Delta Air Lines delay compensation, and how often you'll actually need it
£520 per passenger, if your Delta Air Lines flight arrived 3 or more hours late
Every Delta Air Lines route we hold a distance for falls in the same band, so that is the figure. About 76 Delta Air Lines flights a year cross that line.
In the last 12 months, Delta Air Lines operated 8,476 flights at UK airports, and 0.9% were 3 or more hours late, the threshold where £520 per passenger becomes payable.
Punctuality is up on last year: 79.3% of flights ran on time against 76.3% in the twelve months before, and the average delay fell from 15.9 to 13.1 minutes.

How to claim from Delta Air Lines
If Delta Air Lines refuses and you think the refusal is wrong, the next step is Aviation ADR, a free independent scheme whose decision the airline has agreed to accept. You do not need a solicitor and you do not pay to use it.
You can claim directly yourself and keep the whole payout, or a claim firm will do the chasing for a share of it. Both end up at the same place.

What the rules turn on
Where the flight departed decides everything, not the airline's nationality. Anything leaving a UK airport is covered by UK261 whoever operates it, and anything leaving the EU by EU261. A delay of 3 or more hours on arrival pays £220 to £520 per passenger when the cause was within the airline's control, which covers technical faults, crew shortages and the knock-on from a late inbound aircraft. It pays nothing when the cause was genuinely extraordinary, though airlines stretch that word further than the case law supports, so a refusal on those grounds is worth testing rather than accepting.
