The itinerary is 4699-4805 on the 2nd of october then 4805-4665 on the 5th of October. Both 4699 and 4665 have availability for J just thought they might be swapping another plane and didn't want to sell me the revised ticket. I'm on a Q fare outbound and N fare return. I was given a fee a week ago to revise the itinerary online but since then it gives me an error message and said to call reservations. Wondering if this has anything to do with the US AA merger.
