Buying on line is still the cheapest way to go. The price is always cheaper due to the fact you are not using the service of a person. Or a travel agent. But still look into it. you never know what you will find.
I have purchased to tickets to China. Both cost me around 900-1,100 USA. I like to use BOOKING BUDDY

This website will let you search all the major airlines and discount airline ticket sellers.
If you buy a month in advance you will get a cheaper rate. If you buy a week in advance you will pay more. If you leave on a Busy travel day (SUNDAY) it will cost more. If you leave on a not so bust travel day (TUESDAY) it will be less. Most likely if you buy close to the time you are going you will pay more.
Good Luck.
