahead to Wichita. and it would be about time.
