The prices change, because Orbitz, etc., have a database that searches these airline's fares. It is not because they communicate with JetBlue, and the other airlines, daily, to update fares. I am sure that they have some kind of agreement with the airlines to do this, but that doesn't mean the airlines are responsible for advertisements, and other problems that arise with these low fare websites. They are third party companies, just like a travel agent, and in fact, the airlines aren't even responsible for problems with reservations, that were reserved, using these websites. Reading all of the "small print" and terms of service information on these "low fare" websites, will tell you all of that. Did you know that seat assignments are not even guaranteed, when you purchase through these low fare websites, for example. --- there is always a catch when it comes to finding the cheapest possible tickets. It is better to purchase the tickets directly from the airline, itself, even if it means paying a little more.

I certainly do not know the situation fully, but I would be willing to guarantee that JetBlue/Orbitz, sold several tickets that day for the advertised $80, but since only a select few of seats were sold at that price, the price had gone up, by the time you tried to purchase one.

I agree that the advertisement should have been pulled off of the website, as soon as they sold out, and that part you may want to take up with Orbitz, and JetBlue. But I doubt JetBlue keeps constant tabs on what Orbitz, and these other websites are doing, and advertising, on a daily basis.
