I got in february a Beijing-New York- Miami-PR ticket for $1,800 USD.

I dont think you were ripped off.

I usually roundtrip from Shanghai to one of various cities in the US via Los Angeles or Chicago.  I always fly American Airlines so I can rack up the frequent flyer miles.  The going rate's been about $1000 +/-, although prices have started to creep up a bit lately.  $1300 seems a bit high, but then again I never fly from Beijing.  I also find the routes going through LA are a bit cheaper than going to Chicago....usually.

One tip is if you think the price for your ticket is too high...don't buy it right away.  Wait a few days and then check again.  They change the prices on their website frequently, and I usually can't make any sense of why.  For example, I checked on a flight from Nashville to Raleigh-Durham: $376 roundtrip.  Waited a couple days and the exact same fare was $208....um, ok.

Actually that is about the right price range, actually flying in April is cheaper if you use a Chinese airline, I got a round trip ticket from Beijing to the states for about 945US using a Hainan Airlines

789 but you have to take Boston to air Canada to Beijing or shanghai during the summer, i do not trust Canadian air lines for some reason i think it is because you never hear about them. yah but do it through a Canadian air line i think i have even found cheaper but keep in mind all these tickets are economy 

I got a one way ticket for around 500 dollars....from China to the East coast of America. 

what's the best time to travel from Shanghai to Miami ? Which company sell the lowest tickets ? which ticket online company is the most safest to buy tickets ? wait for ur advice.
