Chicago O’Hare International Airport recorded the highest percentage of delayed departures in 2025, with 28% of flights leaving late. Newark Liberty International Airport had the highest overall disruption rate, with 26% of flights delayed and 2.7% canceled.
Other airports with elevated delay rates included Denver International Airport (27%), Miami International Airport (26%), LaGuardia Airport (26%), Philadelphia International Airport (26%), Ronald Reagan Washington National Airport (26%), John F. Kennedy International Airport (25%), Orlando International Airport (25%) and Washington Dulles International Airport (25%).
Certain long-haul routes also stood out. The most delayed route was Chicago O’Hare to Frankfurt Airport, where 46% of departures were late. Washington Dulles to Frankfurt followed at 43%, and Miami to São Paulo Guarulhos ranked third, with 40% of flights delayed.

On the positive side, Daniel K. Inouye International Airport in Honolulu led the nation in punctuality, with 84% of departures leaving on time. Salt Lake City International Airport followed at 82%, while Los Angeles International Airport posted 80% on-time performance. San Francisco International Airport, Phoenix Sky Harbor and Minneapolis–Saint Paul International Airport also ranked among the most reliable.
The most punctual international route from the U.S. was Honolulu to Tokyo Narita, with 95% of flights departing on schedule.
Peak Disruption Months
July saw the highest disruption rate, with 31% of passengers affected, largely due to severe thunderstorms across the East Coast and Central U.S. June and December followed at 30%. A federal government shutdown in October and November also contributed to widespread delays, including temporary FAA traffic reductions.
Navigating Delays
With U.S. compensation rules largely limited to denied boarding from overbooking, travelers should carefully consider airline network strength and routing options. Larger network carriers may offer more rebooking flexibility during disruptions compared with point-to-point budget airlines.
For travelers, understanding historical delay patterns can be a valuable tool in choosing departure airports, planning connections and minimizing travel headaches.
