Apologies, when I was online "mainline" referred to 'old contracts pre-casuals. And fleet was SH (734,738,76RR 76GE, A332, A333) or LH (767, 747, A330) this was pre A380 though so I guess that all went out at the same time.
they definitely won't hire onto old contracts. Why would they when they've gotten crew at less pay for more than a decade? Besides, the FAAA would have kittens and rightly so bc all those long haul crew on those contracts were made redundant back then
