Ok.. So on the advice from members of this group, I decided to book travel from BKK to BKK by way of KUL. I understand I can get off the plane, stay in the international arrival section and catch my plane back. HOWEVER, I may have goofed because I booked with two different airlines - will that make difference? Can I check-in while in the arrival check-in? Will I need a printed boarding pass?

US passport holder, multiple entry tourst visa.

(Robert before you turn-off commenting .. this is a visa related question because: A) my passport is full of Thai Visa and therefore I need a new one, and KUL is the fewest stamps to do a border bounce. B) I have other reasons that i don't recall right now)
