I recently got a good deal on a flight from SFO to MCO on Priceline.com but they gave horrible times, pretty much mirror images of what I requested. I wanted to spend the weekend with my girlfriend, leave late friday night and catch the redeye back to SFO on Sunday. They give me a flight leaving 6am Friday, returning 7am Sunday! Come on!

I know priceline probably has reams of legalese spelling out that I can't change, complain, or do a dang thing about this, but what if:

I arrive when I want to arrive Sunday night. Will Delta (the carrier priceline chose for me) be obligated to put me on a flight as long as there are seats? Will they force me to pay a bunch of money for the privledge, or will they make me buy a new ticket altogether?

I'm looking to hear back from people who've been in this experience with priceline.

Thanks!
