These Airports Are Most Likely to Delay Your Trip

The airport transfer experts at Transfeero examined data from the U.S. Bureau of Transportation Statistics to determine which of the country’s 30 busiest airports have the most late departures in 2025.

The airport with the most flight delays is Dallas/Fort Worth International, with 25.42 percent of all flights pushed back this year so far. Severe thunderstorms seem to be the leading cause. Meanwhile, Denver International Airport trails behind, clocking in with 23.86 percent of flights delayed. Per KKTV11, 874 flights in and out of the hub didn’t take off or land on time on July 24 alone, with thunderstorms also being the main reason for the delays.

In third place is Ronald Reagan Washington National at 23.29 percent. The airport is known for being “overburdened,” as its main runway sees over 800 takeoffs and landings a day. That’s more than any other runway in the country.

There are plenty of things you can do when your flight is delayed—or worse, canceled. For example, many airlines have a Contract of Carriage, which may entitle you to food vouchers, discounts, refunds, or a hotel stay in the event of a flight delay caused by the airline. It’s best to read the airline’s terms and conditions when you book a flight so you can prepare for the worst.
