Editorial Standards & Data Verification Policy
Good travel planning depends on knowing what a number means. Here is how we record sources, label editorial estimates and flag information for another review.
1. Sources and planning estimates are different
Prices and rules should link to the relevant operator, venue or public authority. Editorial budget allowances are planning choices, not live quotes or measured averages, and link to our methodology rather than being presented as independent evidence. Useful external sources include:
- An official governmental or border control resource (e.g. EU Schengen portal, national consulates).
- An official public transport operator tariff (e.g. Deutsche Bahn, České Dráhy, ÖBB, Renfe, CP).
- A dated receipt or booking confirmation that the editorial team can document and check.
2. Dynamic Expiration & Review Intervals
Our data health dashboard flags records when they reach a review deadline. A deadline does not mean that a new check has been completed. The usual review windows are:
- Transport fares and route options: 90 days.
- City budgets and accommodation: 120 days.
- Baggage limits and entry rules: 180 days. Always check the official source before travelling.
- Rail passes and night-train benchmarks: 30 days.
3. Public Verification Badges
“Source checked” means an external source was recorded and checked on the date shown. “Editorial planning estimate” identifies a chosen allowance or internal benchmark, not an independently verified market price. “Review due” means a dated record has reached its review window. When source evidence or a review date is missing, the label says so instead of implying that a check happened. None of these labels confirms live availability or the price for your dates. Publication dates, content changes, source checks and editorial-estimate dates are separate records.
