Atlanta-based legacy carrier 
Delta Air Lines has long been the only major US airline to extensively prefer Airbus widebody aircraft to those built by US-based manufacturer Boeing. With the many ongoing issues the planemaker is having, this may be paying some dividends, with Delta seeing fewer delays in delivery timelines. The airline, which has placed an order for 44 Airbus A350-900 aircraft, of which around 34 have already been delivered, is preparing for its latest bout of A350 network expansion.
