WestJet could face costly delivery delays due to panel blowout on Boeing plane

WestJet is facing indefinite delays on dozens of new aircraft deliveries after a panel blowout on a Boeing 737 Max plane last month that prompted a halt to production expansion at the U.S. aircraft maker.

The Calgary-based carrier bought 42 Boeing 737 Max 10 jetliners in 2022, with options for 22 more — on top of nearly two dozen earlier Max orders still in the pipeline.

The multibillion-dollar deals were slated to bolster WestJet's fleet by at least 65 planes — 50 of them Max 10s — by 2029 in a move the airline called a "game-changer" that would reduce fuel costs and "underpin" its growth.

However, the Max 10 has yet to receive final certification and, after the panel incident, U.S. regulators said they would halt production expansion at Boeing until a full investigation was complete — a process that could take over a year.

The U.S. Federal Aviation Administration temporarily grounded all 737 Max 9s for inspection and launched a probe after a panel known as a door plug tore away from the fuselage of an Alaska Airlines plane while in flight on Jan. 5, leaving a refrigerator-sized hole in the cabin wall and prompting an emergency landing.

WestJet said it could handle the production turbulence.

"We continue to work closely with Boeing on all aspects of aircraft delivery and timelines. We believe our order book and fleet planning have the built-in flexibility to support WestJet's growth plans," spokeswoman Madison Kruger said in an email.

The Max 10 is the largest plane in the latest line of 737s and offers 20 per cent fewer carbon emissions per passenger than the previous generation. Fleet rejuvenation is essential to ensure efficiency, bringing down costs — jet fuel and labour are airlines' two biggest expenses — and showing a commitment to green targets.

"The ability of WestJet to do that is compromised by Boeing," said John Gradek, who teaches aviation management at McGill University.

"The older the fleet becomes, the more expensive and the less efficient its becomes," he said.

"If that airplane isn't going to see the light of day for years — if ever — because of what's going on, the plans that WestJet has for fleet renewal are going to be in jeopardy."

The 65 new aircraft ordered by WestJet amount to nearly 40 per cent of its current fleet, according to Airfleets.net. Many of them would likely replace some of the 88 airliners from the previous generation of 737 planes over time.

The list price of the 42 Max 10s ordered in 2022 totalled $7.6 billion, though large purchases typically come with major discounts.

At the time, both Boeing and WestJet stressed the importance of the deal.
