Hi Cx flyboy,
could you confirm which B737 series you saw in BKK?
This is because there was a B737-200 with a palm tree on the tail and a very colourful cheatline - it belongs to Phuket Air, a new airline that is to start operation on 19 Dec (last I heard yesterday, it was due to begin on 1 Jan 2002).
You could get a glimpse of this aircraft at http://www.phuketairlines.com
The aircraft is right now in Ranong in South Thailand and is scheduled to return to BKK this evening at 1700hrs.
