Glad the Kayak thing helped someone. When I booked the next morning after previewing on Kayak the night before, everything was exactly the same on the Jetblue site as it had been on Kayak. And I was looking at a ton of different options (BDL, HPN, BOS, Newburgh, Newark, JFK . . .). My take on it was that since Jetblue sells through Kayak, they had to load it in time to be up and running on both the Jetblue and the Kayak site at the same time the next morning. Not completely sure why it is, but it is a good trick to have up your sleeve when you are obsessive about planning lke I am!
