Yes, LAX is quite something. I don't know how closely you follow the industry outside jetBlue, it may be difficult when you're in the air and not behind a monitors (not something you should want to change if you're enjoying flying, trust me) but LAX is causing all the airlines a major headache. A Southwest Airlines spokesperson was quoted as saying that if all their airports were like LAX they would have gone into the steamship business, it was funny.

Between United's Dulles hub, and Southwest's presence at BWI, Southwest growing at Dulles, and the incredible difficulty of getting to Dulles from downtown D.C., I don't see Dulles becoming a large station for jetBlue. I certainly don't see alot of IAD-RDU/BNA/CLT but I could be wrong.

I would like to see a couple more cities out of JFK this year before jetBlue focuses entirely on connecting the dots (which to me translates to New York gets shafted in favor of Boston and Dulles)

I have a feeling Nantucket is going to be HUGE this summer. I would NOT be surprised if emergency flights aren't added on short notice this summer. Alot of people own homes up there and will pay any amount of money for an alternative to that drive, I also think it will influence wealthy vacationers considering places to go for a week in July. Drive to the cape or fly a real plane to Nantucket and not have to deal with the Lexus, I'll be curious to see...
