Mexican low-cost carrier Volaris (Y4) has signed a memorandum of understanding (MOU) with Airbus for 44 A320 aircraft, comprising 30 A320neos and 14 A320 family aircraft.

Y4 is the first Mexican airline to order the A320neo, which will be used to continue the airline’s expansion into the US and renew its fleet, Airbus said. The carrier will announce its engine selection at a later date.

Y4, which launched in 2006, operates 33 Airbus aircraft and has a backlog of 15 more, Airbus said.

“Fuel efficiency and reliability are critical to keeping Volaris among the top low-cost carriers in Mexico,” said Volaris CEO Enrique Beltranena. “These new A320s will allow us to maintain the youngest fleet in the country, while further improving our environmental performance,” he said.
