What do you mean by transit tickets?

Transit ticket is a kind of transit ticket, which means that airlines effectively combine flight resources to form a route network and transport passengers from the departure point to the destination through one or more transit destinations. At the same time, it can give full play to the advantages of convenient and fast air transportation and provide more convenience and benefits for passengers.

Connecting air tickets (connecting flights) is a very important means to buy discounted air tickets. When you buy this kind of air ticket, the routes and flights are generally fixed, and the price is also fixed, so you don't need to make up any more money. Your ticket is from Harbin to Beijing to Sanya, which means taking off in Harbin, connecting in Beijing and arriving in Sanya.

When you transfer, you only need to exchange your boarding pass for the next flight at the transfer counter, without going out of the airport or checking again. At the end of your first trip, the airport will have clear instructions to guide you to transfer.

Extended data:

In recent years, the three major domestic airlines are actively creating convenient transit services. For example, as early as 2006, China International Airlines Co., Ltd. (hereinafter referred to as "Air China") began to plan the whole boarding business around the goal of building a Beijing hub.

From the end of 2006, domestic flights to international flights were launched, and in 2008, a memorandum was signed with the customs of the Capital Airport to start the direct boarding service in Beijing. Subsequently, a memorandum of cooperation was signed with the Customs of Capital Airport and Beijing Capital Airport to launch an international to domestic direct boarding baggage hanging service. Air China is gradually promoting full boarding service.

According to its website, Air China has achieved boarding through Beijing Hub in more than 70 terminals at home and abroad through code sharing, alliance cooperation and network improvement, including more than 40 domestic terminals and 30 foreign terminals.
