Airbus’s order surge at the Paris air show has driven the Airbus A320NEO (new engine option) backlog to 1029 orders and commitments.

The company secured 730 orders overall so far at the Paris air show, valued at $72 billion, says John Leahy, Airbus COO for customers. That does not include the 180 sold to Indigo, which had been previously announced.

This year was “the best air show ever for Airbus in terms of aircraft numbers sold,” says Tom Enders, Airbus CEO. Most of the 700 deals are firm orders, he says, valued at over $70 billion.

“I was pretty much amazed that we sold that many aircraft here,” Enders says of the A320NEO.

Leahy says more deals are planned. For instance, Alafco, which signed for 30 A320NEOs.

That is having Airbus looking at further ramp-ups for single-aisle in particular. “We will investigate if we can go considerably higher,” Enders says. Airbus has a few production slots for standard A320s free in 2014 and NEOs in 2018/19, depending on the turnover from standards to NEOs. A350 production is sold out until about 2018/19 and the A330 until 2013/14.

Highlights also include the first A319NEO order and the launch of the winglet retrofit program for narrowbodies as part of a deal with JetBlue.

Airbus has also secured an agreement for 10 A380s with an unannounced customer, likely Hong Kong Airlines which is also an unannounced customer for Boeing 747-8s.
