United States Airport Statistics & Travel Data

Flight cancellation policies vary by airline and circumstance. When an airline cancels a flight due to bad weather, 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, including:

• Hotel fees
• All-inclusive vacation or resort fees
• Cruise payment
• A pre-paid tour or safari
• Concert or entertainment tickets

Travelers concerned about protecting any pre-paid, non-refundable trip expenses should buy a travel insurance policy that features flight insurance benefits.

In an effort to help empower passengers to make more informed decisions while traveling during the 2018 Atlantic hurricane season, InsureMyTrip predicts which US airports are most prone to delays and cancellations and what passengers should know about airline policies.

Airpot Delay Data Summary:

• Researchers ranked the on-time performance for the busiest airports in the Eastern US, the part of the country that is most impacted by tropical storms.*
• Hartsfield-Jackson Atlanta International Airport is ranked the best overall for handling delays and cancellations during hurricane season. It is also the busiest.
• Newark Liberty International, LaGuardia, and John F. Kennedy International are ranked the worst overall for delays and cancellations during hurricane season. All three airports are twice as likely to report a weather delay than any other airport on the list.
• Passengers should anticipate flight disruptions when a storm develops. Nationwide, flight cancellations soared for major US airports in August and September last year due to storms.

Data Methodology

*US airports were ranked by the InsureMyTrip travel data team. Data combined three years of on-time performance statistics for the 25 busiest airports (based on the volume of flight operations) located in Eastern US. On-time performance data included weather delays for airports — including those attributed to extreme weather conditions and delays under the control of the National Airspace System (NAS). The proportion of weather delays to the number of flights was also calculated in addition to the overall number of delays and minutes of delays. Researchers also reviewed the percentage of cancellations (domestic arrivals and departures). Data was obtained by the US Department of Transportation’s (DOT) Bureau of Transportation Statistics (BTS), the agency that tracks the on-time performance of domestic flights operated by large air carriers.

Researchers evaluated on-time data for selected airports during the 2015, 2016, and 2017 hurricane season. The official hurricane season runs from June 1st to November 30th (Source: NOAA).

Peak months for hurricane and tropical storm activity also appears to correlate with a higher number of canceled flights nationwide. For example, the highest percentage of all flights canceled in 2017 were reported during August and September. These months also experienced high storm activity along the Atlantic and Gulf Coast.

InsureMyTrip Research predicts these airports will be more stressful for travelers this holiday due to the likelihood of canceled flights based on previously reported data for this year.

*Data excludes over 1,000 canceled flights due to the power outage of December, 17th 2017 at Hartsfield-Jackson International. Those numbers have not been collected yet.

US Airport Data Summary

• New York's LaGuardia reports the highest percentage of canceled flights in 2017. Winter Storm Stella was a contributing factor, causing the number of grounded flights to soar last March.
• For the first time in five years, Hartsfield-Jackson Atlanta International (ATL) reports more flight cancellations than Chicago O'Hare International (ORD). December's power outage at ATL contributed to the spike. Data analysts predicted this outcome.
• Despite the rise in canceled flights for Atlanta, the airport was average, in terms of percentages — with 1.49 percent of scheduled departures calling it quits.
• Bad weather is the top reason for flight delays and cancellations.
• Overall, flight delays are far more common than canceled flights.
• The list shows the airports with the biggest percentages of flights canceled in 2017.
