Sources used by English content

The catalogue is generated from sources that are actually cited by visible English content. Marketing language from a destination promoter is not treated as independent proof of quality.

Source hierarchy

We prefer the public authority or operator responsible for a fact. Where a source supports only a service description, Seyrio states the travel consequence as editorial reasoning rather than attributing it to the operator.

  • Government and municipal authorities
  • Transport and airport operators
  • Official property or facility records
