USA here, 3 years ago (2021) I accidentally overstayed the Schengen area by 1 day (91/180) because I had a suddenly cancelled flight (Origin Gran Canaria Spain), bought a ticket for the next available one (Layover in Portugal) but couldn't enter the passport gate until right before the new flight. I was stamped out without any obvious fanfare or restrictions, even if I, in a panic, did disclose what had happened after realizing what happened. The border guard simply smiled and said "that's alright, but never do it again, you can come back next year" and I was given no obvious ban or fine.
The next few years I was still being allowed in each time, one border guard only taking a pause for a second one time when looking through my passport (maybe calculating days?) but never said anything so I can only assume it WAS flagged in the SIS/VIS but was overlooked because of previous travel history or something..?
I travel to Europe to see family yearly and on subsequent visits, I left way more time on each so that if something like that were to ever happen again, I'd be well prepared and would never even have the CHANCE to overstay and break the law. I always have insurance and exit tickets booked at the same time as entry, and carry existing records with me when traveling.
That said, I'm worried about the EES/ETIAS systems being implemented because I'm well aware that any flag in the system can definitely mean that my applications and entry could easily be revoked/rejected in a similar fashion to the USA'S ESTA. I'm terribly sad that I made such a dumb and uneducated mistake and I've done a lot to ensure that it never happens again. I've seen many others do the same thing accidentally for a day or so, just about as unaware as I once was, and I'm wondering for their sake as well. Will travel simply be revoked for that many individuals?
Error or not, this does imply that I would be automatically excluded from getting the ETIAS, does it not? I'm also aware that the UK's ETA already has a digitized system for such things but I'm not exactly sure what their process is or how such things are handled for previous records prior to it's implementation.
Yes, I am fully aware that I did something stupid. I've tried asking elsewhere for opinions and advice but often get called "entitled" and "stupid" or mocked for my nationality if I even so much as mention it. I'm not here to break the law or skimp the rules or find any specific way to do so. I am however aware of a bilateral agreement that involves Spain, Portugal, the USA, etc and extended the 90/180 days, but I'm not interested in attempting to bring that up to argue my case, as rules are indeed rules.
Anyone have any help/opinions? Thanks so much for reading.
