The Bureau of Transportation Statistics has released data showing that 22 percent of all flights in 2018 experienced delays, cancellations or diversions. A figure like that is enough to give a frequent traveler a bit of anxiety. The fact that delays are so prevalent means knowing how to plan a trip that can avoid unnecessary delays is more important than ever. Do you know which airports are the most reliable?

A recent study that took a look at the 20 biggest airports in the country shows that Phoenix Sky Harbor International Airport (PHX) is the most reliable option. PHX earned a score of 72.22 out of 100 based on factors like percentage of on-time flights, percentage of cancelled flights, screening lengths, taxiing times and delay times. Denver International Airport (DEN) came in at second place with a score of 68.47.

Not every major airport scored well. In fact, one of the busiest hubs in the country happens to be the least reliable when it comes to delays. Newark Liberty International (EWR) earned a measly score of 22.7. This year's score is actually an improvement when compared to a score of just 9.7 from the previous year. The Northeast is actually the worst spot in the country for airport reliability. John F. Kennedy International Airport (JFK) and LaGuardia Airport (LGA) joined Newark in the bottom three on this list.
