International Airlines Group (IAG) on Tuesday signed a firm order for 14 A321XLRs, eight of which it plans to place with its Iberia subsidiary and six with Aer Lingus. The aircraft will allow Aer Lingus to launch new routes beyond the U.S. East Coast and Canada. For Iberia, the new aircraft type will allow it to open new transatlantic destinations and increase frequencies in key markets.

IAG, the parent company of leading airlines also including British Airways, Level and Vueling, ranks as one of Airbus’s largest customers and this agreement will take the overall order from the group to 530 aircraft. IAG airlines combined operate one of the world’s largest Airbus fleets, consisting of more than 400 aircraft.
