I am gonna guess they answer is no. But, here goes.

Flying internal with AA to DFW then connecting to BA First to London. Ticketed separately so I know I have to collect my baggage and recheck. I’ve a 6 hour layover. Could I, on arrival go to the lounge and get lunch at flagship first dining, then go collect my bags before checking in? Trying to avoid a long wait landside before BA check in opens.

I’ll already be checked in for the BA flight so there’s nothing to stop me going to the Admirals Club, but the concern is what happen to my bags.
