Hotter air, shifting wind patterns, and increasing storm activity complicate the takeoff and landing processes, while rising seas and shrinking coastlines subject coastal airports to more frequent flooding.

Weather-related flight delays have increased in tandem with climate change, with some smaller airports reporting double-digit growth in weather-related delay activity. A closer look at data from the Bureau of Transportation Statistics reveals the airports where weather-related delays have increased the most since 2018.
To determine the airports where extreme weather is causing more delay activity, Climate Crisis 247 reviewed data on airport departures from the U.S. Bureau of Transportation Statistics. Airports were ranked based on the percentage-point change in weather-related departure delay activity as a share of all departure delay activity from 2018 to 2024. Delay activity is measured in total minutes of flight delay and is reported by cause by airline carriers. Only airports with at least 4,000 departing flights in 2024 were considered. Data on 2024 flights is through September 2024.
