The air operator certificate is the licence that allows a company to fly passengers for hire. This guide explains what an AOC is, who issues it, and why it is the first thing to confirm before you charter.
An air operator certificate, often shortened to AOC, is the approval a civil aviation authority grants a company to conduct commercial air transport. It confirms the operator meets the required standards for organisation, maintenance, crew training, and safety management.
In the United States the equivalent approval for on demand charter is issued under FAA Part 135. In Europe operators hold an EASA air operator certificate. Other countries have their own authorities and equivalent certificates.
An AOC is specific. It lists the aircraft types the operator is approved to fly, the kinds of operation permitted, and the areas in which it may work. An operator cannot simply fly any aircraft on any route under one blanket approval.
This is why it matters to confirm that the certificate covers your particular aircraft and flight. The right question is not only whether an operator holds an AOC, but whether it holds the right one for your trip.
Holding an AOC means the operator is subject to ongoing oversight, including audits, maintenance checks, and crew training requirements. The authority can suspend or revoke the certificate if standards slip.
This continuous supervision is the core difference between a certificated commercial operator and a private flight. When you charter, you want the protections that come with that oversight.
Ask who will operate your flight and request the operator name and certificate details. If you are booking through a broker, the broker arranges the flight but does not operate the aircraft, so the operator behind the flight is the party whose AOC counts.
A reputable operator or broker will confirm these details in writing. Pair the certificate check with independent safety ratings and insurance for a complete picture.
