Every charter website in the country displays the same row of logos near the footer. Gold shields, blue wings, a certification seal or two. Private jet safety ratings are the industry's shorthand for "we checked," and they do real work, but the badge on a broker's homepage tells you almost nothing on its own. What matters is which rating applies to the specific tail number flying your trip, and whether the broker treats that rating as a floor or as decoration.
We run this check on every mission before we quote it, so here is the plain version of what each rating audits, what it does not, and the one question that separates a policy from a logo.
The regulatory floor comes first, and it is not a rating
Before any third-party badge enters the picture, there is federal law. Commercial charter in the United States is flown under FAA Part 135, which governs crew training, duty and rest limits, maintenance programs, and operational control. A broker like us operates under Part 295 as an indirect air carrier, which means we arrange the flight and a Part 135 certificate holder actually operates it.
That distinction is the foundation everything else sits on. Part 135 is mandatory and binary: an operator either holds the certificate or cannot legally sell you a seat. The ratings discussed below are voluntary audits layered on top. They exist precisely because the regulatory minimum is a minimum, and the gap between "legal" and "how we would want our own family flown" is wide enough that a whole audit industry grew inside it.
If you want the long form on how the pieces fit together, our safety standards page lays out the written floor, and how charter operator vetting actually works walks through the process end to end.
ARG/US Gold and Platinum audit the operator
ARG/US (Aviation Research Group/US) is the most widely cited independent auditor in North American charter. Its ratings come in tiers, and the two you will encounter are Gold and Platinum.
Gold is a historical safety analysis. ARG/US pulls the operator's certificates, insurance coverage, pilot records, and aircraft maintenance history and verifies them against its own databases and the FAA's. Passing means a third party confirmed the paperwork is real, current, and clean. That sounds modest until you consider the alternative, which is taking an operator's word for it.
Platinum adds the part that cannot be done from a desk. Auditors go on site and observe the operation in practice: emergency response planning, ground handling procedures, security protocols, and whether the safety management system is a functioning process or a binder on a shelf. An operator can assemble clean records and still run a sloppy ramp. Platinum is the tier that catches the difference.
We hold ARG/US Gold as a hard floor across our network, and Platinum operators take priority when two airframes price alike. The full tier-by-tier breakdown lives on our ratings explained page.
Wyvern Wingman audits the trip, not just the company
Here is the distinction most readers miss, and it is the single most useful thing to understand about private jet safety ratings.
ARG/US answers the question "is this operator safe?" Wyvern answers a narrower and more immediate one: "is this crew, on this specific airframe, on this route, today, within acceptable risk?"
Wyvern Wingman operators run a documented risk assessment per leg. The system looks at the assigned captain and first officer, their individual experience and currency in that aircraft type, the specific tail number's records, and the conditions of the flight itself. A crew that is perfectly qualified for a daytime departure out of a long dry runway may not clear the same threshold for a night approach into a short mountain strip in weather.
That per-leg granularity is why we require Wingman or its equivalent for international, transoceanic, and ultra-long-range missions, where the variables multiply and the diversion options thin out. On a clear-weather hop between two major metros with a familiar operator, the operator-level rating carries most of the weight. On a winter approach into terrain, the trip-level check is the one doing the work.
IS-BAO Stage 2 certifies the safety culture
IS-BAO is the International Standard for Business Aircraft Operations, published by the International Business Aviation Council. It is structured in stages, and Stage 2 is the one worth knowing.
Stage 1 confirms a safety management system exists and is documented. Stage 2 confirms it is actually running: implemented, audited, and demonstrably shaping day-to-day decisions. The gap between those two stages is the gap between an operator that wrote a hazard reporting policy and an operator whose line pilots actually file hazard reports and see something change as a result.
IS-BAO carries particular weight with large-cabin and international operators, partly because it is built on ICAO standards and is recognized well outside the United States. We accept Stage 2 alongside Wyvern Wingman as a qualifying standard for long-haul and international flying.
The question that separates a floor from a logo
Everything above is available on any auditor's website. The part that is not published is how your broker uses it, and that is where the real variance lives.
Ask any broker this, in these words: is the rating a floor or a decoration? Meaning, does every operator in your network hold it, with no mission flying without it, or do some of your operators happen to hold it while others do not? Both answers can be delivered while the same logos sit on the same homepage. Only one of them is a policy.
The follow-up worth asking: what happens when an operator's audit lapses? Ratings expire. An audit that was current in March may not be current in September, and an operator drifting out of compliance rarely announces it. The correct answer is that the operator stops receiving trips until the audit is renewed, and that standing is re-verified against the live auditor databases at booking time rather than at some annual review. We check ours at quote time, which is why the reasons charter quotes differ between brokers often come down to which operators a desk is willing to put on the trip at all.
What this means when you are actually booking
Practically speaking, you should not have to memorize any of this. The requirement ought to attach itself to the mission profile automatically, without you knowing to ask.
A domestic light or midsize trip flies on the Gold floor, usually with a Platinum operator. Anything crossing an ocean or pushing into ultra-long-range territory picks up the Wingman or IS-BAO Stage 2 requirement on top. You describe where you are going and when, and the qualifying standard is a consequence of that, not a separate decision you make under time pressure the night before departure.
What you can reasonably do is spot-check. Ask which operator is flying your trip and what it holds. A desk that can answer in one message, with a tail number and a current audit standing, is a desk that ran the check. A desk that has to go find out is telling you something useful too.
For the broader picture on how we screen operators before they ever reach a quote, see operator vetting. If you are earlier in the process and just want a realistic range for the mission you have in mind, the cost calculator is the faster place to start.
Questions this raises
Asked at the desk
Gold is a records-based audit: certificates, insurance, pilot files and maintenance history verified by a third party. Platinum adds an on-site audit of the operation itself, including emergency response planning, ground handling and a safety management system observed in practice.
They answer different questions rather than ranking against each other. ARG/US rates the operator, while Wyvern Wingman runs a documented risk assessment for each individual leg covering the assigned crew, the specific aircraft and the conditions of that flight.
No. FAA Part 135 is the mandatory regulatory floor for commercial charter, and every legal operator holds it. Third party ratings such as ARG/US, Wyvern and IS-BAO are voluntary audits layered on top of that minimum.
At JetNine the operator stops receiving missions until the audit is current again. Audit standing is re-verified against the live auditor databases at booking time, not only at an annual review.
Domestic light and midsize trips are well served by the ARG/US Gold floor, and most fly on Platinum operators. International, transoceanic and ultra-long-range missions should add Wyvern Wingman or IS-BAO Stage 2 on top.
