Again, you fly from DSM, I can't help that I left there 11 years ago.
DEN $39, Portland $89.00, SMF $89, ONT $59, Tampa $99, KCI $79, SEA $89, LAX $79, PHX $39.00 all one wayof course and direct. Point is OMA isn't the best SWA outpost. But when I have to go to IOWA I fly to OMA. I won't fly UA! First Class? who the hell fly's first class on CRJ? Oh legacies that are merging................
I couldn't even find a flight from OMA to DEN. There's no reason to expect that SW would be any cheaper out of Des Moines than it is out of OMA. People thinking that SW is going to show up and everyone's fares are going to drop through the floor are simply mistaken.
You can find fares in the 190 dollar range roundtrip to Orlando from Des Moines on NW from time to time, for instance. That's as cheap as most SW flights.
At any rate it doesn't matter where you are, but where you're wanting to go. The closest SW service to MSP, for instance, is Chicago or Omaha. That's a LONG drive once you get there. There are 17 whole STATES that SW doesn't service, and only 6 states that have more than one city that has SW service. NW services 6 cities in Iowa alone. I'm not ragging on SW, really, just that it's not a great solution for frequent travelers that have to go to a lot of smallish towns, and even big cities, that SW doesn't service. I know I can go to NW and get pretty much anywhere I need to go, or at least as close as I'm going to get flying (with a few odd exceptions here and there). On top of that, their rates are competitive with SW, for much better service, IMO.
CRJ-900s have a 16 seat FC cabin, and it's quite comfy. DM is getting more and more of those flights. UA has 737 service, as well as ERJ-175s which both have FC cabins.
