Huh..? Salzburg is pretty small and so is its airport. What route would you have to take that you end up in a small, barely international airport and not realize at your last transfer that you were in the wrong part of the world?
Stupid people who put literally no effort or attention to anything they do, ever. Same kind of people that don’t bother to reserve a rental car ahead of time.
It's not like reserving a car ahead of time actually does anything, except maybe get you a discount. Not once has the rental company actually had the right car available for me. Usually I get "upgraded" to an SUV or something that costs me 1.5x in gas over the trip.
During COVID lockdowns when the US border was closed, something like 16,000 Americans attempted to go to Canada and were turned back at the border. This was in the news. So I have no trouble believing this.
Trying to get into Canada during a pandemic and booking a flight to a different country because some letters are off on the country name are highly different things though
Barely international? I'd say Salzburg is about 99% "international". Remember, a flight from Kempten to Salzburg is "International". Flying from within the rocky backwater proud and vast country of Austria to any other part of the country would probably take longer than just taking a train.
