I would be interested to know where the re entry permit office is in the new airport in Bangkok. would anyone have that information and its location please?

Yes, there is a Re Entry application desk AFTER you go through the "International Departures" entry (whereas in DM, it was on this side of the departure entries). Note that as there are several international departure entries, go through the one where you can see the Re Entry Permit sticker on the glass and the Re Entry Permit desk behind the frosted glass. Apparently it is manned 24 hours a day and takes 20 minutes to process (or is it manned 20 mins a day and takes 24 hrs to process??!!).

All this was according to a security guard checking boarding passes at the International Departures entry.

Has anyone gotten a single re-entry at Suvarnabhumi yet? If so, did it take long? (I know it was supposed to be quick at DM, but given the current state of the new airport, want to know.) Am worried as will be flying out in a couple of weeks on holiday, but have no re-entry yet, and am quite a distance from Immigration.
