Flying in and around United States
United States is served by 533 commercial airports and approximately 60 airlines registered to the country, generating around 12,986 documented airline-route pairings on file. For budget travellers, the practical question is which of these airports actually have the kind of low-cost service that produces sub-USD-100 fares, and whether the country's largest hub or a secondary regional airport delivers better value door to door.
Use the airport list below to find route counts, served airlines, and direct destinations from each field. Airports are sorted by route volume, so the country's largest hub appears first and useful secondary airports follow. Carrier rules vary widely by airline, so always verify baggage allowances, check-in cutoffs, and booking fees before purchase.
