Air Canada is reporting a strong start to its summer travel season.

The airline says around 540, 000 customers flew with the carrier between May 19 and 22.

“Our mainline aircraft was 95 percent full on Friday, yet we achieved a flight completion ratio of 98.7 percent and a solid on-time performance that reached 90 percent Sunday morning. Although system-wide weather was favourable, we did face several challenges, including wildfires in Western Canada, weather disruptions in the southern U.S. and even a volcano in Mexico that all affected flights,” said Kevin O’Connor, Senior Vice President, of Global Airports and Operational Control at Air Canada.

He adds, “While sustained high passenger loads of the season are yet to fully arrive, our success during the first holiday weekend gives us added confidence that we are ready to perform well this summer.”
