There is currently no way to view the seat map before purchase, HOWEVER, if you call 1-800-JETBLUE, the agents will be happy to check what specific seats are available for any flight.
This feature will be introduced on jetBlue.com when the new reservations system (which last I heard has been delayed) is up and running. I think it will be available to TrueBlue members...be patient, I would give it up to 15 months or so.
