Is it possible to leave the Schengen area a day before my flight will leave? [duplicate]

To get "Airside," you have to pass through the country's Immigration exit check. To get to the Immigration exit check, you must first show your boarding pass and go through security. To get a boarding pass, you must check in to the flight, and be issued a boarding pass by the airline or print it out before you get to the airport. (Some airports switch this, and make one pass Immigration before showing your boarding pass and going through security.)

Both the boarding pass/security check and the Immigration exit check must be open for business and receptive of your entry when you approach them; not all these functions may be available 24/7. Boarding pass/security may refuse your entry if you present yourself the day before the flight's departure.

So the answer to your question depends upon:

• being able to get a boarding pass for your flight the day before it departs; and

• having the airport's security line and boarding pass inspection and exit passport control functions open and operating when you want to pass, and willing to process you long before flight time; and

• having the airside terminal remain open during the time you wish to wait. You might, for example, pass into airside in the evening, hoping to stay overnight and take your flight the next day...but find the airport closes the terminal at midnight, and requires everyone to leave until the next morning.

It seems it could be possible for you to apply for a Schengen Visa Extension.

After applying for the extension you are allowed to stay in the schengen area until you have received any decision. If the application is rejected you'd have to leave within 1 or 2 days.

Applying for the visa extension could be free or cost 30 euro.

I think of this question as "can I stay at an airport without a visa?".

You don't need a visa if you don't pass the immigrations. If you book a flight with a return the next day and you land at the same terminal you are going home from then I guess it should be just fine.

This way you leave at the last date of your visa, which is fine, and you just come back for transit, which is also fine.

• 8th day: you take a plane from Berlin to somewhere
• 9th day: you come back to Berlin from somewhere and then you go to your plane.

This however requires that you only have handluggage.
