The World’s Most Unpunctual Airports

In fact, delays are one of the most annoying situations when traveling by plane. And there are many reasons why delays occur: Weather situations, crowded airspaces, or technical aircraft problems. However, besides that, airports also play a significant role in terms of delays. Moreover, when choosing the “wrong” airport, the probability of a delay can be immense.

As shown in one of our latest posts, many top airports achieve an on-time performance of >95%. Nevertheless, today we want to look at the bottom of the list: The most unpunctual airports. Therefore, we analyzed OAG data for almost 1,000 airports and their performance in April 2021.
