Overview
- A dispute on a delayed Marseilles-to-Dublin flight on April 9, 2024 began when a senior cabin crew member is accused of denying a passenger use of a toilet and leaving him in tears.
- Aer Lingus dismissed the crew member, Alan O’Neill, for gross misconduct in October 2024 after an internal investigation and appeal process concluded he had behaved in an unprofessional and hostile way.
- The Workplace Relations Commission held a six-day hearing in which Mr O’Neill did not give evidence or call witnesses and was told to have issued a formal disruptive-passenger warning to the traveller.
- Adjudicator Michael McNamee ruled on June 19, 2026 that the disciplinary and appeal process was fair, the employer had reasonable grounds to conclude trust and confidence were eroded, and dismissal was a proportionate sanction.
- The ruling leaves Aer Lingus’ sanction intact despite union support for Mr O’Neill and his later re-employment, and it reinforces that airlines can lawfully dismiss staff for conduct judged to threaten passenger safety or customer trust.
