I checked the site, and sure enough:
"From $79 each way, Between Boston and Ft. Lauderdale, Orlando or Tampa. 7-day advance purchase is required. Tickets must be purchased on jetblue.com and travel must be completed by February 10, 2004. Service begins January 7, 2004. "
No wonder Song is adding flights out of Boston. Flights out of Providence or Manchester NH were no big help for us as we live 15 miles from Logan (with quick access by T or taxi). So a genuine discount airline (other than Song, that is) is a welcome change. Having been a Delta frequent flyer since 1985, I will likely still stick with Song, and also for the extra help we get from the wonderful crewmembers with our wheelchair-bound son (Delta/Song being among the few airlines that actually give us the extra help we need). But competition is good. The pressure will likely weed out secondary players in some of the routes, like American on the BOS-MCO route.
This was not old news to me, so thx for letting us know!
