This is history, not a promise — your specific flight could well be on time.
Was your Aer Lingus flight delayed 3+ hours?
If you arrived 3+ hours late — or were cancelled at short notice — flying Aer Lingus from the UK, you may be owed up to £520 under UK261 (€600 under EU261). It doesn't depend on what you paid for the ticket — only the flight distance and the cause.
You don't need anyone to do this for you — Aer Lingus pays you directly and you keep 100%:
Confirm you qualify — run the 1-minute checker for your likely amount.
Write to Aer Lingus — email their customer-relations team with your booking reference, flight number, date and how late you arrived, stating you're claiming under UK261 (or EU261).
If they refuse or go quiet — escalate to the UK CAA (or the relevant national body) or a small-claims process.
Rather not chase Aer Lingus yourself? A no-win-no-fee partner does the whole thing and keeps about 35% if it wins — so on a £520 claim you'd keep around £338. Less money, zero hassle. Full guide →

How do I claim compensation from Aer Lingus?
You can claim it yourself for free: email Aer Lingus's customer-relations team citing UK261/EU261, your flight number, date and how late you arrived. If they refuse, escalate to the CAA. Or a no-win-no-fee partner can handle it for roughly 35% of the payout.
