A larger capacity Boeing 737 MAX variant was unveiled today at the Paris Air Show.

The 737 MAX 10, due to be available from 2020, will be capable of carrying up to 230 passengers, 12 more seats than the MAX 9.

The aircraft will also be 66 inches longer than the MAX 9 model.

The additional capacity couple with advanced technology winglets and an extended range will make it the highest efficiency single-aisle aircraft, the US manufacturer claims.

The 737 MAX 10 continues the MAX family’s range advantage over competing models and will deliver five per cent lower trip costs and five per cent lower seat-mile costs, according to Boeing.

The new aircraft has attracted more than 240 orders from over ten customers.

Boeing Commercial Airplanes president and CEO Kevin McAllister saids: “The 737 MAX 10 extends the competitive advantage of the 737 MAX family and we’re honoured that so many customers across the world have embraced the outstanding value it will bring to their fleets.

“Airlines wanted a larger, better option in the large single-aisle segment with the operating advantages of the 737 MAX family.

“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.”
