Sorry I wasn't more clear civic. I am familiar with the All Asia pass at $999, but that doesn't allow me to earn miles. I am going to purchase a ticket over the pacific to earn those miles and was looking to purchase another seperate ticket just for Asia.

I found what I was looking for, it is called ASEAN. It isn't unlimited, you just purchase segments. The problem is you have to fly in on a Star Alliance Carrier.

Bangkok Air offers a deal for $50 for domestic and $80 for international segments that we are interested in. We could fly into Bangkok then hit Laos, Cambodia and Vietnam for less than $300.
