Dear Sir/Madam,I am writing to express my disappointment and frustration regarding the recent flight I took with Ryanair from Charleroi airport to Lisbon airport on 28/03/2024. My flight, FR 3610, was delayed for 6 hours due to technical difficulties of 2 airplanes, causing me significant inconvenience and disruption to my travel plans. I believe that under European Regulation 261/2004, I am entitled to compensation for the delay as the circumstances were within the airline's control. The regulation states that passengers are entitled to compensation for delays of over 3 hours, and in this case, the delay was double that amount.I have had contact with your costumer support many times and they deny my claim for compensation, however no valid reason has ever been given.As a loyal customer of Ryanair, I have always appreciated the affordable fares and good service that the airline provides. However, the experience I had on this particular flight has left me feeling disappointed and frustrated.I kindly request that Ryanair consider providing me with the compensation that I am entitled to under the regulation. I believe that this would not only be a fair resolution to the situation, but also demonstrate the airline's commitment to customer satisfaction and its obligations under the law.I hope to hear back from you soon regarding this matter. Thank you for your attention and prompt response.
