How to check a charter operator is legal

What “illegal charter” means, and why it matters to you

In the U.S., an air charter, which the FAA also describes as commuter or on-demand operations, is flown under 14 CFR Part 135. The FAA says this requires a higher level of pilot training and certification, maintenance procedures and safety rules than a private pilot taking friends for a ride, and that its inspectors check charter pilots, crew and aircraft more often than private operations.

Illegal charter is passenger flying for compensation without that authority, or outside its limits. NBAA and the Air Charter Safety Foundation both describe two forms: operators that are not certificated by the FAA at all, and certificated Part 135 operators flying outside the scope of their certificate, for example in an aircraft or an area they are not authorized for. NBAA also lists brokers that present themselves as the actual air carrier.

What it can mean for passengers

• Less oversight. According to the FAA, illegal operators avoid formal oversight by FAA inspectors, higher maintenance standards, more stringent crew training and testing, crew duty and rest rules, and FAA-approved drug and alcohol testing.
• Insurance that may not respond. The FAA lists “adequate insurance for flight participants” among the things illegal operators avoid. NBAA notes that a noncommercial operator typically does not carry the same insurance as a commercial one, and an insurer may not cover a claim if it believes the flight was really for hire. The Air Charter Safety Foundation goes further: if an accident occurs, any insurance such a company carries “is likely to be invalid.” NATA’s consumer sheet warns that passengers may then find their own assets at risk.
• Tax and customs exposure. NBAA says that if the IRS decides a flight was commercial, there can be federal excise tax liability, and commercial flights also carry Customs and Border Protection fees. NATA says the uncollected tax can leave passengers open to IRS scrutiny, back taxes and penalties.
• Unclear responsibility. One of the FAA’s red-flag questions for passengers is simply: “Am I liable for the flight (do I have operational control)?”

A $351,000 proposed fine, and what it shows

On October 19, 2026, the FAA announced a proposed $351,000 civil penalty against an Arkansas charter company for allegedly conducting unauthorized passenger-carrying flights. As reported by AvWeb and stated in the FAA’s announcement, the agency alleges:

• 31 passenger-carrying flights between October 2021 and July 2022 using three aircraft that were not on the company’s Operations Specifications;
• 6 passenger-carrying flights between April and November 2022 on two aircraft that were on its Operations Specifications, but outside the 48 contiguous United States, where it was not authorized to fly them;
• that all 37 alleged violations were conducted “knowingly, carelessly, and recklessly.”

These are the FAA’s allegations and the penalty is a proposal. In a statement reported by Aviation International News, the company said it disagrees with the allegations and intends to address them through the appropriate process. AvWeb notes that the FAA did not identify the aircraft or the destinations involved.

Six checks before you fly

1. Ask who will actually operate the flight, and get it in writing

   Many trips are sold by a broker but flown by a separate operator. Under U.S. Department of Transportation rules for air charter brokers (14 CFR Part 295), before you contract, a broker must tell you the corporate name of the air carrier in operational control of the aircraft, plus any other names that carrier uses publicly, and the capacity in which the broker is acting. Broker advertising must also state that it is a broker, not the air carrier. Ask for the operator’s legal name in writing, and for its air carrier certificate or at least its certificate number, as NBAA suggests.

2. Look the operator up with the FAA

   The FAA publishes a Part 135 Operators and Aircraft List (linked from its Safe Air Charter page). It is a spreadsheet, updated weekly, that the FAA says you can use to verify whether an operator is certificated for charter and which aircraft are authorized, searching by operator name or N-number. It lists each certificate holder’s name alongside the authorized aircraft’s make and model, registration (N-number) and serial number.

   The FAA also offers the AVInfo Air Operator Search, which lets you search by an operator’s legal or “doing business as” name. Choose Part 135, and check “Show Aircraft” to see make, model and series. The FAA says it is working on merging the two tools. If you cannot find an operator or aircraft, the FAA’s advice is to contact your local Flight Standards District Office (FSDO) to verify its charter status.

3. Match the aircraft to the certificate

   Ask for the tail number of the aircraft that will fly your trip, then confirm it appears under that same operator on the FAA list. An FAA inspector suggests asking for a copy of the operator’s operations specification D085, which together with its certificate shows that the aircraft is authorized. You can also look up an N-number in the FAA Aircraft Inquiry registry, which the FAA points charter customers to. For trips abroad, ask whether the operator is authorized to fly to your destination: NBAA notes that flights outside an operator’s authorized areas can be illegal charter.

4. Ask for proof of insurance

   NATA’s consumer guidance is to ask the operator for its insurance certificate as well as its Part 135 certificate, and to be wary if it is less than forthcoming. If you book through a broker, Part 295 also requires the broker to tell you, before you contract, whether it holds liability insurance covering you, your passengers and property on the flight, and its limits.

5. Read the contract and the invoice

   The FAA says legitimate operators have to charge federal excise tax, so it should appear on your bill. NBAA flags separate bills for one flight, such as one for the aircraft and another for the pilots, and NATA advises being highly suspicious of any arrangement that has you pay the pilots or aircraft owner directly. NATA also suggests consulting legal counsel on complex or questionable agreements.

6. Consider independent safety audits, as an extra layer

   Some operators also hold ratings or registrations from private audit programs. They use different criteria and are no substitute for the FAA authority above. We describe them here as their organizations do and do not endorse any of them:

   • ARGUS says its Gold rating requires, among other checks, that an operator has held its certificate for at least a year, crews all flights with two qualified pilots and passes a search of NTSB and FAA records; its Platinum rating adds a two-day onsite audit, renewed every two years.
   • WYVERN offers Wingman certification and says its Wingman Standard is based on ICAO standards for commercial air transport, the Safety Management International Collaboration Group’s standards for safety management systems, and common industry best practice. Its PASS reports compare operator, aircraft and pilot information against a predefined standard.
   • IS-BAO is the International Business Aviation Council’s voluntary safety standard, launched in 2002. IBAC says its audits focus on the maturity of an operator’s safety management system, in three stages.

   If a rating matters to you, ask for the current one for the specific operator flying your trip, and confirm it with the program itself. Our questions to ask jet card providers include a question on safety audits that you can reuse for any charter.

Red flags of illegal charter

Drawn from FAA, NBAA and NATA guidance. One sign alone does not prove a flight is illegal, but each is worth a direct question.

• Reluctance to show the certificate. The operator will not provide its air carrier certificate or certificate number, or the authorization for the aircraft. The FAA suggests finding an operator that will (FAA, NBAA).
• You are handed operational control. The company provides the aircraft and at least one crew member, yet any document tries to transfer operational control to you (FAA).
• No federal excise tax, or a price that seems too good to be true (FAA, NBAA).
• Split bills or direct payments. Separate bills for the aircraft and the pilots, or being asked to pay the pilots or owner directly (NBAA, NATA).
• No safety briefing or passenger briefing cards (FAA).
• Evasive answers to questions or concerns. The FAA says legitimate operators should be transparent and helpful.
• Coaching on what to tell the FAA. The pilot or anyone connected with the company tells you what to say if an FAA inspector meets the aircraft (FAA, NBAA).
• A broker that looks like the airline. NBAA lists a broker appearing to be the actual air carrier as a form of illegal charter. DOT rules require brokers to say they are not the air carrier.
