Mainline SOs with different payscales in the same cockpit.
I can see QF arguing in court that an A-320 job in one state is different to a 737 job in a different state because there are lots of differences to point to, ( lots that the lawyers can bring up) but I can’t imagine them getting a win with SO’s on the same routes in the same metal with the same training departments and the same pay master, carrying the same pax. That really is the same job with different pay.
