Why Don’t Any US Airlines Fly The Airbus A350-1000?

Looking at the fleets of the United States ‘Big Three’ legacy carriers, one aircraft remains missing: theAirbus A350-1000. However, this won’t be the case for long. Currently, Delta Air Lines, based out of Hartsfield–Jackson Atlanta International Airport (ATL), is the only airline in the United States, and North America for that matter, to operate the Airbus A350 family of aircraft, albeit the A350-900 model.
