I'm with you on that, the reason I would consider going to Thailand would be best if I left the wife here in the States!

Okay, this occured back in '88, so it very well may have changed. My wife and I got married in Korea while I was stationed there. She traveled from the U.S. to Korea on a passport with her maiden name. We registered the marriage @ the U.S. Embassy and they provided her with documentation on her passport showing her name had changed - but she kept the same passport and tickets home with her maiden name (the passport still showed the maiden name).

I don't know if that helps, but it's all I've got to offer. Definitely check with the State Dept. AND the airlines.
