Jet fuel prices have gone up exponentially over the past month. This is one of the largest expenses airlines have, and the US airlines don't hedge their fuel costs. The price of jet fuel is only going to continue going up.
This doesn't mean there won't be some deals or fares lower than what someone previously paid, but the main direction is up (by a lot). I think some people are in for a shock when they see how expensive airfare is going to start getting over the next month.
