Airfares are a big determining factor of the tour price.CTSI, with strong ties with almost all the airlines that fly between North America and Asia, offers the best price on flight tickets to China and meets various needs of customers.

If you are seeking low-priced tickets to China, you can choose a flight with a layover(停留)，such as Korean Air, Air Canada, and Cathay Pacific.

Chinese Airlines usually offer huge discount on China domestic flights if you purchase both the international and China domestic parts together.

If you wish to save on flying time, we would recommend direct flight provided by America Airlines and United Airlines.
