ValuePenguin publishes Airport Misery Index has announced results from a recent study that ranked airports according to its misery index, the company said.

Findings from the survey rate Newark Liberty International, John F. Kennedy International and LaGuardia airports were in the top 10 most miserable airports. At Newark´s airport in New Jersey, which took the top spot on the list, more than a quarter of flights are delayed — nearly 12% are delayed over an hour.

More than 4% of flights out of O´Hare International Airport (second on the list) are canceled, while roughly a quarter are delayed.

In colder climates and during the snowy season, flight delays sometimes can´t be avoided due to inclement weather, which is likely why airports in the Northeast and Midwest tend to get slammed during the holidays.

Hartsfield-Jackson Atlanta International Airport (the nation´s busiest) and Sea-Tac Airport in Washington state (the eighth-busiest) both ranked in the bottom half of the misery index. analysts ranked the most miserable airports to fly out of by looking at data for the 84 airports with at least 10,000 departures. Research analysts specifically looked at six variables: flight cancellation rate, flight delay rate, average length of delay, tarmac delay rate, severe delay rate, and security wait time.
