The world’s worst airports for delays and cancellations this summer

(CNN) — Anyone who has been to an airport recently can see that the demand for travel has returned in a big way. What did not return with a vengeance were the resources needed to control the oppression of air travelers.

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

The airport reported that 52.5% of its scheduled flights were delayed this summer. Toronto Pearson ranks 4th globally for flight cancellations, with 6.5% of flights canceled during that period.

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

Europe is also plagued by delays.

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

Seven of the top 10 airports in the world for delays this winter are in Europe. Frankfurt, Paris, Amsterdam and London airports are seeing the most significant delays, according to FlatAware data.

U.S. Transportation Secretary Pete Buttigieg recently told CNN that he is looking at improvements in air travel, but he still expects airlines to do better.

“Look, we count on airlines to deliver to passengers and service the tickets they sell,” Buttigieg said.
