The below Parliamentary question was asked by Barry Sheerman on 2016-03-08.
To ask the Secretary of State for Transport, what data his Department collects on drunkenness of passengers on commercial flights.
Mr Robert Goodwill
The Government does not collect specific data on the frequency of incidents involving drunk or aggressive passengers.
If serious enough such incidents would be counted amongst data for safety related events. In accordance with (EU) Regulation No 376/2014, safety-related events which endanger or which, if not corrected or addressed, could endanger an aircraft, its occupants or any other person have to be reported to the Civil Aviation Authority as part of the Mandatory Occurrence Reporting Scheme (MORS). The Regulation requires that the reporting, analysis and follow-up to such occurrences remain confidential. However, the Regulation does permit information to be released on request to interested parties that have a genuine safety related need for the information.
