I have been due to traveling from Turkey (Turkish Citizen-Non EU)) to Hungary. I was rejected to board the plane because my passport expires less than 3 months at the time of travel(departure time). (Although I have a return ticket one week later.) I didn't know that many countries require the passport have at least 3 months validity at the time of entrance ( I have a special passport; it doesn't require any visa to most countries) I was planning to fly Pegasus Airlines (Turkish low-cost airline).
I wonder what the situations are in other countries. Do Other airline companies let their passengers to fly and leave up to chance that the passenger cross the border. Has anybody been rejected of the entrance to the country at the custom office due to this rule? What happens somebody show up at the custom office with a passport less than 3 months of expiration date. Do the custom offices take this situation lightly at the border and let the passengers have the entrance to a country?
