Looking to arrive on BA to T7 at 8:30pm and then take an AA domestic flight from T8 at 9:30pm.
Both will be in J class but not one ticket.
The domestic leg is transcontinental flagship business (JFK to LAX)
I have Global Entry and carry on baggage only.

Any chance this is doable?
I've checked on Flightaware and it seems the BA flights have been getting in around 745pm actually.
