To the OP,
I'm with you!! I too am looking for the end of November at our UAL flight is gradually creeping down, while AA has not budged. However if we want to go the following week AA is much cheaper than UAL
I am currently sitting on a $267 flight from ORD to MCO leaving the Sunday after Thanksgiving. I am hoping

that the Sunday leg of the trip will come down a little (it is priced at $151), but I am not overly optimistic at this point because of the day.
Good luck!!
