Booking a private jet for the first time is not simply a matter of picking an aircraft and confirming a date. Before you sign anything, you will encounter a dense layer of industry-specific language, contract clauses, and operational terms that experienced operators and brokers use fluently, but that most first-time clients in Asia-Pacific have never seen. Understanding this language is not optional; it is the difference between a protected, well-priced flight and a booking full of hidden exposure.
TL;DR
- Private aviation has its own contract and operational vocabulary. Not knowing it puts you at a disadvantage before the ink dries.
- Key contract terms include the Air Charter Agreement, AOC, PIC authority, and indemnity clauses. Each carries real legal and financial weight [skyaccess.com].
- Empty legs are genuine savings opportunities, but only when sourced correctly through a single trusted broker.
- Shopping your charter request across multiple brokers signals false demand to operators and drives prices up, not down.
- L’VOYAGE clients receive expert term-by-term guidance before any contract is signed, backed by decades of in-house industry experience.
About the Author: This glossary is compiled by the team at L’VOYAGE, a government-licensed travel agency and private aviation consultancy established in Hong Kong in 2014. As the first private jet broker in Asia to hold Wyvern Approved Broker status and a named ‘Best Charter Broker’ by AsBAA, L’VOYAGE brings direct, practitioner-level fluency to every term defined below.
What Is an Air Charter Agreement and Why Does Every Word Matter?
An Air Charter Agreement is the binding legal document between a charterer (you, the client) and the operator (the entity that controls and operates the aircraft) that defines the complete terms of your flight [skyaccess.com]. It is not a booking confirmation. It is a contract, and it governs everything from liability to cancellation rights to what happens if the aircraft becomes unavailable.
First-time clients often skim this document. Experienced clients read every clause. The sections that carry the most risk are not always the most prominent ones. Pay particular attention to:
- Force Majeure: Defines which events relieve the operator of performance obligations without financial penalty, including weather, regulatory action, or technical grounds [skyaccess.com].
- Indemnity Clause: Specifies which party bears responsibility for specific losses or liabilities during the flight.
- Cancellation and Refund Policy: States your financial exposure if you cancel at various points before departure. Terms vary significantly between operators [skyaccess.com].
- Substitution Rights: Grants the operator the right to replace the originally agreed aircraft with an alternative. The clause should specify minimum equivalent standards.
A related but distinct concern is who is actually operating the aircraft. This leads directly to one of the most important regulatory terms in the industry.
What Is an AOC and Why Should You Always Ask for It?
An Air Operator Certificate (AOC) is a government-issued authorisation that permits an organisation to operate commercial air transport [privatefly.com][artheauaviation.com]. If the company flying you does not hold a valid AOC for the specific aircraft type and route, the flight is not legally operating as a commercial charter, and your protections under aviation law are fundamentally different.
Key terms connected to AOC status:
- Wet Lease: The operator provides the aircraft, crew, maintenance, and insurance (ACMI). The charterer pays for the complete service. This is the standard arrangement in private charter [privatefly.com][flycraft.com].
- Dry Lease: The operator provides the aircraft only, with the lessee responsible for crew and operations. Not typical in client-facing charter arrangements [flycraft.com].
- PIC (Pilot-in-Command): The captain holds final authority over the safety of the flight, regardless of any client instruction. This is non-negotiable under all major aviation regulations [privatefly.com][stratosjets.com].
Always request the operator’s AOC documentation before signing. A reputable broker will provide this without being asked.
What Are Positioning Fees and Empty Legs?
Building on the contract terms above, the harder question for cost-conscious clients is how charter pricing is actually constructed and where legitimate savings exist.
Positioning fee (also called a deadhead or ferry fee): When the aircraft needs to fly empty to reach your departure point, the cost of that repositioning leg is typically passed to the charterer, either as a line item or embedded in the quoted price [privatefly.com][stratosjets.com]. Understanding this explains why identical routes can carry very different price tags depending on where the aircraft is based.
Empty leg: The inverse situation. When an operator has already committed to a repositioning flight, they will often sell that sector at a significant discount to recover some cost [privatefly.com][artheauaviation.com]. Empty legs are real and represent genuine value for flexible travellers.
However, there is a critical caveat that most first-time clients miss entirely. When the same charter request is submitted to multiple brokers simultaneously, operators receive duplicate inbound queries for the same trip. This signals artificially high demand, and operators price accordingly. The “deal” you were hunting becomes more expensive the more brokers you engaged to find it. This dynamic applies to both standard charters and empty legs.
L’VOYAGE clients work with one trusted broker rather than distributing the request across the market. This keeps the operator signal honest and protects the client’s pricing position. The advantage is consultative, not transactional.
What Other Contract and Operational Terms Should You Know?
The following terms appear frequently in charter agreements and pre-flight briefings. Knowing them before you sit across from a broker or operator removes the information asymmetry that can cost you money or leave you underprotected [flycraft.com][skyaccess.com][stratosjets.com].
| Term | Plain-Language Definition |
|---|---|
| Block Hours | Pre-purchased flight hours, typically sold by operators as a membership product. Guarantees access but not always best market pricing [flycraft.com]. |
| FBO (Fixed-Base Operator) | The private terminal and ground services facility used for private aviation, separate from commercial terminals [privatefly.com][stratosjets.com]. |
| Overflight Permit | Government authorisation required for an aircraft to pass through a country’s airspace without landing [stratosjets.com]. |
| Slot Time | A specific window allocated for departure or landing at a controlled airport. Missing a slot can result in significant delays [privatefly.com]. |
| MTOW (Maximum Take-Off Weight) | The certified maximum weight at which an aircraft is permitted to take off. Relevant to payload, range, and certain regulatory requirements [stratosjets.com]. |
| Trip Support | Ground-level operational services including permits, handling, catering coordination, and crew logistics, often managed by the broker [flycraft.com]. |
| Cabotage | The legal restriction preventing a foreign-registered aircraft from operating domestic routes within another country [stratosjets.com]. Relevant for multi-leg itineraries in Asia-Pacific. |
Frequently Asked Questions
What is the difference between a charter broker and an operator?
An operator holds the AOC and physically controls the aircraft. A broker sources and arranges the flight on your behalf but does not operate the aircraft. The broker’s value lies in network access, safety vetting, and negotiation expertise [artheauaviation.com].
Is an empty leg always a good deal?
An empty leg is a good deal when it genuinely aligns with your route and timing, and when it is sourced through a single broker with a vetted operator network. Empty legs shopped across multiple brokers lose their pricing advantage as operators register inflated demand signals.
Why do charter prices vary so much for the same route?
Positioning requirements, aircraft base location, demand levels, and how many brokers are simultaneously quoting the same trip all influence the final price [privatefly.com][skyaccess.com].
What does it mean when a broker says a flight is “subject to availability”?
The aircraft has not been formally held or confirmed. The quote is indicative, not guaranteed, until a charter agreement is signed and a deposit is made [skyaccess.com].
What is Wyvern Approved Broker status?
Wyvern is an aviation safety and standards organisation. Wyvern Approved Broker status indicates the broker has met defined criteria for safety vetting, operator due diligence, and compliance practices. L’VOYAGE was the first private jet broker in Asia to hold this designation.
