Already 4-man Long Haul puts many pilots operating the flight into sleeping out of their own regular time zones, like the HKG-Europe or HKG-US sectors. 3-man Long haul to Oz/NZ/ANC is just as bad. Putting 3-man Long Haul to Europe/US is just a disaster waiting to happen.
I say NO to 3-man Long Haul! There is a reason why they call it LONG HAUL!
