THE SHORT ANSWER
Aircraft size alone is not enough to answer whether a flight is safe, and a general airline statistic should not automatically be applied to an unfamiliar charter. For a US charter, first identify the operation, then check the operator’s certificate and the aircraft’s charter authorization through the FAA. That is a useful authorization check—not a safety score or a prediction for your flight. [1] [3] [4]
1. Identify the operation, not just the plane
The National Transportation Safety Board’s statistical glossary separates Part 121 air carrier operations, Part 135 commuter and on-demand operations, and general aviation. General aviation primarily includes noncommercial Part 91 operations. These are categories for understanding the evidence, not a ranking from safest to least safe. [1]
A published schedule is not enough to classify a flight. The FAA says Part 135 authority can cover on-demand operations, including limited scheduled services, or scheduled commuter operations that also permit on-demand services. Each has specific limitations. Ask which kind of operation you are booking rather than deciding from aircraft size or the timetable. [2] [1]
The numbers 91, 121 and 135 identify regulatory categories here; they are not risk figures. This guide supplies no accident-rate comparison, boarding fatality rate or personal odds. Its purpose is to help you identify the relevant operation and complete a bounded authorization check.
2. Ask for the certificate before booking
The FAA’s passenger guidance says to verify a charter operator’s legitimacy before booking. When paying for an air charter, ask to see the operator’s Air Carrier or Operating Certificate to validate authorization for charter use. [3]
A practical message is: “Who will operate this flight? Please show me that operator’s Air Carrier or Operating Certificate and provide the proposed aircraft’s registration number, or N-number, so I can check FAA charter authorization.” This gives you the operator and aircraft identifiers needed for the next step. [3] [4]
3. Check both the operator and the aircraft
Open the FAA’s FAA-certificated Aircraft Operators page. Its Part 135 Operators and Aircraft List is intended to verify whether an operator is certificated for charter and which aircraft are authorized. Search using the operator name or aircraft N-number. The FAA says the resource is updated weekly. [4]
Check the proposed aircraft as well as the operator. Finding a company name is not the whole task: the FAA resource also identifies which aircraft are authorized for charter. [4]
For an operator-name search, the same FAA page also points to AVInfo Air Operator Search. It accepts the operator’s name or doing-business-as name, often shortened to DBA, to verify charter authorization and find additional operator information. [4]
4. Follow the FAA’s two fallback rules
If the operator or aircraft is missing from the list, contact your local Flight Standards District Office, or FSDO, to verify charter status. A missing search result is a reason for FAA follow-up—not, by itself, a definitive finding that the flight is illegal or unsafe. [4]
If the operator refuses to show the required authorization, the FAA advises looking for a charter operator willing to provide it. You do not need to turn that refusal into your own safety calculation; follow the passenger guidance and seek another operator. [3]
5. Know what the check settles—and stop there
This guide covers US charter authorization checks, not foreign-charter procedures or a universal legal test for private or sightseeing flights. The NTSB statistical categories discussed here concern US-registered civil aircraft and exclude military operations; they do not establish worldwide personal risk. [1] [3]
Your immediate next step is to request the certificate, operator name and proposed aircraft N-number. Once you have checked operator-and-aircraft authorization through the FAA resources—or obtained FSDO clarification—you have completed this guide’s pre-booking task. That establishes authorization information, not an audit of the operator or a promise about your flight’s outcome. [3] [4]
