United Airlines (UA, Chicago O'Hare) is evaluating adding A321neo(LR) aircraft to replace the ageing B757-200s on select transatlantic services, IBA Group has said.

As reported by AIN Online, the American carrier is reportedly studying equipping the newest generation Airbus narrowbody with 178 seats, including 16 in the business class, 72 in premium economy, and 90 in economy. That would mark a slight upgauge from the 169-seater B757s.

In terms of its narrowbody fleet, United currently operates sixty-seven A319-100s, ninety-nine A320-200s, forty B737-700s, 141 B737-800s, twelve B737-900s, 136 B737-900(ER)s, seven B737-9s, fifty-six B757-200s (including forty-one configured for transatlantic routes), and twenty-one B757-300s.

The carrier also has a further twenty-eight B737-9s and 100 B737-10s on order directly with Boeing. It has yet to commit to any A320neo Family units.

Other airlines which study using A321neo(LR)s for transatlantic routes include Air Transat, Aer Lingus, Norwegian, WOW air, and TAP Air Portugal. jetBlue Airways is also widely expected to take some units of the type as a part of its order for eighty-five A321neo.

At present, United uses B757-200s to serve Dublin Int'l, Edinburgh, Glasgow Int'l, Lisbon, London Heathrow, Madrid Barajas, Manchester Int'l, Porto, Reykjavik Keflavik, Shannon, and Stockholm Arlanda in Europe.
