JFK to LHR on AA104 arriving T3 - Business class
Connecting to BA6745 Departing T5 possibly: Business class
Currently scheduled to be a 5hr layover.
I'm am currently thinking airside bus from T3-T5. Clearing security which will take an hour. Then finding one of the lounges until the BA flight.
There really isn't much else to ponder, as noted above you'll arrive into T3, just follow purple signs to flight connections and take the bus to T5, clear security then head to one of the 2 BA business lounges in T5A.
LHR-BSL will almost assuredly depart from T5A; all T5A gates are at most a 5-6 min walk from either of the lounges there. On the off chance it departs from T5B or C then just take the elevators down to the bottom and walk over in the tunnel if you like walking (that's what I always do for T5B/C departures).
