I suggest you book a one way ticket back to Chile and show that you're leaving before you get caught and screwed over a treat. Personally speaking, if you do manage to get out of Finland unscathed, I hope that the UK deny you entry.
It is NOT "illegal" for the airlines not to ask for onward travel proof. That is apologizing for certain airlines who cheat their passengers, and for certain travel agents who are happy to pocket extra commissions. Nobody has yet to be denied entry for that reason, no airlines have been forced to fly anyone int his situation back for free, and the airlines KNOW it.
Your plan may not work as you are visiting Israel.
If you go to Israel you will be denied entry to Lebanon and Iran. Yes, it is possible that using the KHB might keep you from having evidence of an Israeli visit, but that's not guaranteed and if it doesn't work then the rest of your plans are shot.
I do appreciate the information, but not the condescending tone and manner in which it was delivered. "You need a reality check- the world is not your oyster" really?? How about just saying "Your plan would not work as you would likely be denied entry upon arrival... Look in to the following alternative approaches..."
Really? It says on the embassy website that you may be refused entry on arrival if you do not have a return flight pre booked.
It would be incredible if what you say is true but I'm slightly concerned about the (expensive) hike back to the UK if I get denied on arrival.
Just to point out that you haven't been "denied entry" - you have been refused a visa because your connections to your host country are weak. What evidence can you produce that shows you have some connection to Kuwait
"It was both the airline at check-in and also Immigration officials at the entrance to the boarding gate/waiting area"
Weren't the immigration officials being helpful to confirm that you won't be denied entry by the Koreans? Weren't they being proactive to ensure they won't process you again?
"You could have a problem with entry to Canada. Any arrest is a problem with them. " Yes but the OP was never called to appear in court nor was convicted of a crime. So how can that be if there's NO record to prove that the OP was ever arrested. (S)he can just not disclose or deny if asked. How would Canadian immigration authorities know?
US citizens cannot be denied entry to the US, but without a passport or some other authorzied form of identification the person will be detained until their citizenship is verified. The horror stories Tired/Retired mentions I am sure are about the detention process.
No.
If you have an Armenian visa, you might get a little hassle at the border (a few extra questions) but they'll let you through. However, if you have the Nagorna-Karabagh permit in your passport, you will 100% be denied entry.
