What Makes a Charter Flight Safe? How Operator Vetting Actually Works

Part 135 is the floor, not the standard. What gets checked on the operator, the aircraft, and the crew before a trip ever carries our name.

Charter safety has a vocabulary problem. Every website in the industry says "safety is our top priority," which tells you nothing, because the words cost nothing. What actually protects you is a stack of verifiable layers — and knowing what they are lets you audit any broker, including us.

First, know who's flying you

JetNine is a broker — a Part 295 indirect air carrier. We don't operate aircraft; we arrange your flight with the carriers that do. Every flight we sell is flown by an operator holding an FAA Part 135 certificate, the commercial charter standard. That split matters: it means our incentive is to choose among operators, not to defend our own fleet. The full picture of the arrangement is in what a private jet broker actually does.

Part 135 is the floor

A Part 135 certificate means the FAA holds the operator to commercial standards: minimum pilot experience and recurrent training, aircraft maintenance programs, crew rest and duty-time limits, drug and alcohol testing, operational control requirements. It is a meaningful bar — far above private (Part 91) flying.

It is also just the floor. Certificates don't distinguish an excellent operator from a merely legal one. That's what the next layers are for.

The third-party audit layer

Independent auditors — ARGUS and Wyvern are the names you'll see — rate operators beyond the regulatory minimum: audited safety histories, verified crew experience against the specific aircraft type, on-site operational reviews at the higher tiers. The ratings have real tiers with real meaning, and we've published a plain-English decoder at safety ratings, explained so a rating on a quote is information rather than decoration.

What we check on top

Certificates and ratings are annual snapshots; trips happen on Tuesdays. Before a specific flight, the vetting gets specific — the operator's current certificate and insurance, this tail's status, this crew's experience in type and in the pairing they're flying. The complete checklist is public: how we vet operators and the pilot standards we require. Publishing it is deliberate — a standard you won't write down is a standard you won't be held to.

Questions you can ask any broker

You don't need to be an aviation lawyer. Four questions separate serious answers from sales copy:

  1. Who is the operator on this trip? Named, not "our network."
  2. What's their third-party rating, and current as of when?
  3. What are the crew's hours in this aircraft type?
  4. What happens if this aircraft goes mechanical the night before? The recovery plan is a safety answer too — the pressure to "just make it work" is where standards die.

A broker who answers all four without flinching is doing the job. Everything we require, in one place: jetnine.com/safety.

— Questions this raises

Asked at the desk

What is the difference between a charter broker and an operator?

The operator holds the FAA Part 135 certificate and flies the aircraft. A broker like JetNine, a Part 295 indirect air carrier, arranges your flight with vetted operators and manages the trip. Our incentive is to choose well among operators, not to defend a fleet of our own.

What do ARGUS and Wyvern ratings mean?

They are independent third-party audits that rate operators beyond the regulatory minimum, covering safety history, crew experience in type, and, at higher tiers, on-site operational reviews. Our ratings-explained page decodes each tier in plain English.

Is Part 135 enough on its own?

It is a meaningful commercial standard and a hard floor, but it does not distinguish an excellent operator from a merely legal one. That is what third-party audits and trip-specific checks on the tail and crew are for.
