Last week the FAA proposed a $351,000 civil penalty against an Arkansas charter operator over 37 passenger flights it says were flown without proper authorization between October 2021 and November 2022. According to the agency, 31 of those flights used aircraft that weren’t listed on the company’s operations specifications, and six more left the contiguous 48 states in aircraft that weren’t approved to go there. The operator disputes the allegations and plans to appeal — but the case is worth your attention for a different reason.
Every one of those 37 flights had passengers on board who almost certainly believed they were on a fully authorized charter. The aircraft were real, the pilots were real, the invoices were real. The authorization wasn’t. That’s the uncomfortable truth about unauthorized charter: from the cabin, it looks exactly like the legal kind.
A Certificate Isn’t the Whole Answer
Most people who book charter know to ask whether the operator holds a Part 135 certificate. That’s necessary, but it’s not sufficient. A certificate comes with operations specifications — the FAA-approved fine print that says which specific aircraft, by serial number, the operator may use for charter, and where it may fly them. An operator can hold a perfectly valid certificate and still fly you unauthorized if the tail number on your trip isn’t on its ops specs, or if your Caribbean routing is outside its approved area.
This isn’t a one-off problem. Between March 2024 and mid-2026, the FAA announced roughly a dozen significant enforcement actions against charter and commuter operators — proposed fines totaling over $1.5 million, plus emergency certificate suspensions and one revocation involving falsified training records on more than 170 flights. Most of these companies weren’t shadowy illegal charters. They were certificated operators flying outside the lines of their own authorizations: unqualified pilots, missed inspections, international charters filed as private flights.
The Red Flags We Watch For
After years of booking trips across a network of more than 500 vetted Part 135 operators, we’ve learned where the problems hide. A few warning signs any charter customer can spot:
- Paperwork that makes you the operator. If a “charter” contract says you’re leasing the aircraft and you’re responsible for the flight — while the company supplies the plane and crew — that’s a classic structure for dodging Part 135 rules, and the liability lands on you.
- No federal excise tax on the invoice. Legitimate domestic charter carries a 7.5% federal excise tax. A quote with no FET line is a question that needs an answer before wheels-up.
- A tail number nobody will confirm. If the broker or operator won’t tell you which aircraft you’re on, you can’t check that it’s on anyone’s ops specs.
- International trips treated casually. Flights beyond the lower 48 need specific authorizations. Six of the 37 flights in last week’s case were exactly this.
How Verification Actually Works
The FAA has made checking easier. Its Safe Air Charter site now includes a searchable list of certificated Part 135 operators, and the agency runs a Safe Charter Operations initiative with a dedicated investigations team and an industry hotline for reporting suspected illegal flights. Before any trip, you — or your broker — should be able to match three things: the operator’s certificate, the specific aircraft on its ops specs, and the authorization for your route.
That’s the vetting we do on every quote, not just the first one. Operators’ fleets change, authorizations lapse, and insurance gets rewritten mid-year. A broker who verified an operator in January hasn’t verified the aircraft you’re boarding in October. And with every Part 135 operator required to have an FAA-accepted safety management system by May 2027, the paper trail separating disciplined operators from the rest is only getting longer.
The lesson from last week’s enforcement action isn’t that charter is risky. It’s that verification is cheap and skipping it is expensive — for the operator facing the fine, and for the passengers who never knew to ask.
