So I couldn't buy it on the Air China site for South Korea. I explained this to the woman at the US Air China number that I called (they don't have a number for South Korea). She asked me what site I meant, did I mean southkorea.com? I have never talked to anyone so clueless about the company that they work for in my life. When the last 2 agents I spoke to didn't understand what I meant they just hung up.
Anyway, she offered me a flight for $356 when the one on the site was $120. Travel agents offered me one for $160.
I finally decided to book with another airline on Expedia. I honestly cannot believe I wasted so much time and money trying to book this flight with Air China. I didn't want to fly with them after that!
