My wife and I are taking a few flights later this month that all go via Singapore, but with different carriers for each leg (all booked as separate return trips). Therefore, we have to collect baggage, go through customs/immigration, check-in for the next flight, and go back through customs/immigration again.
We'll be doing this three times over the course of about 2 weeks.
The first time there will be overnight stay in between, which of course isn't that unusual, but the second and third times there'll only be 4 hours in between each. Essentially this means we'll end up with 6 stamps in our passports over a really short period of time.
As Australian citizens we get 90 days visa-free on the spot, so that's not a problem. But are all these entries and exits likely to cause any problems? If so, how should we be prepared?
