First, Airbus announced a firm order for 100 A320neos, the aircraft maker's single-aisle competitor to Boeing's 737 MAX family, from GE Capital Aviation Services (GECAS), a division of General Electric Co.
Low-priced carrier SpiceJet on Monday said it has signed an MoU with Boeing for 40 737 MAX airplanes.
The Boeing 737 Max 10 is the latest in the 737 Max series, and promises 230 seats for the single-aisle aircraft, and a flight range of 3,215 nautical miles.
Boeing Commercial Airplanes Senior vice president (Asia Pacific and India) Dinesh Keskar said, "the additional 20 737 MAX 8s and capacity provided by these 20 new 737 MAX 10s will allow SpiceJet to offer even more passengers their award-winning onboard experience, while the aeroplane's greater efficiency will keep SpiceJet profitable".
Speaking ahead of the Paris Air Show, which starts tomorrow, boss Dennis Muilenburg said Boeing remained committed to long-term investment in the United Kingdom, regardless of the outcome of Brexit talks. Of these 220 are A320neo family aircraft including 33 A321neo.
The biennial show got underway at Le Bourget near Paris on Monday and runs until June 25. As these planes can carry more passengers, they have attracted interest from low-priced airlines as well as carriers looking to exploit their range that allows them to make flights across the Atlantic.
Airbus will also showcase its new long-haul model A350- 1000 and Boeing its 787-10 Dreamliner, while ukraine's Antonov will present its 132 D.
He said Boeing was also considering making a totally new mid-market airliner.
However, Airbus immediately hit back with an order for 100 of its popular A320neo planes from leasing company GECAS, as well as a deal for 12 A321neos with Air Lease Corporation.
After years of booming orders driven by increased air travel and more fuel-efficient planes, passenger jetmakers are bracing for a slowdown in demand while they focus on meeting tight delivery schedules and ambitious production targets.
The Paris Airshow opened under bright blue skies on Monday, with a new member of Boeing's best-selling 737 range set to vie for attention with a potentially huge order for F-35 fighter jets and a visit by French President Emmanuel Macron.
Customers will be announcing order details throughout the week, the company said in a press statement.
There will also be some 200,000 regular visitors, many of whom will come especially for spectacular displays of supersonic military hardware as fast combat planes break the sound barrier. That is in addition to the 150,000 industry professionals from 2,370 companies.
