I looked on Plane finders website ( a good and detailed site for tracking fleets) and see that Delta is showing just one A350XWB on order. Does anybody know if this is correct as it certainly does not make sense to me.
No, they have a total of 25 on order. Five are due to be delivered by the end of this year, and at least ten, originally due to be delivered 2019-2020, have been deferred. http://www.reuters.com/article/us-delta-air-orders-idUSKBN1871OK
