5,000 operators go in. 380 come out.

Five stages, every operator.

The network’s published funnel, re-run every twelve months.

1. 01
   ~5,000

   The starting universe

   Every certificated Part 135 charter operator in the United States. Anyone can broker flights across this whole list — most brokers effectively do. The vetting below is what separates a network from a directory.

2. 02
   ~2,100

   Certification & insurance filter

   We drop operators with certificate amendments under review, enforcement actions in the last 24 months, insurance below our $300M–$500M hull-and-liability floor, or fewer than five years of continuous Part 135 operation. Financial standing is verified — no bankruptcy, receivership, or repossession events in the last 36 months.

3. 03
   ~880

   Audit-standing filter

   Below ARG/US Gold, or with a lapsed audit, an operator is out — no exceptions. Any NTSB-reportable event in the last 24 months is disqualifying. For international, transoceanic, and ultra-long-range missions, we additionally require Wyvern Wingman or IS-BAO Stage 2.

4. 04
   ~410

   On-site visit & chief-pilot review

   Our chief pilot — or a qualified third party applying JetNine standards — walks the maintenance hangar, training facility, and dispatch operation in person. Roughly half the operators that look good on paper don't survive a site visit. That number is why this stage exists.

5. 05
   380

   In the network

   Operators currently flying for our clients. Approval isn't permanent: documents are re-reviewed and sites re-visited every twelve months, trip-level checks run before every booking, and random spot-checks plus a crew tip line run continuously. One strike on safety — out.

The written floor behind these filters — certification, audit standing, pilot qualification, insurance, maintenance, safety record, operator stability — is published in full on the safety standards page. What the certifications themselves mean is on ratings, explained.
