In an effort to help empower passengers to make more informed decisions when booking flights, InsureMyTrip reveals which of the country's busiest airports are more prone to flight cancellations and what passengers should know about airline cancellation policies.

Summary:

Chicago Midway International reported the highest cancellation rates in the country, bad storms and the groundings of 737 Max jets likely contributed to the spike.

Hartsfield-Jackson Atlanta International continues to make an impressive on-time performance comeback in 2019.

New York's LaGuardia no longer reports the highest percentage of canceled flights in the country. The NYC airport now ranks 8th, a significant improvement.

California wildfires led to a significant increase in flight cancellations for Burbank last year.

Salt Lake City International and Kahului Airport maintain a consistent reputation for punctuality, celebrating another year of shocking low cancellations.

This ranking shows U.S. airports with the most and least percentage of flights canceled. This updated list is based on newly released data, which now includes all of 2019.

Airline Cancellation Policies
Flight cancellation policies vary by airline and circumstance. When an airline cancels a flight, most will try to rebook passengers on the next available flight.

Airlines are not required to reimburse travelers for losses incurred as a result of a canceled flight. These losses may include such as a prepaid, non-refundable:

Hotel room
All-inclusive vacation or resort
A cruise
A tour or safari
Concert or entertainment tickets

Travelers concerned about protecting any non-refundable, pre-paid trip expenses should buy travel insurance.
