PARIS, June 2 (Xinhua) -- Delta Air Lines, a major U.S. airline carrier, will expand its A320 Family with an order for 15 A321 aircraft to offset jet retirements, european plane maker Airbus group said on Monday.
Delta Air Lines currently operates a large fleet of Airbus aircraft, including 126 A320 Family and 32 A330 aircraft. The new acquisition of the airline brings its total backlog to 45 single-aisle Airbus A321 and 10 wide-body Airbus A330 aircraft.
The newly ordered A321 aircraft are scheduled for delivery starting 2018, said Airbus in a statement.
"The A321's economic efficiency ... will enhance profitability, customer satisfaction, and shareholder value for Delta," said Nathaniel Pieper, Delta's vice president of Fleet Strategy and Transactions.
Many of Delta's A321s will be delivered from Airbus' brand-new A320 Family assembly line, currently under construction in Mobile, Alabama. By 2017, the Mobile facility is expected to produce four aircraft per month, according to the statement.
According to Airbus, all of Delta's A321 aircraft will feature fuel saving.
