Airline regulations vs. airline policy

Airline regulations are government-mandated rules that all airlines must follow by law, while airline policies are individual guidelines each airline creates for its own operations. Regulations always take precedence over policy when the two conflict.

Which body controls airline regulations?

Multiple formal bodies regulate air travel at international and national levels. A variety of formal bodies regulate air travel and the landscape is complex.Major airline regulatory bodies:
  • ICAO (International Civil Aviation Organization) – Global standards – icao.int – Established in 1944 under the Chicago Convention as a UN special agency
  • FAA (Federal Aviation Administration) – United States – faa.gov
  • EASA (European Union Aviation Safety Agency) – Europe – easa.europa.eu
  • CAA (Civil Aviation Authority) – National bodies in individual countries
The ICAO helps its 191 Member States create shared international standards. These standards then provide the basis for national regulations, which are maintained by each country's Civil Aviation Authority.In the US, air travel and air traffic is regulated by the FAA. EASA has the same role in Europe, drafting important safety regulations that determine how airlines should operate.
