We have found TG flights MXP - BKK. Not entirely sure that we want a stopover in BKK as would prefer to go straight on to SIN then have a stopover in HKG on the way back.

Question I have is whether the hefty BKK departure tax is lower if you are only transitting through BKK. We would only change planes as would be booked TG all the way through to SIN.

I suspect the answer is no but thought I would ask!
