回复：请推荐买回国机票的网站或旅行社，谢谢。

I try to use flychina.com this week. It does not as cheap as it appear to be. It shows you one price, then when you click "Book" button, it says this low fair is sold out, it addes 15% on top of it, that is the price you need to pay.

But seems like this web site does provide you a "bottom line" price for the route you choose to go. I get the price listed on flychina.com from another travel agent.

I have lived in Northeast, Northwest, and Southeast of USA. Seems like most of the time the travel agent that is closest to where you live provides the best price. Different travel agency has different deals with the airlines as one of the agent explain to me, which make sense.
