No US rule pays Delta passengers cash for a delay. What US law gives is an automatic refund when a flight is cancelled or significantly changed, 200 % of your fare up to $1,075 or 400 % up to $2,150 for involuntary bumping, and a $4,700 floor on domestic baggage liability. Leaving an EU or UK airport, EU261 or UK261 applies instead and pays a fixed €250–€600.
Which rules apply to your Delta flight
| The disrupted flight | What applies |
|---|---|
| Departs an EU or EEA airport, or a UK airport | EU261 on an EU/EEA departure, UK261 on a UK departure — a fixed sum by distance band whoever operates the flight (Article 3(1)(a)). US refund and bumping rules still apply to the ticket. |
| Departs a US airport — or any airport outside the EU, EEA and UK | No EU261 or UK261. Article 3(1)(b) reaches an arriving flight only if a Community carrier (or, for the UK, a UK or Community carrier) operates it, and Delta is licensed in the United States. US DOT rules, plus the Montreal Convention on an international itinerary. |
That asymmetry matters more than anything else on this page. An Amsterdam–Atlanta Delta flight that lands more than three hours late is a €600 claim; the identical Atlanta–Amsterdam flight the following week is worth nothing fixed in either system. Amounts and bands are in the EU261 and UK261 amounts table.
Delta departures from Europe: the top band
Great-circle distance to the final destination on that booking sets the band, and every Delta transatlantic route clears 3,500 km:
| Route | Great-circle | Band |
|---|---|---|
| London Heathrow – New York JFK | 5,540 km | £520 under UK261 |
| Paris CDG – New York JFK | 5,834 km | €600 |
| Paris CDG – Detroit | 6,359 km | €600 |
| Amsterdam – Minneapolis | 6,685 km | €600 |
| Amsterdam – Atlanta | 7,066 km | €600 |
| Amsterdam – Seattle | 7,840 km | €600 |
So a European Delta departure is a €600 or £520 claim, several times what the US rules would have produced on the same disruption.
What Delta itself has committed to
Delta publishes a Customer Service Plan — its own DOT-facing commitments, which are contractual promises rather than statute. Read on 6 September 2026, it says Delta will “provide a meal or meal vouchers, if a cancellation or delay results in waiting 3 or more hours beyond the scheduled departure time”, and “provide complimentary hotel accommodations at Delta-contracted facilities, based on availability, as well as complimentary ground transportation to and from the hotel, if you are inconvenienced overnight while away from your home or destination”.
The same page sets out refund timing that matches the federal rule: credit-card refunds “typically within 7 business days of Delta’s initial receipt of the refund request”, cash and cheque “typically within 20 days”. And it sets Delta’s own correspondence clock: it will acknowledge a written complaint “within 30 days of their receipt” and send “a substantive response within 60 days of receiving the complaint”. Diary those two dates when you send your letter.
Delta also appears on AviationADR’s member list, which for a UK flight means a CAA-approved scheme whose decision binds the airline — apply within 12 months of Delta’s final response. DOT publishes an airline customer service dashboard recording which carriers have committed to which amenities for delays and cancellations within their control; we could not open it on 6 September 2026, so check your carrier’s row there yourself rather than take a summary from anyone.
The US rights, in one screen
The full detail is in US passenger rights; the short version for a Delta ticket:
- Refunds (14 CFR part 260). A cancellation, or a change of 3 hours or more domestic and 6 hours or more international, entitles you to a refund of the fare, taxes and ancillary fees if you decline the alternative. “Prompt” is defined in 14 CFR 260.2 as 7 business days for a credit-card purchase and 20 calendar days for other payment; 14 CFR 260.10 requires the original form of payment and forbids a processing fee. Use the US DOT refund letter.
- Bumping (14 CFR 250.5). Involuntary denied boarding pays 200 % of the one-way fare capped at $1,075 for a 1–2 hour domestic or 1–4 hour international arrival delay, and 400 % capped at $2,150 beyond that. A volunteer who accepts a gate offer gets whatever was agreed and nothing more. Use the denied boarding letter.
- Bags. 14 CFR 254.4 stops a carrier limiting domestic liability below $4,700 per passenger — a liability floor you still have to prove against. International bags fall under the Montreal Convention instead.
- Tarmac delays (14 CFR 259.4). You must be allowed to leave the aircraft before three hours domestic or four international, with food and water no later than two hours. No money attaches to a breach.
A voucher is not the refund. Both systems pay money: 14 CFR 260.10 requires the original form of payment, and Article 7(3) of EU261 pays cash or bank transfer unless you sign for a voucher. Accepting airline credit at the desk can end the claim you have not made yet.
Is Delta ever covered by EU261 flying into Europe?
No. Article 3(1)(b) covers an inbound flight from a third country only where the operating carrier is a Community carrier, defined in Article 2(c) as one licensed by a member state. A US-licensed Delta flight into the EU is outside the Regulation, and the UK retained version reaches only “a Community carrier or a UK air carrier” on arrivals.
What if Delta refuses the claim?
For a flight departing the US, file with DOT’s Office of Aviation Consumer Protection at transportation.gov/airconsumer/file-consumer-complaint. DOT does not order compensation for a delay, but it enforces the refund, bumping and baggage rules and its complaint record is what moves an airline. For an EU or UK departure the route is the enforcement body of that country, or the ADR scheme — see where to complain.
The one enforcement pause you should know about
DOT is not enforcing the refund requirements in 14 CFR 260.6, 260.9 and 399.80(l) where a flight is simply renumbered and you are rebooked on the new number with no significant change or delay. The pause began on 5 December 2025 and was extended on 7 July 2026 for one further year while DOT reconsiders what counts as a cancelled flight. The core rule — cancellations, significant changes, delayed bags, services you paid for and did not get — is unaffected.
Rules in force today
This is the law that applies to a flight you take today. A revision of Regulation 261/2004 was adopted in July 2026 — the Parliament approved the conciliation text on 7 July 2026 and the Council gave final approval on 13 July 2026 — and it is not yet in force: it applies 12 months after it enters into force following publication in the Official Journal, and the final text sets the details.
