Air travelers faced more disruptions this summer than in recent years, with U.S. carriers canceling flights at the highest rate since 2022. Data from FlightAware shows cancellations rose about 15 percent compared with the prior summer, leaving many passengers stranded or delayed during peak travel months. The trend continued into the fall, with an air traffic control outage earlier this month grounding more than 1,000 flights on the East Coast. ([1])
Why Cancellations Rose Sharply
No single cause explains the increase. Winter storms in January created major problems for carriers such as American Airlines, while runway work at hubs including San Francisco International Airport added further strain. Congestion around New York and Washington continued to slow operations, and routine summer thunderstorms hit already full schedules hard.
Through the first nine months of the year, roughly 2 percent of all U.S. flights were canceled. That pace puts 2026 on track for the highest annual cancellation rate in four years. Airlines have not identified one dominant factor, but the combination of weather, construction, and air traffic constraints produced repeated waves of disruption.
Airports With the Highest Cancellation Rates
Airports in the New York region led the list of trouble spots during the summer travel period. LaGuardia recorded the highest cancellation rate, followed closely by Reagan National in Washington. Travelers connecting through these facilities faced elevated risk of missing connections or overnight delays.
| Rank | Airport | Cancellation Rate |
|---|---|---|
| 1 | LaGuardia (LGA) | 6.5% |
| 2 | Reagan National (DCA) | 5.8% |
| 3 | JFK International (JFK) | 4.2% |
| 4 | Boston Logan (BOS) | 3.8% |
| 5 | Newark Liberty (EWR) | 3.7% |
Among the three New York-area airports, Newark posted the lowest cancellation rate this summer. The figures cover U.S. airports with at least 30,000 flights between Memorial Day and Labor Day.
Practical Steps to Reduce Risk
Morning departures continue to offer the strongest chance of on-time performance. Problems tend to build through the day as maintenance issues surface and weather moves in, so an early flight often avoids the cascade of later delays. Frontier Airlines CEO Jimmy Dempsey noted that a clean start in the morning helps the airline stay on schedule for the remainder of the day.
Travelers should also consider credit cards that include trip interruption coverage. Airlines generally do not reimburse meals or hotels for weather-related cancellations, but card benefits can cover those costs when the ticket was purchased with the card. Starting in October, some mechanical delays may receive even less airline support, making such protections more relevant.
Keeping airline and flight-tracking apps updated on a phone allows faster rebooking when problems arise. Downloading entertainment and carrying water and snacks provides a buffer during long ground stops or taxiway waits. Checking the restroom before boarding is also advisable, since seat-belt signs often stay on during extended delays.
Airports With Stronger On-Time Records
Several major hubs posted better results. Salt Lake City led large airports with an 82 percent on-time rate, followed by Minneapolis-St. Paul at 80.1 percent. These facilities serve as key hubs for Delta and United, offering more connection options for passengers who can adjust their routing.
While cancellations increased, overall delay rates remained similar to last summer, with roughly one in four flights affected nationwide. Travelers planning connections may still benefit from routing through airports that demonstrated stronger operational reliability during the busy season.
