Skyteam offers a Air Pass for Asia(SkyTeam Asia Pass) and China(SkyTeam China Pass), but it gives only two Skyteam Airlines in the Asia area(Korean Air and China Southern). The Asia Pass is only interessting when you want travel to/from Korea/China, a skyteam intercontinental ticket is required to get the Asia Pass and the Maximum stay is 60 days(from the intercontinental ticket). So you canīt visit all the countrys you want and musst fly back to the USA after 60 days. For the China Pass(China Southern) a international ticket with Sykteam to China is also required and also a Maximum stay of 60 day. The Price for the China Pass, is not rellay cheap in my opinion.
