Questions about the IATA database airlines and travel agents consult for traveler documentation requirements such as passports and visas, health and vaccination certificates, airport taxes, and customs and currency restrictions.
IATA Timatic is the most commonly used database used by airlines and travel agents to verify passengers' paperwork is in order for customs-and-immigration at their destination and any intermediate stops.
Based on the traveler's nationality, country of residence, destination and transit points, and so on, Timatic will return requirements relating to
- passports, visas, and similar documents
- certificates for vaccinations or other health matters
- airport taxes
- customs restrictions
- currency
Although not a governmental resource, Timatic is almost universally used by international airlines. Thus, what it reports is what airline staff will use to determine whether or not a passenger will be allowed to board in practical terms.
Questions tagged as timatic should be focused on the database and system itself; general questions about travel documents should use the appropriate tag.
