I received a short term visa for the Schengen zone, and I planned my trip so that my return flight is scheduled exactly the day my visa expires.
The visa duration is 20 days, and I stay exactly 20 days, including the day of arrival and departure.
I have the confirmed return ticket, which departs from the same airport, at about 10AM. the same airliner has a few other flights later that day.
Are there any negative effects if I stay the maximum allowed duration of the visa? Any problems due to lack of time to arrange alternative transport?
I'm pretty sure the flight wouldn't be canceled, but since the airline has flights later that, "I am" convinced that I will be able to exit the zone in time. Do immigrant officers care about such cases?
(I have a travel insurance and the airliner is Qatar airways if it makes a difference).
