I just booked:
IAH-NRT-SIN on May 3rd. Arrive SIN at 1am on May 5.
Then return SIN-NRT-IAH at 5am .
Question: what is the custom process at midnight at SIN?
Is it possible to get boarding pass for the return flights? between the 1AM arrival and 5AM departure for return, without having to clear immigration to get out to the ticket/checkin counter?
The transit desks (excep for SIN) are usually closed between those hours (1-5AM)!
