Key Tips
ATL, ORD, DFW, DEN, and LAX are the five busiest airports in the US — allow extra time for connections at these airports.
Many US cities are served by multiple airports — compare prices and convenience for all options.
Secondary airports (BUR, LGB, MDW, OAK) are often less congested and can offer cheaper fares than primary airports.
