Southwest Airlines has placed an order for 108 additional Boeing 737-7s, bringing its total orders to more than 500 737 MAX jets, including more than 300 orders for the 737-7.

The additional Boeing aircraft will support Southwest’s modernisation strategy, providing flexibility as the low-fare carrier expands its fleet. The new 737-7 aircraft will join the carrier’s all-Boeing-737 fleet following certification.

“We have a long history with Boeing, dating back more than 50 years to the day we commenced service with three Boeing 737 aircraft serving three cities,” said Bob Jordan, President and Chief Executive Officer of Southwest Airlines. “They’re part of our history and part of our future as we continue to recognise the many efficiencies and cost savings of a single fleet.”

“With the world’s largest all-Boeing, all-737 fleet, Southwest is counting on the exceptional efficiency and reliability of the 737 MAX family,” said Stan Deal, President and CEO of Boeing Commercial Airplanes. “The 737-7 is pivotal to Southwest’s long-term fleet modernisation strategy, and we are honoured to have the airline’s continued trust in us to deliver its future fleet.”
