I am in the beginning of planning a vacation for winter 2003-spring 2004 time period. I would like to take the Mrs from IAD/BWI to Thiland...but I would also like to stop over at one, two, or three other places if it can be worked out. The other places are AMS, SFO, and SIN.

We have @270,000 on Delta...160,000 on CO...and 295,000 with Marriott.

Does anyone have any suggestions as to which airline would make this most doable?

Either business class or coach would work for us.

Thanks
