I was traveling last Wednesday (July 9, 2014) to Beijing and was passing through the Seattle airport. I had about 1000 rmb's with me and thought, since I had some time, I could buy a bunch more in the Seattle airport, in the S gates area where my Hainan Airlines flight was departing. I noticed the Foreign Exchange booth was not posting their rates so I had to ask how many yuan she would give me per dollar. She said 5.3. I had a general idea it should be over 6 so said "wow" and kept my dollars. I just got into an ICBC here near my hotel today and got 6.145 per dollar. Maybe most of you know better (I think I usually change in the target country) but I post this here for some searchable content: if you can, buy most of your yuan in China. I traded 800 USD today; had I done so in Seattle, I would have lost 676 rmb. I'll try an ATM next. Greg
