careful don't want to hurt thier feelings.

Very different business models and beliefs at the managemnt level. JetBlue doesnt mind paying big bucks for gate space, landing rights, and all other high upfront costs...........think JFK, LAX, SFO, EWR, DCA, LHR, AMS. (They just seek opportunites to take money from work groups and save on labor)
Where as Southwest has completely left EWR and possibly other high cost airports and usually if serving a large market is more concentrated in the smaller/cheaper place ........HOB not IAH, MDW not ORD, LGB not LAX, BWI not IAD, DAL not DFW.......if they had the opportunity to fly to London......it sure would be LGW...I dont see them paying for LHR.
