Delta Air Lines has marked the latest milestone in its fleet renewal and expansion efforts with the first delivery of its newest narrowbody, the Airbus A321neo.

“The delivery of our first A321neo helps to usher in the next era of premium domestic service at Delta,” said Delta’s S.V.P. of Fleet and Tech Ops Supply Chain, Mahendra Nair.

“Not only do these aircraft offer the best customer experience in the industry, but these fuel-efficient airplanes further demonstrate our commitment to a more sustainable future.”

Delta expects to welcome 26 state-of-the-art A321neos to its fleet this year, with a total of 155 purchase commitments through 2027.

Delta’s newest fleet helps to reinforce its position as an industry leader in environmental sustainability while connecting the world. Powered by Pratt & Whitney GTF engines, t­he A321neo offers 20% better fuel efficiency over Delta’s current A321ceos.

The 194-seat airplane will include 20 domestic First Class seats, 42 Delta Comfort+ seats and 132 Main Cabin seats, all with memory-foam cushioning for improved customer comfort.

The new domestic First Class seat features more privacy, workspace and storage.

The comfortable interior features thoughtful touches throughout, and all customers will enjoy Delta’s wireless in-flight entertainment system at every seat, spacious overhead bins and access to fast-streaming WiFi and power ports.

While the latest delivery signals a new chapter, the A321neo complements an already extensive fleet of A321ceos. Once all of the A321neo orders are fulfilled, Delta’s A321 family will grow to 282 aircraft.

After Delta’s Technical Operations teams prepare the new models for service, Delta’s first A321neo is scheduled to enter into service in May.
