Just spoke with Rani at Chawla Travel in BKK as I am looking for a decent RTW fare ex BKK, she gave me the following quotes:

SkyTeam 29K RTW = 167,000 BHT
KLM/NW 30K RTW = 187,000 BHT
Star Alliance 29K RTW = 187,000 BHT

None of the above include tax as this depends on the cities chosen.
Seems to be quiet expensive, but that apparently is the going rate at the moment. If anyone has any cheaper RTW alternatives let me know.

Also was curious how to book Ex BKK as I live in SYD and she said I should email her at [email protected] with my itinerary and then she would make the booking, once confirmed I should fax my CC details to her and then she can either send me the ticket in the mail or I can pick it up in BKK.

I'd guess that the 154,000 might have been before the fare increases. I also have the recent full listing thru Maple Aviation and they are at :

Mileage Economy Business
25000 87,000 bht na
30,000 97,990 187,990
35,000 112,690 216,290
40,000 132,290 253,790
Usable on 9w (Jet), AS,CM,CO,EK,FJ,KL,KQ,MA,MH,NF(Vanuautu).NW,PH,SA,S B(Air Caledonie), TN,UL and UX

I'm sure this is the same as being quoted above at Chalwa--I have faxed credit card to Maple Air DBA Continental Airlines in BKK or have paid on arrival. I think it may be possible to find a TA that can do it cheaper.
As noted above the taxes do raise the cost some.
By teh way-booking classes vary a lot depending on airline-- Z (business and B coach on Continental, but full J/C Yon Sri Lanka or Jet Airways
