CALGARY — WestJet continues to feel the effects of a two-day plane mechanics strike that nearly shut down theairline’s network for 29 hours over the Canada Day long weekend and cost it millions of dollars.

The work stoppage that began on June 28 forced the airline to cancel more than 1,050 flights during one of the busiest travel windows of the year.

Fallout from the unexpected job action continued well into last week, as WestJet called off 244 trips Tuesday through Saturday as well as at least 32 more on Sunday, according to tracking service FlightAware.

Figures from the airline suggest at least 170,000 passengers have been affected.

The task of fully resuming flights by a nearly grounded fleet of 180 planes across more than 175 destinations is complex, costly and time-consuming.

WestJet said it was on track to revamp operations promptly.

“We sincerely apologize to all guests affected by the strike,” said spokeswoman Madison Kruger. “Our teams across WestJet are working diligently to support all impacted guests as quickly as possible.”

One travel agency owner is calling on the federal government and the Canadian Transportation Agency to hold the carrier to account.

WestJet has said it offered guests a refund if they couldn’t be rebooked within two days of the scheduled departure time. The company must respond to expense and compensation claims within 30 days, it added.

“Compensation for hotels and meals is not required under the (Air Passengers Protection Regulations) for situations outside of a carrier’s control,” Kruger added.

Whether cancellations made days after the strike ended are caused by factors outside of WestJet’s control remains in dispute, with the company on one side and advocates on the other.

Small claims court is one route to possible reimbursement should the airline reject a request, including for costs incurred from a last-minute flight — with WestJet or  another airline — said Gabor Lukacs, president of the Air Passenger Rights advocacy group. Customers can also file a complaint with the transportation agency.

A ‘cancel fee’ that WestJet highlighted in emails informing travellers their flight had been called off has also raised eyebrows. WestJet did not respond to questions about the charge.
