Canadian airlines and airports claimed top spots in flight delays over the July long weekend, notching more than nearly any other around the world.

Air Canada ranked No. 1 in delays on Saturday and Sunday as two-thirds of its flights – 717 trips in total – took off late, according to tracking service FlightAware. It was more than 14 percentage points above the three carriers tied for second place.

Jazz Aviation – a Halifax-based company that provides regional service for Air Canada – and the lower-cost Air Canada Rouge both saw 53 per cent of flights delayed, putting them in the No. 2 spot alongside Greek regional airline Olympic Air.

On Saturday, WestJet and budget subsidiary Swoop placed third and fourth.

On the airport front, Toronto’s Pearson claimed the No. 2 spot Sunday after 53 per cent of departures were held up, below only Guangzhou’s main airport in China. Pearson beat out Charles de Gaulle airport in Paris and Frankfurt Airport in Germany.

Montreal’s airport placed sixth Sunday at 43 per cent of takeoffs delayed, on par with London’s Heathrow, according to FlightAware figures.
