Can QR code share on BA flights to the main Australian cities if it has no more capacity under the bilateral ? Not sure if the bilateral only applies to operating your own flights or all flights, including codeshares.

Qantas in its recent results again mentioned the direct LHR-PER flight is by far the most profitable on the network, with almost all of pax originating in PER (the flight originates in MEL) and most of the J cabin full of travellers from the mining companies in Perth, all of which would have corporate deals with BA too (BHP, Rio, S32 etc). I wonder if BA has considered this.
