World’s worst airports for delays and cancellations this summer

(CNN) — Anyone who’s been to an airport recently can see that demand for travel is back in a big way. What’s not back with a vengeance are the resources needed to handle the crush of air travelers.

Add summer weather to staffing issues at airports and airlines and you have a perfect storm of delays and cancellations.

A whopping 52.5% of the airport’s scheduled flights have been delayed this summer, the data shows. Toronto Pearson also ranks No. 4 for flight cancellations globally, with 6.5% of its flights canceled during that period.

The policy allows travelers to change their departing or arriving flights to Billy Bishop Toronto City Airport or to extend connection times at Toronto Pearson.

Europe is also plagued with delays

Of course, Toronto’s airport is far from alone in struggling with disruptions.

Seven of the world’s top 10 airports for delays this summer, ranked by the percentage of scheduled flights delayed, are in Europe. Airports in Frankfurt, Paris, Amsterdam and London are seeing the most significant delays, according to FlightAware data.

US Transportation Secretary Pete Buttigieg recently told CNN that he’s seeing air travel improvements, but he still expects airlines to do better.

“Look, we are counting on airlines to deliver for passengers and to be able to service the tickets that they sell,” Buttigieg said.
