Indian low-priced carrier SpiceJet has committed to buy the new 737 MAX 10 planes from Boeing Co, the companies said, becoming an inaugural customer for an aircraft created to blunt strong sales of rival planemaker Airbus' A321neo.
"Adding the 737 MAX 10 gives our customers the most flexibility in the market, providing their fleets the range capability, fuel efficiency and unsurpassed reliability that the 737 MAX family is widely known for".
The agreement, valued at approximately Dollars 4.74 billion at current list prices, is split evenly between 20 new orders for the 737 MAX 10 and conversions of 20 of the low-priced carrier's 737 MAX 8 airplanes of its current order to 737 MAX 10s.
A large order for 100 A320neos, the latest version of Airbus's single aisle A320 series, was placed by leasing company GECAS and will be worth a total of £1.2bn to the United Kingdom, which manufactures wings for the A320 family.
The Chicago-based company projects that the Max 9 and 10 will together capture 25 percent to 30 percent of 737 sales over the next 20 years.
The 737 MAX continues to be the fastest-selling airplane in Boeing history, accumulating more than 3,700 orders to date.
GECAS also converted an existing 737 order for 20 planes to the new model and Europe's largest tour operator TUI Group (TUIGn.DE) did likewise for 18 aircraft.
Industry sources said Airbus would also soon announce a large order for its A321neo, as well as one for 10 of its A350-900 wide-body jets.
"GECAS' renewed order of our best-selling A320neo aircraft, underscores the continuing strong market demand for these fuel-efficient aircraft", said Fabrice Brégier, Airbus COO and president, Commercial Aircraft.
Demand for passenger planes may be faltering but interest in military aircraft is picking up.
When the stealthy hi-tech F-35 fighter jet tears through Paris skies on its first ever acrobatic displays this week, the jet will also be sending a message: North Atlantic Treaty Organisation allies, the United States is still on your side.
That would be the biggest deal yet for the stealth warplane, which is making its Paris debut this week.
His arrival is expected to be followed by a flypast by the world's largest passenger plane, the Airbus A380, and France's aerial display team.
Airbus's chief salesman John Leahy said in Mexico this month that the new Boeing plane looks "very marginal" and risks compromising range and performance for "a few extra seats".
While superjumbos like the A380 - four engine, double-decker giants - were once seen as the future of air travel, many airlines have instead come to prefer cheaper and more agile planes.
