Surprisingly, I received a call this morning from the lady at Orient Thai airlines and she had worked with her main office to secure access to another ticket on the special test flight they will run July 29th from the old Bangkok airport to the new one.
See the entry below for more details.
So I walked on down to the ticket office to secure my ticket, ignoring the light spits of rain that were beginning to fall.
By the time I walked back twenty minutes later, the light spits were a steady light rain and I was pretty wet. But at least I have my tickets! Yeah! 
Picture right: me, wet and blurry.

ryc: hey chris, yeah, actually, I don’t know where to stay while in BKK, so if you could give me some recommendations, it’d be greatly appreciated. I’ll only be there for a night, so somewhere close to the airport and cheap would be best. Thanks!
