Can I claim compensation from the travel agency if the tour group's flight is delayed for more than 3 hours after buying aviation insurance?

Hello! Flight delay insurance usually covers the flight delay or flight cancellation of the insured due to force majeure accidents agreed in the contract when passengers travel by air. If the arrival of the insured is delayed or exceeds a certain time due to this situation (your situation is 6 hours), and the airport has not arranged other means of transportation to replace it, the insurance company will make insurance compensation.

According to the insurance liability of your policy, if the flight is delayed or cancelled for more than 6 hours (more than 6 hours), and there are no other flights available for you at the airport, you can apply to the insurance company for compensation for flight delay insurance.
