What's new

Version 4.0.1 · Jun 10, 2026

Small content update — accuracy improvements: - Corrected several delay codes that were previously mislabelled, bringing them back in line with IATA / EUROCONTROL (AHM 730) standards. Most notably, code 87 is now correctly "Airport Facilities" (previously mislabelled), and codes 09 and 94 now use their correct alpha codes (SG and RS). - Improved descriptions and corrected category placement for codes 19, 22, 23, 24, 26, 27, 28, 39, 41, 42, and 48, amongst other codes. - Added code 29 – Late Acceptance (Air Mail), which was previously missing. - Various spelling and wording fixes throughout the code library. A big thank-you to everyone who sent feedback — we read every email, good and bad, and they genuinely help us make the app better. Keep them coming!
