Can travel agencies book hotels and air tickets on their behalf?

Now travel agencies can basically book hotels and air tickets on their behalf. Others, such as online booking, Ctrip and E Long are two leading booking networks, and some hotels have internal booking prices, which will be cheaper than direct door-to-door booking, and can also be considered.

If you don't want to travel with a group all the time, you can book a half-package tour at a travel agency. Let the travel agency only provide transportation, hotel accommodation and scenic spots tickets.
