Possible duplicate of Left UK without passing through Immigration, why?

@phoog My question is not about WHY i left without leave stamp. My question is WHERE do I check if my information is passed and my is registered. Its not a duplicate.

Ok, I've retracted my close vote. I don't think it's possible to check, but it might be. The airline's systems, though, surely work directly from their boarding pass records, and do not depend on how you checked in. The information doesn't pass directly from the online check-in system, but rather from the boarding system into which your check-in data was passed by the third party. They have to be sure not only that you checked in, but that you boarded the plane and were still on it when it left the country. That's one reason why they scan boarding passes electronically.

It depends how I checked in.. What if (well I am a bit paranoic) I made a mistake while entering my visa number? In that case UK immigration service will think that I break the rules? They scan my boarding pass - yes, they do not scan my visa info, so possibly there might be a situation when passenger wants to edit that info?

They will match your record with your passport number. That's why they scan passports electronically as well. They did scan your passport electronically before you boarded the plane, didn't they?

@phoog no, they did not e-scan my passport. I entered via my boarding pass QR code

@NeilGaliaskarov If did the airline didn't scan your passport, how did they know that you would be admitted by the immigration authorities at your destination?

@phoog I do not know :) I am not an airline representative. Thats why I feel a bit anxious about my leave

@phoog in my experience, never showing your passport to a human is not unusual when boarding a flight in the UK

which is somewhat surprising given the number of airlines that charge for name changes

@NeilGaliaskarov Well as far as immigration violations are concerned, even if your departure was not recorded, you can use other evidence such as your admission stamp in your country of destination, to show that you left the country.

@CMaster For international flights?

aye

although probably within EU mind

I certainly got asked repeatedly if I had an ESTA for flying to the US

this is only when checking in online mind

you provide your passport number to the online checkin service

any "at airport" check in, they require passports (or ID cards) before issuing the boarding pass

@CMaster And what if you type it incorrectly?

I suppose they would catch that when they verify the passport details with the destination country.

But I doubt the US would be happy to know that a person could board a US-bound flight in the UK with someone else's passport and ESTA authorization.

@NeilGaliaskarov This of course is only an issue if you try to enter the UK again. If they have no record of your departure, and you claim to have left in July 2018, they might ask you to prove it.

if you type your passport number incorrectly I presume it gets flagged up, and either the boarding pass is never issued in the first place, or is revoked when they have to submit the advanced passenger information and find it doesn't match up

@CMaster If I remember, I'll try that the next time I'm in the UK.

and as said, I think I've only seen this level of casualness on intra-EU flights

but if you do online check in, no bag drop, then the first encounter you have where somebody could check is boarding the plane

@CMaster Oh, I guess I misconstrued your "asked repeatedly if I had an ESTA for flying to the US" comment. You were also required to show your passport at the airport in that case?

yes

I see.

and normally they check passport + boarding pass on boarding

but I have seen that step skipped to just BP

@CMaster Does the "normal" passport check include scanning the machine readable data?

inconsistent

Hm. Could the inconsistency be explained by varying API requirements of different destination countries?

I'd say most of the time its probably visual inspection of passport + scan of boarding pass, but I think they may have captured machine-readable passport details

I'm getting on a flight later today, but its purely domestic so I don't imagine that will be too helpful on this question

Indeed. I just find this baffling in light of the exit check system's reliance on airlines to collect passport data.

@CMaster in my experience with flights to and from the US, which similarly relies on API data for exit control, it's impossible to board without having your passport scanned. Although I do frequently leave the US with a foreign passport that I've never used to enter the US, and that's never been a problem.

I should try filing a freedom of information request to get the exit records for that passport, if they even retain them. I would be curious to know whether they have any procedures for exit records that don't match an entry.

Probably I will go to the airlines office

And will request changes
