One week after it ended, WestJet continues to feel the effects of a mechanics strike that nearly shut down the airline’s network for 29 hours.

The two-day work stoppage that began on June 28 forced the airline to cancel more than 1,000 flights before the end of the Canada Day long weekend, one of the busiest travel windows of the year.

The fallout continued well into last week, as WestJet called off 100 trips on Friday and Saturday as well as at least 31 more on Sunday, according to tracking service FlightAware. Figures from the airline suggest at least 170,000 passengers have been affected.
