Software flaw misclassified women as children on Tui flight

A software flaw in Tui's reservation system misclassified 38 adult female passengers as children due to a language difference where 'Miss' is used for children in the programming country. This led to incorrect weight calculations for take-off on a flight from Birmingham to Majorca on 21 July 2020. The AAIB report stated that the safe operation of the aircraft was not compromised, and Tui corrected the fault.
