The 2023 U.S. Airport Rankings rate the 50 busiest airports in the country based on measures of reliability, value and convenience. Each airport is evaluated on 30 factors that span the trip, from buying a ticket to arriving at a final destination. Using data from government agencies, a survey of travelers conducted by our research partner Dynata and other sources, the Journal’s rankings highlight the airports that boast on-time flights, short waits throughout the trip and the amenities that travelers like best. The airports are separated into large and midsize categories based on the number of passengers they accommodate. See the full methodology below.
