Denver International Airport ranked eighth-worst among busiest U.S. airports

DENVER -- A study compared the 30 busiest airports in the country and found Denver International Airport was in the bottom 10.

ThePointsGuy.com looked at flight delays, cancellations, average security wait times, distance from the city center, public transit options, bars/restaurants, lounges, Wi-Fi costs and parking rates.

DIA was ranked the eighth worst overall.

"DIA ranked in the bottom five for accessibility, average security wait time and lounge availability," according to the study.

DIA's score was boosted by the availability of free Wi-Fi and relatively cheap parking. DIA has the sixth-cheapest parking out of the 30 airports in the study.

This study had different results than a separate worldwide customer survey earlier this year. The Skytrax World Airport Awards ranked DIA among the best airports in the world. The airport was in the top 10 in several Skytrax categories.

ThePointsGuy study found Phoenix Sky Harbor International Airport is the best U.S. airport and New York’s LaGuardia Airport is the worst.

"[Phoenix Sky Harbor] has the shortest driving time from the city center, the second-shortest public transit time, the third-cheapest parking, the third-most bars/restaurants per capita and the fifth-fewest flight cancellations," researchers said.

"LaGuardia has the most flight delays and cancellations and the most expensive parking among the 30 surveyed airports," according to researchers.
