The study examined the 30 busiest U.S. airports and used data from the Federal Aviation Administration, the Bureau of Transportation Statistics, J.D. Power, Google Maps, iFly.com and the airports' official websites. Categories included flight delays, cancellations, average security wait times, distance from the city center, public transit options, bars/restaurants, lounges, WiFi costs and parking rates.

The study placed top importance on how well each airport serves its primary purpose – getting you where you're going on time. Next, how easy it is to reach the airport by car or public transportation? The third category is amenities like restaurants and lounges, as well as fees for parking and WiFi.
