The London–Dublin route is consistently ranked as one of the busiest air routes in the world. With dozens of daily flights connecting Heathrow (LHR), Gatwick (LGW), Stansted (STN), Luton (LTN) and City (LCY) to Dublin Airport (DUB), the approximately 447 km crossing is dominated by Ryanair, Aer Lingus and British Airways.
The sheer volume of flights means delays are common. If your London–Dublin flight arrived late, was cancelled or you were denied boarding, you have a legal right to €250 in fixed compensation under EC 261/2004. This guide tells you exactly how to claim.
Compensation for the London–Dublin Route
At approximately 447 km, London–Dublin is well within the 1,500 km short-haul threshold. The EC 261/2004 fixed compensation is:
€250 per passenger
This is a legal entitlement, not a goodwill gesture. You are entitled to it when:
- Your flight arrived at Dublin or London 3 or more hours late (actual doors-open time), or
- Your flight was cancelled with fewer than 14 days' notice and without an adequate alternative, or
- You were denied boarding against your will due to overbooking or other airline-side reasons.
For two passengers, the total could be €500. For a family of four, €1,000 — all from a short hop across the Irish Sea.
EC 261/2004 — When Does It Apply on London–Dublin?
Ireland is an EU member state; the UK is not (post-Brexit). This creates a nuance specific to this route:
Flights from London to Dublin: Dublin is in the EU. UK airports lost EU status after Brexit, but the UK enacted its own domestic equivalent of EC 261/2004 — the UK AIR2 Retained EU Law. Passengers departing UK airports have equivalent rights under UK law.
Flights from Dublin to London: Dublin is in the EU. EC 261/2004 applies directly for all airlines departing from DUB, regardless of carrier nationality.
Practical impact: Your rights are virtually identical in both directions. The key difference is which enforcement body handles disputes — the UK CAA for departures from UK airports, and the Irish Aviation Authority (IAA) for departures from Dublin.
Eligibility requirements:
- Confirmed booking and on-time check-in
- Actual 3-hour+ arrival delay at destination
- No proven extraordinary circumstances
Main Airlines on London–Dublin — How to Claim
Ryanair
Ryanair operates the London–Dublin route in massive volume from Stansted (STN), Luton (LTN), Gatwick (LGW) and other London-area airports. Despite being legally required to compensate, Ryanair has one of the highest claim rejection rates in Europe. File via Ryanair's EU 261 claims form in the Help Centre. If rejected, escalate to the UK CAA or Irish IAA immediately — Ryanair's rejections are frequently overturned on appeal.
Aer Lingus
Aer Lingus (part of IAG) connects Heathrow, Gatwick and other London airports to Dublin as one of its core routes. Claims are filed through the Aer Lingus Customer Relations portal. Aer Lingus is an Irish carrier and subject to Irish and EU enforcement. Generally more cooperative with valid claims than Ryanair.
British Airways
BA operates London Heathrow to Dublin as part of its domestic/short-haul schedule. File via BA's online Compensation and Refund request system. BA typically processes claims within 4–8 weeks.
Step-by-Step Claim Guide
Step 1: Determine your eligibility Was the actual arrival at destination 3 hours or more after schedule? Was the disruption the airline's responsibility (not genuinely extraordinary)? Check the actual door-open time — airlines sometimes count incorrectly.
Step 2: Document everything Save your booking confirmation, boarding pass (screenshot it before the battery dies), and any delay notification messages. If the airline provided meal vouchers, keep them as evidence of the delay being acknowledged.
Step 3: Submit a formal claim Use the airline's official claims channel. Clearly state: the flight number and date, the scheduled arrival time, the actual arrival time, the number of passengers, and that you are claiming under EC 261/2004. Request €250 per passenger in cash (not vouchers).
Step 4: Chase and escalate If the airline fails to respond within 8 weeks or rejects the claim without justification, file with:
- UK Civil Aviation Authority (CAA) for UK-departure flights
- Irish Aviation Authority (IAA) for Dublin-departure flights
- Or contact AirHelp — they handle Ryanair and Aer Lingus claims professionally and on a no-win, no-fee basis.

FAQ — London to Dublin Flight Delay
Ryanair rejected my claim citing "extraordinary circumstances" for bad weather — what should I do? Request the specific meteorological data and the METAR reports for the day. Bad weather must be directly causative and genuinely unavoidable. Ryanair often cites weather vaguely. The UK CAA or IAA can compel the airline to provide evidence.
My London–Dublin flight was 2 hours and 55 minutes late — can I claim? No. The threshold is exactly 3 hours. A delay of 2:59 at destination does not qualify for the fixed compensation under EC 261/2004.
Can I claim if I flew on a codeshare — e.g. a BA-operated flight with an Aer Lingus code? Your claim is against the operating airline (the one that actually flew the plane), not the marketing carrier. If British Airways operated the aircraft, claim against BA, even if the flight number was Aer Lingus.
How long do I have to file? In the UK, you have 6 years. In Ireland, 6 years as well (contract law limitation). Still, file promptly — evidence may become unavailable over time.
Is the €250 fixed or can the airline reduce it? It is fixed by law and cannot be reduced. Airlines may offer 50% less if they provide a re-routing that meets certain timing criteria under Article 7(2), but for pure delay compensation, €250 is the non-negotiable amount.
