Great deal mkmommy! I was watching all day too. This morning, Delta released at $385 so we purchased as AC and United are over $500. But we had until midnight to cancel. I was constantly watching AA, and later in afternoon, I noticed they started adding regular flights slowly, one at a time (as opposed to just business cost). So....we ended up booking the flight 24 hrs after yours for similar price (267) and cancelling the Delta. I'm sure the fact that you're leaving on a Thursday helps with crowds. With a 5 day cruise, then you'll be even more flexible with your return flight. Hopefully return will be good luck too.
