Upgraded Points
Highlights both airports and airlines most susceptible to weather-related delays

Upgraded Points' newest survey reveals the U.S. airports most impacted by weather-related delays, based on historical data from the Bureau of Transportation Statistics (BTS). Examining delays from November through January, the study helps holiday travelers prepare for potential weather disruptions and identifies the airlines and airports most prone to delays due to Mother Nature.

 

Study Methodology

The survey analyzed weather-related flight delays at the 60 busiest U.S. airports from BTS data, focusing on the holiday period from November to January – with averages taken from data between January 2019 and July 2024 (2020 data was excluded due to COVID-19 disruptions). Year-round delays and the 10 largest U.S. airlines were also examined to find the most weather-affected carriers seasonally and throughout the year. Airport rankings are based on FAA enplanement data, and airline rankings are based on capacity data from OAG.
