Just came through said airport 4 hours ago.
Check in fine. Queues at security much reduced - possibly because it was not my normal 6 o'clock check in.
Don't try to eat or drink beyond security unless you have an hour to spare.
As far as flying was concerned. Took off 5 minutes before scheduled time and arrived at PIK 25 min ahead of schedule. Difficult for STN to claim credit for that bit though.
