If all 4 of you are on the same PNR then yes, they will only clear you if 4 C seats open up at the same time. On a busy-ish route like DFW-LHR, with only 15 seats left in J, it will be standard AA protocol to not release any C space until around 48-24 hrs before the flight.
Good to know. If I could snag a couple 48 hrs in advance, 2 at airport would be a lot more likely. I've had 3 C clear DFW-LHR at airport before, but not 4. No C have opened from the time I purchased the tickets. Only one flight the following week has 7 C from 26 J available. So seems kind of tight.
