they're pretty cheap and they fly a TON of out JFK and they fly a little out of LGA.:)
I recently saw something online somewhere that JetBlue is doing a fly all you want for $599...i didnt read anything about it, but if anyone flies a few times a year, it might be worth looking into.
Joyce I'm not sure exactly where you would/could fly out of but check Allegiant air. They fly into the Orlando/Sanford airport (which is about 20 minutes out of Orlando) for pretty reasonable prices; usually $80 each way.
Also use the site Kayak.com to get some price references to go by. There used to be an airline called Spirit Air that made tons of flights between NY and FL for good prices but I'm not sure if they are still around.
You will definately be able to find much better deals than what you saw. That is crazy.
another site to try is sidestep.com. It checks most travel sites and gives you quotes and links to the best flights.
Prices might go down when it gets closer to. I've had lucky with that when flying from NY to Indy. You don't want to wait until the last minute necessarily. Just keep an eye on it.
Check Spirit. I have flown them a few times to FL and they have always been the cheapest.
I think I paid in March about 300 for my flight. I have found them even cheaper, but March is usually one of the most expensive months. I would wait a bit and shop around for a good price.
