After announcing orders for 30 incremental Airbus A321ceo aircraft just last month, Atlanta, Georgia-based Delta Air Lines has placed an order for ten more of the aircraft.

The agreement was announced today at the Paris Air Show.

Like previous Delta orders for the A321, the ten aircraft announced today are for the Current Engine Option version of the largest Airbus A320 Family member.

The airline took delivery of its first A321 in March of last year.

Delta now has ordered a total of 122 A321s, each powered by CFM56 engines from CFM International.

“The A321 is fast becoming a favourite aircraft of our customers and employees alike,” said Greg May, Delta senior vice president – supply chain management and fleet.

“Its excellent operating economics and customer capacity also make it a great fit for our US domestic network.”

All of Delta’s A321s feature fuel-saving Sharklets – lightweight composite wingtip devices that offer up to four per cent fuel-burn savings.

This environmental benefit gives airlines the option of extending their range up to 100 nautical miles/185 kilometres or increasing payload capacity by some 1,000 pounds/450 kilograms.

Many of Delta’s A321s are being delivered from the Airbus US Manufacturing Facility in Mobile, Alabama.

The airline received its first US-manufactured A321 last year. 

By the end of 2017, the Airbus facility in Mobile is expected to produce four aircraft per month, most going to Airbus’ US customers.

As of the end of May, Delta was flying a fleet of 188 Airbus aircraft, including 146 A320 Family members and 42 A330 wide-bodies.
