Delta Air Lines (DL, Atlanta Hartsfield Jackson) is exercising options for 34 additional Airbus A321neo aircraft as part of its long-term fleet modernisation strategy, the company said in a press release.

Deliveries from this order are scheduled to arrive in Delta’s fleet beginning in 2029, allowing for the growth of this particular type to 189 aircraft, “making it the largest-scale fleet type in Delta’s history.”

The US carrier took delivery of its first A321-200NX, the only A321neo type it operates, in 2022, and the fleet has since expanded to 92 in service, with 97 additional firm orders, inclusive of the latest option exercise. Delta retains options for 36 additional A321neo.

This is the third aircraft order announced by Delta this year. Last month, it announced two separate orders, totalling more than sixty widebody aircraft, for the Boeing B787 as well as the A330-900N and A350-900.
