TIS Agreements have been created by our team of contract specialists. Each agreement is legally enforceable and have been reviewed by attorneys who specialize in the travel industry. Our agreements are insured for compliance under professional liability coverage through Westchester/Chubb. Chubb has the highest rating an insurance company can receive for claims. What does this mean for you? If a travel advisor has a covered loss as a result of one of our forms, our policy would make them whole.
