Some WestJet flights still being cancelled Tuesday as airline ramps up after strike

Flight disruptions continue at WestJet as the airline ramps up following a brief work stoppage over the long weekend.

Data from aviation analytics company Cirium shows more than 300 WestJet flights were cancelled Monday, or around 62 per cent of those scheduled, despite the carrier reaching a tentative deal early that morning with the union representing its 4,400 flight attendants.

It says 16 flights scheduled for Tuesday had been cancelled, as of around 11 a.m. ET.

WestJet says a full return to normal operations will take time as the airline resumes flying and repositions its aircraft and crews.
