Charter is a type of flight that is hired by a GSA (general sales agent) or forwarder to transport goods. In this case, the GSA or forwarder is not representing the carrier, but rather they are buying the entire flight to transport their goods. The GSA or forwarder will then send the tariffs for the charter flight to the shipper or consignee, even though they are not representing the carrier for that flight. Charters are often used for large or specialized shipments that require a dedicated flight, and they can provide an efficient and cost-effective way to transport goods by air.
