The future for (mixed fleet) due to 900 hour rule, is shorthaul and short longhaul.
Really? Apparently, a return to PHX for WW over MF has been "rumoured" since about September. But how much would this cost? It's a five day trip for WW - but a three day trip for MF. And the allowances for WW are much greater. ATL is a different kettle of fish - it's a 48 hour trip on both fleets - but the much prized terms and conditions for WW make it much harder to move PHX back to WW on a permanent basis - crew costs would more than double.
There are also rumours of KL moving to MF - and guess what? The box payments (?) which netted crew members £1000 for a trip wouldn't be there - it would be a 48 hour trip (£120) with onward flight to SYD codeshared to Qantas. There will be expansion eastwards in the next few years - and since new contracts will be MF, the crew costs will be low.
At the moment, large sections of MF are in furlough, due to 900 hours - and it costs BA about £1000 per month per crew member. The fact that most of the crew can't live on that salary is a matter of supreme indifference both to the company and to the union - who don't realise that part of the reason that MF aren't joining in droves is because they literally HAVE NO MONEY. The terms and conditions for WW I guess mean that they are unlikely to reach 900 hours. But any routes that the company can realistically change from long WW trips to short MF trips, without starting a strike, they will do so. Small tokens are being tossed to MF - day off after overnight back from Africa etc - but it's still going to be incredibly easy to get 900 hours flying out of them for around £16000.
