IATA codes are three letters and appear on tickets, baggage tags, and boarding passes — Taipei Taoyuan is TPE. ICAO codes are four letters used in flight plans and air traffic control, where the same airport is RCTP. Every entry in this table lists both.

The table covers 81 major international airports across 46 countries and regions, chosen for the hubs travellers meet most often on tickets and transfers. It is a curated reference, not a complete registry of every airfield in the world.

Large cities often have more than one airport, each with its own code. Tokyo has Haneda (HND / RJTT) closer to the city and Narita (NRT / RJAA) further out; Taipei has Taoyuan (TPE / RCTP) for most international flights and Songshan (TSA / RCSS) in the city. Match the exact code on your ticket rather than the city name.

Yes. The search box accepts airport codes, airport names, city names, country names, and timezone text, so you can go from LHR to London Heathrow or from the name Heathrow back to LHR. You can also narrow the list to a single country with the country filter.

Each airport lists its standard UTC offset, covering 17 offsets across the table. It helps when reading an itinerary or estimating arrival time after a transfer, but it does not track daylight saving changes, so confirm local time for date-sensitive connections.

No. This is static reference data: airport name, codes, city, country, timezone, and a short location note. It does not include flight status, terminal maps, security wait times, visa or customs rules, or temporary closures. Check with the airport, the airline, or the relevant official source before making time-sensitive decisions.
