Chicago - United Airlines considers the possibility of including the long-range variant of Airbus' A321neo (A321LR) in its fleet to replace the old 757-200s on some transatlantic routes.

A321LR can be configured to accommodate 16 passengers in Business class, 72 in Premium and 90 in Economy - 178 seats in total. A denser configuration than that of the United's 757-200s (28 + 42 + 72).

United Airlines has not yet ordered an Airbus neo, even though it already operates 67 A319 (34 copies more waiting for delivery) and 99 A320. On the other hand, it expects 54 737 MAX 9 in addition to the seven that were already delivered, and 100 737 MAX 10.

American carrier's single-aisle Boeing fleet also includes 40 737-700, 141 737-800, 136 737-900ER, 56 757-200 and 21 737-300. The 757-200s are currently deployed on United's transatlantic routes to Dublin, Edinburgh, Glasgow, Lisbon, London-Heathrow, Madrid, Manchester, Porto, Reykjavik, Shannon and Stockholm in Europe.

Recall that Israel's Arkia replaced Primera Air as launch company of the A321LR after the bankruptcy of the Danish leisure operator.

To date, the A320neo's long-range variant has accumulated 120 orders from twelve operators around the world, including the leasing company ALC, TAP Air Portugal, Air Transat, Qantas for its subsidiary Jetstar, Norwegian and Air Arabia.

The A321LR also attracted the interest of WOW Air, IndiGo, JetBlue, AirAsia, and Air France among others.

Airbus is now working on a new additional version of the A321LR with more flight range, the A321XLR.
