For every passenger, whether to buy aviation insurance is completely voluntary, and passengers can get a refund before the insurance takes effect. Enterprises or individuals engaged in air transport or other aviation business pay a certain amount of insurance premiums to insurance companies so that they can get economic compensation when they suffer losses due to flight accidents during the insurance period. The insurance in the air ticket is paid by the insurance company to the airline, and then paid by the airline to the passengers. Aviation insurance means that passengers claim directly from the insurance company with the insurance policy.
