PARIS (AP) — Boeing flew past Airbus in the race for plane orders at this year's Paris Air Show, thanks to a surge in interest in the newest version of the 737.

Airbus signed deals with AirAsia, and privately-owned Iranian carriers Zagros Airlines and Iran Airtour.

United Airlines executive vice-president and chief financial officerAndrew Levy said: "The 737 MAX 10 will enable us to continue using larger and more efficient aircraft within our domestic network and better meet the needs of our customers today and into the future".

Overall, the numbers were still impressive for a show where analysts expected muted demand.

Fortunes rise and fall at the Paris Air Show.

He said Clark was interested in the updates Airbus is proposing - including the ability to add 80 seats without reducing comfort and greater fuel economy - that will make the plane cheaper to operate for airlines. "This is one week's worth of commitments", he told Reuters.While he did not expect the MAX 10 to be a viable competitor to the A321, Leahy said its launch could result in price pressure. The aircraft lessor's CEO John Plueger said "With these additional 12 units, ALC's growing 737 MAX order book now stands at 130 aircraft - and we are placing them rapidly". "We had expected they would have had a bigger launch on the 737 MAX 10, not quite as many conversions, more incremental orders".

The A321 is larger than any member of the 737 family, a gap that the MAX 10 is meant to close.
