In Reply to: One way ticket posted by ilab on Monday, 6. April 2015 at 13:29 Bali Time:
I would check with the airport because as far as I know you cannot enter Bali/Indonesia on a one way ticket. I do not know about Malaysia. I have travelled with different airlines each way and was checked at Perth airport that I had a return ticket. I suggest you could also check the archives as this has been asked before and more info would be there.
