All planes, including Boeing, undergo comprehensive safety checks involving pre-flight inspections, maintenance programs and regulatory oversight.

The crash happened just weeks after the company cut a deal with the U.S. government to avoid taking criminal responsibility for a pair of deadly crashes in 2018 and 2019.

WestJet has confirmed to Airways that the variants ordered include both the Boeing 737-8 and 737-10 aircraft, adding these to an outstanding backlog for 12 Boeing 737-8 and 54 737-10 aircraft with options for 22 more. The carrier also operates 36 737-700s, 55 737-800s, and seven 787-9 Dreamliners in its mainline fleet.
