Delta Air Lines has deferred taking delivery of 10 of Airbus’s 25 A350-900 aircraft.

The delivery was planned for 2019-20 and has been delayed by two to three years with additional delivery flexibility. The airline said it plans to take delivery of five A350s in 2017.

Delta also placed a fresh order with Airbus SE for 30 A321-200s.

“These agreements better align our wide-body and narrow-body order books with our fleet replacement needs,” Gil West, Delta’s Senior Executive Vice President and Chief Operating Officer, said in a statement. “We appreciate the partnership of Airbus, Rolls-Royce and GE Aviation as we exercise what’s best for our business, our employees and our customers.”

The airline said it plans to operate its first A350 revenue flight in the fourth quarter, featuring the Delta One Suite and Premium Select cabin.

Delta’s decision follows American Airlines Group Inc saying in April that it had also delayed taking delivery of several wide-body Boeing Co and Airbus jets.

“An oversupply in the market of long-distance wide-body aircraft has led to airlines postponing deliveries,” Reuters notes, saying the moves put “a question mark on the demand for wide-body aircraft.”
