I went through the new airport (as SLF) for the first time this weekend and got to see the shambles first hand.
The check-in arrangements for StarAlliance/Thai seem to be woefully inadequate - by 6am queues stretched outside the terminal. Only the need for wheel chair assistance made it possible to get through the process in sensible time, even this required a 90 minute wait. Some pax were taking 2.5 hours in the queue.
