Flight Diversion to Glasgow Prestwick - FR25 Paris Beauvais to Dublin
Flight FR25 from Paris Beauvais to Dublin (today 12th April) was diverted to Glasgow Prestwick on the instruction of the UK Department for Transport, where it landed safely at 14:22. A note was passed to the cabin crew onboard claiming that there was a bomb onboard the aircraft. The Captain immediately reported this to the UK ATC and was instructed to divert to Glasgow Prestwick Airport.
All passengers together with Ryanair are co-operating fully with the police and local safety authorities. The aircraft will now be subject to a detailed search, following which we expect it will be cleared to travel onwards to Dublin.
Update at 16:25 hrs; Prestwick airport re-opened.
Update at 16:45 hrs; Strathclyde police authorities have now authorised passengers to disembark from the aircraft. All passengers will be taken to a segregated room in the terminal building where they will be met by ryanair staff and provided with refreshments and other facilities. Ryanair is awaiting further instructions from the Strathclyde police as to when the passengers and the aircraft may be cleared to safely return to Dublin.
Update at 17:15 hrs; Strathclyde police authorities are now interviewing all passengers individually. In addition the aircraft and bags are being inspected by security services. Once this has been completed and the aircraft released for service, Ryanair have arranged for a stand by crew at Prestwick to bring the aircraft and all passengers safely to Dublin. As in all such cases Ryanair is co-operating fully with all directions made by the Strathclyde police authorities.
Update at 19:00 hrs; Strathclyde police are continuing to interview the passengers, and the detailed inspection of the aircraft is expected to be concluded shortly. Subject to the plane and passengers being permitted to travel onwards by the Strathclyde police, Ryanair is preparing for an onward departure to Dublin at approximately 22:00 hrs this evening.
Ryanair apologises sincerely for any inconvenience caused to these passengers, however the safety of our passengers and aircraft will always be our number one priority. Further updates will be posted on
