Qantas LAX First Lounge

[serfty]

Technically though on one of must last visits on QF F was denied entry to CX due to priority given to CX pax, the AA F lounge had closed and it was only BA which did away with QF F dining when the JSA ended in 2013z

Yes, it is known that CX first entry at LHR can be difficult in the times before CX flights depart. Currently, 1pm-3pm after the noonish flight leaves and before the evening bank is more likely for access.
