Choose the relevant Aer Lingus request
Aer Lingus lists separate compensation and expense routes on its requests and enquiries page. Use the request matching the remedy you need. For example, a reasonable hotel invoice supports an expenses request, while the itinerary and cancellation notice support the fixed-compensation assessment.
For an agent booking, retain the message the agent received as well as the message forwarded to you. Establishing the notification timeline can be important after a cancellation. Preserve the full through itinerary when a Dublin connection was involved.
When Aer Lingus owes UK261 compensation
Check Aer Lingus coverage, timing and the cause using the UK261 checker. For the shared rules, including cancellation notice, rerouting reductions and separate care rights, read the UK261 guide. This page focuses on the airline’s claim channel and practical evidence.
Official claim channel and escalation
Start with Aer Lingus customer care / flight disruption claim route, filed with the booking reference and operating flight details. Include booking reference, flight number (EI), scheduled and actual arrival times, a short timeline, and receipts for meals, hotel, or transport if duty of care was not provided.
This airline is not listed in the CAA-approved UK ADR scheme tables checked for this guide. Start with the airline claim channel; if the airline will not resolve a UK-covered complaint, the CAA Passenger Advice and Complaints Team is the practical escalation route, although it cannot issue the same binding decision as CEDR or AviationADR.
ADR membership was checked against the CAA table on 2026-10-03. Airline forms move, so search the airline's own site for "compensation", "flight disruption", or "customer relations" if a saved link is stale.
Excuses to challenge
Aer Lingus may point to weather at Dublin, ATC restrictions, US preclearance disruption, late inbound aircraft. Some of those can be extraordinary circumstances, but the label alone is not enough. Ask what specifically happened, when it affected your aircraft, and why the airline could not avoid the final delay with reasonable measures.
For UK to US itineraries via Dublin, check whether both legs were on one booking. A missed connection on one ticket can be assessed by final-arrival delay, not just the first leg.
UK route notes
Aer Lingus UK claims commonly involve UK-Dublin feeders and transatlantic connections where the final-destination delay is the key evidence point.
An Aer Lingus itinerary through Dublin can involve an Irish Sea feeder, a transatlantic connection or separately purchased tickets. Keep both boarding passes and the original through-booking confirmation. A Dublin-to-UK service on an EU carrier may fall within both EU261 and the UK arrival coverage described by the CAA; do not seek duplicate compensation.
