For Aer Lingus, the operating carrier matters. If you booked through a partner or travel agent, submit the compensation claim to the airline that actually operated the disrupted flight, not necessarily the brand that sold the ticket.

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.
This page was checked against the CAA ADR table, CEDR, AviationADR, and airline support pages on 2026-07-08. 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.
Aer Lingus UK claims commonly involve UK-Dublin feeders and transatlantic connections where the final-destination delay is the key evidence point.
If the disruption was a missed connection on one booking, measure delay at your final destination. If you self-transferred on separate tickets, UK261 usually treats each flight separately, so the airline may not owe compensation for the onward miss even if travel insurance helps.
Use the free route before paying a claims handler
You do not need a paid claims company to file a Aer Lingus UK261 claim. Build your evidence, file directly with the airline, escalate through the correct ADR or CAA route if needed, and only consider paid help if the case is complex enough to justify losing part of the payout.
