I am en route to JFK to fly to new 77W to GRU. We are arriving on a separate itinerary though on AA. I tried asking at the club at DFW if they could check us in but she said all she could was print our itinerary out, that they "took that away from her". Where at the AA terminal at JFK can we check in for our onward flight, without reclearing security? I tried checking in online but because they have to check visa validity it wouldn't allow us. I don't want to go through security again, I want to spend time in the FL lounge! Are there ticket desks somewhere I am not thinking of that can help, inside security?
