How we check our information

This page last updated .

Travel document requirements are the kind of information where being approximately right is not good enough: if we tell you your paperwork is in order and we are wrong, you miss a flight. So this page sets out exactly how the information on this site is produced, and what we do when we are not sure.

Where the information comes from

Official sources first
Every requirement we publish is checked against the authority that sets it: the European Commission for EES and ETIAS, GOV.UK for the UK, and the relevant national authority for anything country-specific. Where an official source answers the question, that is the source we use and the one we link to.
Operators for what officials don’t publish
Officials publish the rule; they rarely publish what happens at 7am at a particular terminal. For that we use airport and carrier operators — Berlin Brandenburg, Munich, the Port of Dover, Eurotunnel, Eurostar — and we say which one told us.
Press only for what nobody official has confirmed
Some things are only reported, not published: a delay, a queue, an industry request. We use reporting for those, we name the outlet and the date, and we do not present it as settled.
Every volatile claim carries the date it was confirmed
Anything that could change between visits is dated on the page itself, not just at the top. If a section says “confirmed 8 September”, that is the day we could last verify that particular point.
When we cannot confirm a change, we say so
This is the rule that matters most. If we re-check and cannot establish whether something has moved, we leave the old date and say we could not confirm it. We never refresh a date to make a page look current. A status page with a date that is not true is worse than no page at all.
Two sources for any future date
Dates that have not happened yet are the easiest thing to get wrong, because old timetables stay online and read like new ones. We check the publication date of anything announcing a future date, and look for a second source, before it goes on the site.

How often each page is re-checked

Monitoring — every day
We run alerts on the official sources for EES and ETIAS and check them daily. Checking and publishing are two different things: most days nothing has moved, and on those days the page correctly stays as it is.
Status pages — updated when something changes
EES status and ETIAS status are rewritten as soon as the answer they give would change. Each one shows the date it was last updated and keeps a change log, so you can tell the difference between “nothing has changed” and “nobody has looked”.
Guides — when the underlying rule moves
Pages like EES with children and the UK ETA for children cover rules that are stable. We re-check them when the rule changes rather than on a calendar, and they carry the date of the last check too.
Corrections — as soon as we know
If we get something wrong we change it and record it in that page’s change log. We do not quietly edit and leave the date alone.

What we are not

If you find a mistake

Write to info@viaryo.com and tell us what is wrong and, if you can, where the correct information is. We would much rather be corrected than be wrong in public. Corrections go into the change log of the page they affect, so you can see what changed and when.

Who writes this

VIARYO is a small team building a product for travellers, and these pages are written and checked by that team. We are not journalists and we are not officials. What we can offer is that every claim on this site is traceable to a source with a date, and that we would rather leave a question open than close it with a guess.

You can see the method in practice on our EES status page, where the sections that change most often are dated individually and the ones we could not re-confirm say so.
