i have a really stupid story to share i had a flight out of london to mallorca a few years ago and being the super cautious person i am i showed up 2 hours early and finished checking in and stuff then i had about an hour left so i started reading my book  i got so absorbed in the book that i forgot about the flight and actually missed it  the next flight from this airport was in 12 hours  but there was another flight from a nearby airport leaving soon however you can’t just leave an airport after checking in for an international flight i had to wait for them to escort me out then take a 2 hour taxi to the other airport and finally caught the flight   the worst part - my luggage had gone in the first flight  so it was a nightmare when i landed in mallorca to finally get my luggage the original airline’s office at the airport was closed so i had to come back the next morning for my stuff  i feel you op
