As mentioned in another question I hope to fly one way from Istanbul to Seoul on a one way ticket in the next few weeks, then while I'm in Korea decide whether to fly directly home or get a visa for China and come home that way, since there are lots of cheap flights I could use.
I know that officially people must have a return ticket or an onward ticket to be allowed to enter just about any country.
I also know that for many countries this rule is seldom enforced and many people travel around the world on all one-way tickets.
In researching this question I have read that it is up to the airline at the at the airport you board your flight to pre-screen people to make sure they have such return/onward tickets, and that airlines may be fined for any people the destination country rejects.
Personally I have never been asked to show a return or onward ticket in an airport at either departure or arrival (I have been asked for it when extending a visa at the immigration office in Mexico).
What I want to know is "Is Etihad known to strictly enforce this rule?" (At least from Atatürk Aiport in Istanbul if it makes a difference?)
