A practical guide to airport codes and what they mean
LOS, ABV, LHR, JFK — learn why three-letter airport codes matter when you search, book and manage a journey.
Airport codes are short location identifiers used throughout aviation. IATA three-letter codes are the ones travellers see most often on tickets, baggage tags and flight searches. Learning the codes for your origin, connection and destination helps you avoid confusing airports in the same city. Before paying, always re-check the airport name, city, terminal information and connection time. AviationInternet is being designed to present both the code and plain-language airport name together, so travellers can book with more confidence.
