Vienna airport boasts the minimum connection time as low as 25 minutes, "the fastest in Europe" as they claim. And Austrian Airlines frequently offers flights that are 25 minutes apart, including non-Schengen to Schengen flights. And sometimes it changes the schedule for already booked flights bringing them closer to 25 minutes.
In reality, when traveling from outside Schengen it is not possible to make this connection in less than 15 minutes, at which point the gate is closed. To get from non-Schengen area to Schengen area - even if you're the first at passport control and it only takes a minute - you need to walk quite a lot. I did this route three times, every time taking quite long walk which was no shorter than 15 minutes. And I was always the first at (empty) passport control and RAN all the way through - and I'm pretty sure that most passengers won't make it even in 25 minutes.
Every time I flew this route (OTP-VIE-SZG) I missed my connecting flight. Of course I collected compensation and got free overnight stay or a Mercedes taxi ride to Salzburg, but I'd rather be at my destination on time.
Is there a procedure where I, as a traveler, can challenge the airport's claimed "minimum connection time"?
