ARGUS

ARGUS International audits charter operators and publishes safety ratings (for example Gold and Platinum tiers) used by corporations and brokers to vet Part 135 operations.

Why it matters

Why argus matters

An ARGUS rating is a widely used signal of an operator's safety standards, helping travelers and brokers gauge an operation without inspecting it directly. A red flag is a broker citing ARGUS without naming which operator on your trip holds the rating.

Cost

How it affects cost

Highly rated operators may not be the cheapest, but the rating reflects a verified safety standard. Choosing on price alone risks compromises that a strong rating helps you avoid.

Example

A quick example

A broker proposes two operators for the same trip. One holds a strong ARGUS rating and quotes slightly higher, which many buyers accept as worthwhile for the verified safety standard.

Common questions

What does an ARGUS rating mean?

It reflects an independent audit of an operator's safety, including its history, training, maintenance, and procedures. A strong rating signals a higher, verified standard.

Should I only fly ARGUS rated operators?

A strong rating is a helpful signal, but it is one of several. Confirm certification, ask about crew experience, and use a reputable broker to vet operators.

Where do ARGUS ratings come from?

ARGUS International conducts audits of operator safety systems and assigns rating tiers. Ask which operator on your trip holds the rating, not just whether the broker mentions ARGUS.
