The best thing for BA pax
The best thing for BA pax about this divorce from the Aussies is that BA have a real opportunity to restore REAL service in its routes to Aus.
For instance, before Qantas took over, arriving at BA's check-in at Changi was a real pleasure. Ishahak and his staff would do their best to make the check-in pleasant, and quick, and he knew his regulars.
Qantas got hold of it and ever since then pax are just SLF.
Also, as many (but not all) Qantas staff were entitlement driven, all the available upgrades went to Qantas staff. Prior to Qantas, an upgrade was a remote possibility. Once Qantas took over, then Qantas staff received all the upgrades........
