Most of a charter agreement is standard wording. The terms below are the ones worth reading slowly, because they decide what happens when something changes. Read them before you send a deposit, and ask your broker to explain anything that is not clear. A good broker will be glad you asked.
The eleven terms at a glance
| Term | What good looks like |
|---|---|
| 1. Operator | The operator in operational control is named, with its certificate, before you pay. |
| 2. Aircraft and substitution | Type named; substitutes of the same or a larger category; your right to decline. |
| 3. Price | An all-in figure listing taxes and known fees. |
| 4. Variable charges | De-icing, catering, Wi-Fi and extra waiting explained in advance. |
| 5. Payment | Clear dates for deposit and balance, paid to a named company. |
| 6. Cancellation | A dated scale of charges you can plan around. |
| 7. Schedule changes | How changes to times and routing are requested and priced. |
| 8. Delays | What happens after a weather or maintenance delay, and who decides. |
| 9. Passengers and bags | Limits for weight, size, numbers and pets stated up front. |
| 10. International documents | Who submits passenger data to customs, and by when. |
| 11. Liability and law | The contracting entity and governing law are clear. |
What each term means in practice
1. The operator in operational control
The agreement should name the direct air carrier that will operate the flight and hold operational control. If it names only the broker, ask for the operator before you pay. This is the single most important line in the document.
2. Aircraft type and substitution
Look for the aircraft type and, ideally, the tail number. Then read the substitution clause. If the aircraft becomes unavailable, what replaces it? A fair clause offers an aircraft of the same or a larger category at no extra cost and lets you decline a smaller one.
3. Price and what it includes
An all-in price should list the 7.5% federal excise tax on domestic flights, segment fees, and the landing, handling, repositioning and crew costs known at the time of booking. If any figure is described as an estimate, ask what could change it.
4. Variable charges
Some costs depend on the day itself. Winter de-icing is the best-known example; special catering, Wi-Fi usage, extra waiting time and unplanned crew overnights are others. The agreement should say how each is charged, so nothing arrives as a surprise on the final invoice.
5. Payment schedule
Check when the deposit and balance are due, which payment methods are accepted, and the name on the receiving account. Payment should go to the operator or to the broker named in the agreement, never to an individual.
6. Cancellation
Most agreements use a dated scale: the closer to departure you cancel, the more you pay. Read the exact cut-off times and the time zone they refer to. If your plans are uncertain, ask about the scale before you sign rather than after.
7. Changes to the schedule
Moving a departure by a few hours can be simple, or it can change the price, depending on crew duty limits and where the aircraft has to come from. The agreement should explain how changes are requested and how they are priced.
8. Weather, maintenance and other delays
The operator decides whether a flight can go safely, and the agreement should say so. Look for what happens next: a later departure, an alternate airport, a replacement aircraft, or a credit or refund. Mountain airports in winter and coastal airports in fog are typical places where this clause matters.
9. Passengers, bags and pets
Aircraft have firm weight and space limits, and the agreement may state the maximum number of passengers and bags. Declare skis, golf clubs, large cases and pets in advance. Pets travel at the operator's discretion and may need a carrier or a seat cover.
10. International travel documents
For flights abroad, check who submits passenger information to customs and border authorities, and by when. Passports, visas and pet entry papers remain each traveller's responsibility, so confirm them early.
11. Liability and governing law
This clause sets out whom you can claim against and under which law. It is usually standard, but it is worth knowing which company you are contracting with and where a dispute would be heard.
A note on deposits
A deposit secures the aircraft and crew for your dates, and operators often turn away other bookings once it is paid. That is why the cancellation scale usually starts as soon as the agreement is signed. Before you pay, check three things: that the agreement is signed by the company you are paying, that the deposit amount matches the payment schedule, and that you have the full agreement, not only an invoice. Keep the confirmation with your trip documents, and ask your advisor for a written summary of the cancellation dates so you do not have to search the contract later.
Before you send the deposit
Ask for the agreement in writing, read it with your own trip in mind, and confirm anything that matters to you by email. If a clause seems unusual, ask why it is there. The answer is often simple, and when it is not, you will want to know before money moves. For the operator checks that sit behind the contract, see how to check a charter operator.
