No need to argue.
The A330-300 configured in NW
's configuration probably is capable of 5300 nm with pax and bags, ISA, and no wind. I'd also be surprised if the NWA.com numbers are right, since NW
press releases say the A330-200s they ordered can only do 5400 nm out of the 332's max of 6650.
wants to haul a lot of cargo, which NW
does like to do, they'll get less than that.
There's no reason the 333 couldn't do it, I'm sure it could. But the 332 could certainly do it better.
All that aside, everything I've heard here, and from those no longer with us, is that the route will get the 332.
