All really appreciated. Many thanks.
Edit: BTW did the OP's situation - AS flights - get a consideration, do you know? Not his specific one, but AS flight gets etc?
I am keen to find out about the same thing too!
Planning a trip to YVR which involves 5hrs of ground time at LAX before catching a WJ (QF codeshare) flight. Would seriously benefit from some lounge access (as a QP) to kill time.
