I emailed JetBlue a couple of weeks ago w/this same question. They had no answer for me but to keep checking their website or call them - the email mentioned they were adjusting/adding new flights, etc. My TA said probably not until after the New Year but I kept checking once a week. I did however "give up" and booked US Air - I just wanted as many details taken care of as possible.
You could go ahead and book your resort and package (if you're getting one) and add airfare when it comes out. We booked our resort 5 months ago and then added the package in August. Good luck!
