Ollie, you’re right in a way,
Narrowbody aircraft doing 10/11hr sectors is a very new thing, and previous contracts don’t account for this type of flying. The company is quite determined to fly these thinner long haul routes on the aircraft.
Now if pilots are under the impression they’re going to stop the company from deploying the 321 on 10/11hr sectors, or have it replaced by a LH widebody or have the 321 flown under the LH contract they’re quite mistaken.
If they don’t want the flying then it will go elsewhere. It isn’t even like the A350 EBA where they were looking at forming a new contract company to outsource flying to, they already have 3 existing A320/321 operators in the group. It would be simple and those operators would be flying those 10/11hr routes with fewer protections than if they came to SH under an FRMS.
So firstly you need to accept that this flying is only going to be done on the SH contract, then you need to think about how to do it with suitable rostering. The 737 in recent times, a far less comfortable aircraft, has done 5.5hr back of the clock flights. Are current competitors flying 7-8hr sectors back of the clock from Asia to Australia 2 crew? For sectors 9-10 hrs is a 3rd crew with a business seat rest being proposed? Valid questions on how to formulate a plan to do what is essentially new flying.
And don’t forget these aircraft will be primarily 737 replacements, so the vast majority of it will initially be domestic flying. Even when the full fleet size is reached I would guess international sectors would make up no more than 15% of total flights.
