No, I was talking primarily about check-in.

And if you read posts I and others have made here, we've warned that when travelling to the Philippines and Indonesia in particular, you can expect to be asked for a ticket out at check-in. But in other circumstances -- NO MATTER WHAT TIMATIC SAYS -- my first-hand experience and those of others posting here is that the real situation is very often far more relaxed, but with no guaranty in any given case.

Have you actually travelled in Asia with a one-way ticket? I have, and I have never been refused boarding.
