China Aircraft Leasing has placed an order for 40 Airbus A321neos.

The lessor states in a stock exchange disclosure that the aircraft will be delivered in stages up to 2026.

Chief executive, Mike Poon says: “We see enormous market appetite for this single-aisle aircraft with lower operational cost, and the order is in line with our portfolio strategy of investing in the most in-demand modern technology aircraft with unbeatable fuel efficiency.”

“Moreover, continuous and consistent order is the driving force behind CALC’s sustainable business growth. Not only does a strong order book strengthen the group’s ability to provide our airline clients with one-stop fleet upgrade services, it is also an important asset to reinforce our leadership in the global aviation market.”

The order was executed as a supplemental agreement to two purchase agreements signed in December 2014 and is described as an amendment to the earlier agreements.

Under the 2014 agreements, CALC placed an order with Airbus for 16 A320-200ceos, 10 A321-200ceos, and 74 A320neos, scheduled for delivery from 2016 to 2022. The aggregate list price of approximately $10.2 billion relates to the airframe, engine, as well as optional features.

The lessor has just received two Boeing 787s, purchased directly from the manufacture and the first widebody aircraft in its orderbook. These were converted from earlier orders for 737 Max aircraft and have been placed with an Asian airline, likely to be Bamboo Airways.

Cirium schedules data shows that the lessor currently manages one A321neo, among the 108 A320 family aircraft in its managed fleet. Its orderbook includes 115 A320neos and 10 A321neo.

The story has been updated with additional information from CALC’s stock exchange disclosures, regarding the delivery schedule and the nature of the transaction.
