Hi all,

if you fly YYZ-LHR-FRA, and the YYZ-LHR segment is in J while LHR-FRA is in Y, can you use the *A lounge in LHR (not the AC arrival lounge) while waiting for the FRA connection?
The passenger has no status.
I know that generally, one can access a *A lounge before a flight in J, but I'm not sure if it's the same for after a flight in J.

Also, on the way back, assuming FRA-LHR is in Y and LHR-YYZ in J again, can one without status access the lounge in FRA?
I'm not sure if a J boarding pass of a connecting flight will allow lounge access at FRA.

Thanks in advance-
