As the other poster pointed out, the ASEAN airpass must be purchased at the time the international ticket is bought. Presumably, the OP has already bought his/her ticket with SQ.

NOTE: "Asean Air Pass ticket must be issued at the same time with the international ticket for travel into Asean countries on the services of BI/GA/MH/MI/PR/SQ/TG/VN/QV/UB"

And yes, STA may be cheaper. I haven't done the research but when I bought a 3 segment ticket HAN-SGN-REP-SGN with STA last March, it came to about $350. This was on a combo of Vietnam and Siem Riep Airlines.

BTW, STA www site is www.sta.com - I find it easier, though, just to call and work with the agents. They are very friendly and easy to work with.

Finally, just my .02, but I don't think the other poster was attacking you. After all, you were the one to use the "hmmmmm" in your response to my post.

Happy travels to the OP! Siem Riep is a wonderful place as is Vietnam.
