The Financial Post reports in its Thursday edition that WestJet's multibillion-dollar aircraft order from Boeing could face lengthy delays after a high-profile safety incident on a Boeing plane snarled the airplane's certification process. Postmedia's Matt Scace says that the Calgary-based airline is awaiting more than 65 Boeing 737 Max 10 aircraft, set to arrive by 2028. The plane has yet to receive final certification following an incident last month in which the door plug blew off a Boeing 737 Max 9 on an Alaska Airlines flight. WestJet announced in 2022 it had increased its order of Max 10s to 65 aircraft, giving the deal a $7.76-billion final valuation. Those planes cannot be delivered until they are approved by the U.S. Federal Aviation Administration, which said Jan. 24 that it would not grant any expansion in production for 737 Max planes until it completed an investigation into the Alaska Airlines incident that has increased scrutiny on Boeing's manufacturing practices. United Airlines chief executive officer Scott Kirby told CNBC on Jan. 23 that the airline is considering fleet plans without the Max 10 due to Boeing's recent fumbles, calling the Alaska Airlines incident "the straw that broke the camel's back."
