What airport are most flights cancelled?

  • New Jersey's Newark Liberty International Airport has been named the airport with the highest percentage of canceled flights in the US, according to a new study. ...
  • NYC's LaGuardia and JFK airports joined Newark Liberty International as the US airports that experience the most cancellations.




In 2026, Newark Liberty International (EWR) holds the dubious title of the most "stressful" and frequently cancelled airport in the U.S., with a cancellation rate often hovering around 1.43%. This is largely due to its aging infrastructure being pushed to nearly 300% of its original design capacity and its vulnerability to East Coast weather patterns. On a global scale, Lisbon’s Humberto Delgado Airport (LIS) and London Heathrow (LHR) frequently see high cancellation volumes during peak summer and winter seasons due to staffing shortages and air traffic control constraints. In the winter of 2025–2026, Amsterdam Schiphol (AMS) also saw a spike in cancellations following a significant de-icing and energy crisis. If you are looking for reliability, Singapore Changi (SIN) consistently ranks as the least likely to cancel your flight, with a microscopic cancellation rate of just 0.34% thanks to its world-class efficiency.
