Again, the CRJs were really just stretched Canadair Challenger 601s. They were NEVER built to do 10 legs per day. Now that the cycles are so high, they are coming up on very expensive checks. (as explained to me by management types). Those checks are more money than the planes are currently worth. Also, when a 50 seat RJ goes up against an Airtran 717 or a Southwest 737, it loses everytime. You bring up LAS on mainline. LAS and Hawaii flights aren't that profitable because there are a lot of frequent flyer awards dumped on those flights, or just very cheap tickets to compete with Spirit etc. Not every city is like that. A friend of mine in ATL had to do a 1 day meeting in DCA and flew roundtrip on Delta, and the roundtrip ticket purchased the day before cost about $900. LGA, DCA, BOS, etc make a lot of money. LAS and HNL, not so much.
