When you arrive at the airport, you can exchange the original certificate you chose when booking for your boarding pass. If you need reimbursement, you can choose the ticket delivery method at the time of booking. This ticket delivery method will send you a reimbursable travel route.
Enterprises that provide civil aviation services for passengers and goods generally need officially recognized operation certificates or approvals. The aircraft used by airlines can be owned or leased, can provide services independently, and can also form partners or alliances with other airlines. The size of an airline can range from a plane carrying mail or goods to an international airline with hundreds of planes providing various global services. The service scope of airlines can be divided into intercontinental, intercontinental and domestic, and can also be divided into flight service and charter service.
