BTW, meadowfield, you do not need to contact CX in each country to do your booking.. you may in fact do your entire booking with CX from where you're at now.. and just issue the ticket with them when you get to BKK. It's better that they have the entire intinerary with them when they issue the ticket. If you decide to leave any segments OPEN, you'd have to tell CX as well .. so that they know.
