Data sources
Destinations and time zones
City names, alternate names, administrative codes and time zones are enriched with GeoNames data under CC BY. Geographic coverage also uses Natural Earth public-domain populated-place data.
Countries and currencies
ISO country metadata, translations and currency codes are generated from the ODbL-licensed mledoze/countries dataset.
Airports
Airport reference data comes from the public-domain OurAirports dataset. Operational status, schedules and airport suitability must be verified with carriers and aviation authorities.
Exchange rates
Optional comparisons use dated, indicative Frankfurter rates pinned to the European Central Bank provider. They are not card, cash or executable booking rates.
Prices
FarSerene labels estimates as editorial until unexpired supplier quotes cover hotels, activities and transport. It does not present an editorial estimate as a bookable total.
