Every figure in this guide is traced to a source and to the day it was read. A fact is called verified only when the operator or an official body states it and the check is recent enough.
This page explains the labels, the check windows and what happens when sources disagree.
The Three Labels
| Label | What it means | How it appears on a page |
|---|---|---|
| Verified | The operator or an official body states it, and the page was read inside the check window | “Checked on 9 November 2026 against the operator” |
| Reported | A reliable secondary source states it, or an official source was read longer ago than the window | The source is named and the page does not call it verified |
| Not established | Only comparison sites or conflicting sources exist, or the operator does not publish it | The page says so and, where sources disagree, shows both values |
How Long a Check Stays Valid
| Kind of fact | Check window |
|---|---|
| Timetables, frequencies, single fares, taxi and transfer prices | 90 days |
| Product prices, ratings and review counts | 60 days |
| Rules such as tourist tax, restricted traffic zones and baggage | 180 days |
| Distances and locations | 365 days |
After its window, a fact can stay on a page only as Reported, with the date it was read. These windows are a starting rule and may be revised after the guide has been reviewed.
What Counts as a Source
- Operators and issuers: a railway, an airport, a bus company, a municipality or a booking page that publishes its own offer and terms.
- Official tourism bodies and ministries.
- Journalism that names the decision it reports.
- Comparison sites and aggregators: these can raise a question for the next check, but they never supply an answer.
When Sources Disagree
This guide does not choose quietly. Where two sources disagree, the page shows both values and says which one it follows. For example, an airport page may list a shuttle bus fare of €4.15 while the bus company’s own page lists €5. The guide follows the bus company, because the company sets the fare.
If a source blocks automated reading, for example with a bot check, the guide does not bypass it. The figure is shown as not established.
What This Guide Does Not Do
- It does not claim visits, tests or personal experience. Every page is built from published sources.
- It does not rank options by commission. See the affiliate disclosure.
- It does not state a figure that has no entry in its verification record.
How Dates and Prices Are Written
Dates appear with the month in full, for example 9 November 2026. Times for trains and buses appear in the 12-hour form with the 24-hour time in brackets, for example 3:15 pm (15:15). Tour and class prices are “from” prices per person on the day they were read, and the list price is used where a lower offer was also shown.
