Delta Air Lines arrives late
20%of the time on its UK routes (15+ min late).
This is history, not a promise — your specific flight could well be on time.
Was your Delta Air Lines flight delayed 3+ hours?
If you arrived 3+ hours late — or were cancelled at short notice — flying Delta Air Lines 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 — Delta Air Lines pays you directly and you keep 100%:
Confirm you qualify — run the 1-minute checker for your likely amount.
Write to Delta Air Lines — 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 Delta Air Lines 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 →
