Canadian leisure carrier Air Transat is to lease 10 long-range Airbus A321LRs from AerCap.
The single-aisle aircraft will be taken on 12-year terms, says the carrier, and replace its twin-aisle Airbus A310s.
Air Transat has not indicated an engine selection for the twinjets.
But it will take delivery of the aircraft from spring 2019 until autumn 2020.
Air Transat will configure the aircraft with 200 seats in two classes.
Chief executive Jean-Marc Eustache says the A321LRs will "perfectly complete" the airline's fleet, which also includes Airbus A330s and Boeing 737s.
