US lessor GECAS has increased its commitment to the Airbus A321neo by converting orders for 45 A320neo jets.
Airbus's latest backlog revision shows the company's orders for the largest variant of the family has increased from 59 to 104 aircraft.
The conversion brings its A320neo commitment down to 116 aircraft – of which 35 have been delivered – from the previous 161.
GECAS has also received 13 A321neos.
The lessor has previously expressed interest in the longer-range A321XLR, unveiled at the Paris air show, but there is no indication that the swap includes any commitment to the XLR.
GECAS's conversion involves part of a batch of 100 A320neos originally ordered in June 2017.
It becomes one of the largest customers for the A321neo as a result of the conversion, behind such companies as AirAsia, Wizz Air, IndiGo, VietJet, American Airlines and Air Lease.
Spanish budget airline Vueling has also newly converted two A320neos to A321neos, giving it orders for 14.
Airbus has secured total orders for 2,762 A321neos. These include 15 A321XLRs newly ordered during August.
