Regarding other hubs: Why do we need it?
Say you want to take a vacation to the worst city in the united states (san francisco). If you are bitching about laying over in DFW instead of Denver, please, drive to kansas city you ungrateful SOB. DFW is not that far off.
Also, who would fly to denver? American sure doesn't. United isn't signing an MHK contract especially after how we clowned great lakes. Frontier? LOL. I'd say flip has better places to go.
Southwest? Airtran? Are you people high? Can we be a bit realistic? let's focus on treating AA well. JMO.
