Delta Air Lines (DL, Atlanta Hartsfield Jackson) has placed a firm order with Airbus (AIB, Toulouse Blagnac) for fifty new widebody aircraft entailing twenty-five A350-900s and twenty-five A330-900neo. The incoming jets will replace the carrier's outgoing B747-400 and B767-300(ER) fleets set to begin leaving in 2017 and 2019 respectively.

Rolls-Royce Trent 7000 engines will power the Airbus A330neo aircraft and Trent XWB engines will power Airbus A350 XWB aircraft.

The Airbus A350-900s will begin arriving in the second quarter of 2017 and will primarily operate on long-range routes between the US and Asia while the A330-900neo, scheduled to enter the Delta fleet in 2019, will be deployed on medium-haul transatlantic flights as well as select routes connecting the US West Coast and Asia.

With the addition to this order, Delta's Airbus order backlog now totals 105 aircraft including ten A330-300s and forty-five A321ceo aircraft.
