I doubt that it is all equal and that some airlines are more impacted than others. Can't imagine many wanting to make a trip from EU into London to purchase a QF ex-LHR ticket
If one or more airline wanted it, with this not being a published benefit , is an easy change to make and better for the alliance than an airline quitting
