Aer Lingus has cancelled almost 400 flights due to ongoing industrial action by pilots, with another 122 flights cancelled up to 7 July. The indefinite work-to-rule and strike action have caused chaos for passengers, with an eight-hour strike planned for Saturday. Talks to resolve the pay dispute have failed, leading to further uncertainty. A group of students and teachers from Shimna Integrated School were left stranded at the airport when their flight was cancelled, receiving little support from the airline. Despite the pilots' reasonable pay claim, further strike action may be on the horizon if negotiations do not progress. Passengers are advised to check the Aer Lingus website for a list of cancelled flights and to explore alternative travel options.
