Central European budget carrier Wizz Air is ordering another 10 Airbus A321s.
The jets will be delivered in 2018-19, said chief executive Jozsef Varadi, speaking during the Paris air show.
All the aircraft will be fitted with International Aero Engines V2500 powerplants.
Varadi says the jets will support the airline's ambitious growth plans, adding that the carrier aims to have a fleet of some 200 aircraft by 2023.
He says the current growth rate of some 23% amounts to inducting around 14-15 aircraft each year.
"It's a significant delivery programme," he says.
Wizz Air is an all-Airbus single-aisle operator and already has 83 A320-family jets – among them 19 A321s. Varadi says the A321 is a "traffic stimulator".
Airbus is already set to start delivering 110 A321neos to the carrier from 2019.
