Canadian airline Westjet has ordered 42 Boeing 737 Max-10s. The company also secured options for 22 more copies. With the additional aircraft, the carrier wants to drive expansion.

“The 737-10 will play a key role with one of the lowest cost per seat among medium-haul airliners. This will further our low-cost positioning and affordability for Canadians,” said Alexis von Hoensbroech, WestJet Group Chief Executive Officer. "In addition, the 737-10, with its lower fuel consumption and reduced emissions, will further improve our fleet's environmental footprint."

Since starting the company with three 737s in 1996, WestJet has grown its Boeing fleet to more than 100 aircraft, including the 737-8 and 787 Dreamliner. Including the 737-10, the Calgary-based airline has more than 60 firm orders for the 737 MAX family.

"The 737-10 will provide WestJet with additional capacity and unmatched efficiency as the airline expands its route network in Canada and around the world," said Stan Deal, President and CEO of Boeing Commercial Airplanes. "We are proud that WestJet has recognized the value of the 737 MAX family and is deploying the 737-10 to complement the 737-8 to achieve superior capability, flexibility and enhanced sustainability."
