What happened to DL4
Delta Air Lines flight DL4 from London Heathrow Airport to John F Kennedy International Airport on Friday, 23 October 2026 took off at 20:12 instead of 16:20, a delay of 3h 52m. That's 0h 52m past the 3-hour compensation threshold.
The dark line marks 3 hours, the point where compensation starts.
This delay was read from the London departure board. Compensation depends on when the doors open at your destination, which can be slightly earlier or later. We confirm the exact arrival time when you claim.
Are passengers owed compensation?
Yes, most likely. DL4 departed the UK, so it's covered by UK261 whichever airline operated it. The only exception is if Delta Air Lines can prove the disruption was caused by extraordinary circumstances outside its control.
| Passengers | Compensation | You keep after 5% |
|---|---|---|
| 1 passenger | £260 | £247 |
| 2 passengers | £520 | £494 |
| 3 passengers | £780 | £741 |
| 4 passengers | £1,040 | £988 |
What Delta Air Lines might say
Airlines can refuse compensation for "extraordinary circumstances". Some reasons genuinely count, and many that airlines use don't:
Usually still owed
- Technical faults with the aircraft
- Crew shortages or sickness
- The airline's own staff striking
- Knock-on delays from an earlier flight
Can be a valid excuse
- Severe weather
- Air traffic control restrictions or strikes
- Security alerts or airport closures
- Bird strikes, if handled properly
The airline has to prove the cause. We check the reason Delta Air Lines gives and challenge refusals that don't hold up.

Frequently asked questions
Can I claim compensation for DL4 on Friday, 23 October 2026?+
Very likely, yes. DL4 from London to New York was delayed by 3h 52m, which is the kind of disruption UK261 pays compensation for, unless Delta Air Lines can prove it was caused by extraordinary circumstances such as severe weather or an air traffic control restriction.
How much compensation is DL4 worth?+
£260 per passenger under UK261, based on a flight distance of about 5,540km. Every passenger on the booking can claim, including children, so a family of four could be owed £1,040.
What if Delta Air Lines says it was extraordinary circumstances?+
Airlines often say this, but technical faults, staff shortages, crew sickness, the airline's own staff striking and knock-on delays from earlier flights do not count. The airline has to prove the cause. We check the reason given and challenge refusals that don't hold up.
How long do I have to claim?+
Up to 6 years in England, Wales and Northern Ireland, and 5 years in Scotland. There's no need to rush, but claims are easier while your booking details and messages from the airline are to hand.
Do I need my boarding pass to start?+
No. Your booking reference and the names of the passengers are enough to start. If anything else is needed later, such as a boarding pass or ID, we'll ask.
