No. Charter brokers may sell a charter without disclosing a broker. However, under FAR Part 295, you are entitled to a full refund at the time they communicate who the operator is. After operator disclosure, the DOT notes, “[A]ir charter brokers must provide the charterer with the opportunity to cancel the contract for charter air transportation, including any services in connection with such contract, and receive a full refund of any monies paid for the charter air transportation and services.”
