A month ago, I saw US$500 round trip flights from Dallas to Shanghai. Now I can't seem to get anything less than $750, no matter what time of the year pick. I am searching Expedia, and Travelocity.
I am going to wander around China to immerse myself in the language, for a month, as a continuation of my Mandarin language studies - so I am not fussy about what time I go. I just want to lower my costs.
Do you have any tips for me? How can I get the cheapest flight to China?
