Airbus announced it had won orders for 421 aircraft collectively worth $16.3 billion at this week’s Paris air show, as well as other commitments worth $40.7 billion.

"We had again a very successful Paris Air Show, we received orders and commitments for 421 aircraft worth $57 billion," Airbus Group’s plane manufacturing division CEO Fabrice Bregier told reporters on Thursday, Reuters reported. "This was higher than I expected."

Out of the orders worth $16.3 billion, European low-cost carrier Wizz Air signed a provisional deal ordering 110 Airbus 321neo planes from the aviation giant, which would net over $12.5 billion at list prices.

Wizz Air, which focuses on central and eastern Europe, still needs to finalize the deal with its board. Under the company's terms, deliveries of the A321neo planes are scheduled to start in 2019. The memo also gives the carrier purchasing rights for another 90 A321neo aircraft in the future.

Wizz Air CEO József Váradi said: “We looked at different options for this order but Airbus came in with the best overall mix of aircraft, cost efficiency, support and price, so it made sense for us to continue our long relationship with them as we continue to expand our market reach across and beyond Europe,” according to the Financial Times.

Wizz Air currently operates 61 Airbus A320 aircraft across 380 routes from 22 bases.
