Re: Would A321XLR open the door for non-stops between US west coast and CTS?

The range of Boeing 707-320C is quoted as 5000 nm with 151,5 t MTOW and payload of 141 passengers and baggage (18J+123Y) DC-8-62 range is quoted as 5200 nm with 158,8 t MTOW and 189 passengers. So how does A321XLR compare to 707 and DC-8-62 in more details? Which transpacific lines got served by 707...

Re: Would A321XLR open the door for non-stops between US west coast and CTS?

With the nominal range of 4700 nm, what would be the practical range upwind? YVR-NRT is 4061 nm, YVR-CTS 3726 nm. Is it feasible westbound? The A321XLR should easily be able to fly 4000nm into the strongest headwinds. It should be able to do most routes up to 4300nm From Hawaii the XLR could fly to...

Re: Would A321XLR open the door for non-stops between US west coast and CTS?

Indeed it seems this aircraft's range unlocks those routes, but this is actually not true. This range would be in still air, but the air isn't still. Far from it. In the north Pacific you'd be flying against some of the strongest winds on the planet, which would greatly reduce the aircraft range. I...

Concorde as is is problematic. Short range and requires a smooth (and long!) runway. Oh, and it is smaller than Constellation.
So basically a widebody.
Two engines are common. So are four engines (A340, Il-96).
The only widebodies to catch eye, besides the already mentioned A380, would be trijets.
