List of airports in California

This is a list of airports in California (a U.S. state), grouped by type and sorted by location. It contains all public-use and military airports in the state. Some private-use and former airports may be included where notable, such as airports that were previously public-use, those with commercial enplanements recorded by the FAA or airports assigned an IATA airport code.

Airports

This list contains the following information:

• City served - The city generally associated with the airport. This is not always the actual location since some airports are located in smaller towns outside of the city they serve.
• FAA - The location identifier assigned by the Federal Aviation Administration (FAA). These are linked to each airport's FAA Master Record (Form 5010) from AirportIQ 5010 (website of FAA contractor that maintains the database).
• IATA - The airport code assigned by the International Air Transport Association (IATA). Those that do not match the FAA code are shown in bold.
• ICAO - The location indicator assigned by the International Civil Aviation Organization (ICAO).
• Airport name - The official airport name. Those shown in bold indicate the airport has scheduled service on commercial airlines.
• Role - One of four FAA airport categories, as per the 2009-2013 National Plan of Integrated Airport Systems (NPIAS) Report:
  • P: Commercial Service - Primary are publicly owned airports that receive scheduled passenger service and have more than 10,000 passenger boardings (enplanements) each year. Each primary airport is sub-classified by the FAA as one of the following four "hub" types:
    • L: Large Hub that accounts for at least 1% of total U.S. passenger enplanements.
    • M: Medium Hub that accounts for between 0.25% and 1% of total U.S. passenger enplanements.
    • S: Small Hub that accounts for between 0.05% and 0.25% of total U.S. passenger enplanements.
    • N: Non-Hub that accounts for less than 0.05% of total U.S. passenger enplanements, but more than 10,000 annual enplanements.
  • CS: Commercial Service - Non-Primary are publicly owned airports that receive scheduled passenger service and have at least 2,500 passenger boardings each year.
  • R: Reliever airports are designated by the FAA to relieve congestion at a large commercial service airport and to provide more general aviation access to the overall community.
  • GA: General Aviation airports are the largest single group of airports in the U.S. airport system.
• Enpl. - The number of enplanements (commercial passenger boardings) that occurred at the airport in calendar year 2008, as per FAA records.
