List of cities with more than one airport

Many cities contain more than one airport, typically to avoid congestion, and where there may be factors preventing expansion to existing airports. In other cities, multiple airports may be built to cater for specific uses, such as between international and domestic flights. The following lists cities which are served by more than one airport offering scheduled passenger services. Military airbases (without passenger service) and airports serving only charted flights are not included.

The main disadvantage of multiple airports is that there is almost never a good way to connect between two airports as part of a connection between flights. For this reason, places such as Atlanta that handle many connecting traffic flows do not have a second airport, nor do they need one.
