Part 135
Why it matters
Why part 135 matters
Charter flights operate under Part 135, which holds them to stricter standards than private, non commercial flying. The certificate holder on your invoice is the operator—not the broker's brand. A quote that will not name the holder is not ready for deposit.
Cost
How it affects cost
Meeting Part 135 standards carries cost in maintenance, training, and oversight, which is built into legitimate charter pricing. A quote far below market may signal corners being cut.

Common questions
What does Part 135 mean for my flight?
It means the flight operates under commercial charter rules with stricter standards for crew, maintenance, and oversight than private, non commercial flying.
How do I know a flight is Part 135?
Ask for the operating certificate holder and certificate number. FAA certificate information is public; the company on your contract should match the certificate holder, not only the broker's marketing name.
Is Part 135 the same as Part 91?
No. Part 91 covers private, non-commercial flying with different rules. Paid charter for third parties operates under Part 135, which carries stricter operational requirements.
