Contractors cannot work legally without civil liability insurance. A contracting carrier is a carrier that, under a contract of carriage, transports goods from one place to another. Such a freight forwarder does not transfer goods to the general public, but only to a limited number of customers. A contract of carriage is an agreement which, by its nature, is binding and contains the conditions of carriage, including the rights and obligations of a carrier and a consignor. A contract carrier is simply a person or company that transports goods only for a certain number of customers and has the power to refuse to transport goods for other persons. Contractors are different from the usual airlines that most people know. A contract of carriage is a contract between a carrier of goods or passengers and the consignor, consignee or passenger. Contracts of carriage generally define the rights, obligations and commitments of the parties, deal with matters such as the case of force majeure and include clauses such as the case of force majeure. In the case of regular airlines, they are usually subject to standard conditions printed on the back of a ticket or transport document. Notification of the arrival of a shipment is usually sent to the “reporting party” whose address appears on the delivery note. This party is usually either the buyer or the importer.
In July 2010, it became common knowledge that Southwest Airlines had classified mechanical difficulties in its contract of carriage as an act of God and expanded the definition previously shared with Delta, American, Continental, and United.  This issue was then resolved by the airline as mechanical difficulties that are not controlled by the airline, such as. B failure of the air navigation system or fuel distribution systems operated by airports. . . .
