Hong Kong-based lessor China Aircraft Leasing Group (CALC) has signed a purchase agreement for 15 A320neos, valued at $1.63 billion at list prices. The aircraft are scheduled for delivery from 2022-2023.

The transaction follows an order for 50 A320neos in late December 2017.

CALC’s total order book with Airbus will increase to 217 aircraft plus the 15 A320neos.

CALC currently operates a total fleet of 107 aircraft; its backlog after the new order stands at 193 aircraft, comprising 143 Airbus and 50 Boeing aircraft.

Separately, earlier this week the lessor signed a purchase and leaseback agreement with PDP financing with the Latin America LCC group Viva Air for five A320-200ceo family aircraft, which are scheduled for delivery from 2018-2019.
