SkyKaki

The app ships with a short airport list. To search every airport, add the OurAirports file. This page cannot download it for you, so it takes two steps:

• Download airports.csv (about 12 MB) to your phone.
• Tap "Choose airports.csv" and pick the downloaded file.

OurAirports data is public domain and comes with no guarantee of accuracy. Each result from it shows the date you loaded it and a link to check the code officially.

• Airlines: airlines, read from Wikipedia's "List of airline codes" on 10 Nov 2026. Wikipedia is not an official source.
• Singapore connections: every passenger airline and destination in the "Airlines and destinations" table of Wikipedia's Singapore Changi Airport article on 10 Nov 2026 ( airlines, airports with codes). Routes change often, and the article can be out of date. Cargo airlines are not included.
• Singapore gaps: ten airlines (Aero Dili, Batik Air Malaysia, Citilink, Myanmar National Airlines, Peach, Pelita Air, SCAT Airlines, Sun PhuQuoc Airways, TransNusa, Trinity Airways) take their codes from each airline's own Wikipedia article, read on 11 Nov 2026, because the code list did not have them. Newark, Phnom Penh, Siem Reap, Nha Trang and Ulaanbaatar are linked to their airlines using each airport's own Wikipedia article, read on 11 Nov 2026.
• Airports: airports, read from Wikipedia's busiest-airports and ICAO-code lists on 10 Nov 2026, plus the OurAirports file if you load it.
• Aircraft: ICAO type designators, read from Wikipedia's "List of aircraft type designators" on 10 Nov 2026.
• Aircraft seats and facts: typical and maximum seat counts and one fact per aircraft family, read from each type's Wikipedia article on 11 Nov 2026. These are general figures for the type. The app does not hold any airline's own seat layout.
• Reg: aircraft registration prefixes from FAA Order JO 7340.2P (a US government list of the marks notified to ICAO), read on 10 Nov 2026. Type a full registration such as 9V-SKA, a prefix, or a country. The Aviation Codes Central table is not copied in, because the site shows a copyright notice and no reuse terms. Twelve prefixes that appear there but not in the FAA list (VN for Vietnam is one) are included as labelled, unverified fallbacks.
• Not checked against IATA or ICAO. No entry here has been confirmed in an official register. Use the "Check official" link on each result.
• IATA code search: not imported. IATA's terms allow personal look-ups only, and bar redistribution and use with AI tools.
• ICAO Doc 8643 and ICAO data service: not imported. The data needs registration and an API key (100 free trial calls, then paid), and ICAO's site reserves all rights.
• V2 additions: tap-to-explain labels, a flight number decoder, country flags (worked out from each entry's country name), favourites saved on this phone only, a Learn tab with a quiz, flashcards, a made-up boarding pass, a radio speller and a Singapore/Zulu clock. The quiz and flashcards use only the data above. Explanations are written for this app; each shows its source.
