What you're owed

Leaving Heathrow

£520each under UK law

Leaving Washington (Dulles)

£520each under UK law

Washington (Dulles) is outside the UK and EU, so coming back this only applies if a UK or EU airline operated the flight.

Either figure is payable only when the delay was within the airline's control. A technical fault, a crew shortage or a late inbound aircraft all count; genuinely extraordinary circumstances such as severe weather or an air traffic control restriction do not.

Heathrow and Washington (Dulles) are 5,902 km apart (Over 3,500 km), and that distance is all that decides the amount. Which figure applies depends only on which end of the route you departed from, not which way you were travelling.

How many were on the booking

£520 each. £2,080 for a family of four.

£520 just you
£1,040 two of you
£2,080 a family of four

Everyone with their own seat is paid, children included.

What it pays

Every way a Heathrow to Washington (Dulles) flight can pay you

Find the line that matches what happened to you. Past 4 hours the amount stops changing, because it is the distance that sets the price, not the wait.

What you get What happened
£520each You landed 4 hours or more late Counted from when the doors opened at Washington (Dulles), not from when you left Heathrow. About 51 flights a year on this route land 3 hours or more late.
£260each You landed between 3 and 4 hours late On a flight this far the first hour past 3 pays half. Past 4 hours it is the full amount.
£520each plus your money back or a new flight Cancelled, and they told you less than 2 weeks before Count the days from when they told you to the day you were meant to fly. Found out at the airport? That counts. If they put you on another flight, this is still owed unless that flight left and landed close to your original times. About 97 flights a year on this route are cancelled.
£520each £260 if they get you there quickly They bumped you off a full flight This one is owed the moment it happens, before you fly, and the airline cannot make you take a voucher instead. It halves to £260 if the flight they put you on gets you there within 4 hours of your original arrival time.
£520each sometimes more You missed your next flight and got in 3 hours late Judged on when you reached your final stop, not on this leg. One ticket for the whole trip means the money is worked out on the whole trip, so a longer leg can pay more.
£520each You were flying home from Washington (Dulles) Washington (Dulles) is outside the UK and EU, so coming back only counts if a UK or EU airline operated the flight.
Your ticket money back They cancelled and you did not travel at all Paid in money within a week, not vouchers, and you get it whatever notice they gave you.
Food and drinks You waited 4 hours or more at the airport On a flight this far it starts at 4 hours, whatever caused the delay. Keep the receipts.
A hotel and a taxi You were stuck overnight The airline pays for the room and for getting to it. Keep the receipts.
Nothing A big storm or an air traffic hold stopped the flight Airlines blame the weather a lot and are often wrong, so it is still worth putting the flight in.

How close the replacement flight has to be before a cancellation stops paying.

Every flight on this route we logged running 3 or more hours late, or cancelled, since August. Each row shows the direction it actually flew, and only flights UK or EU rules cover are listed, so you may see far more of one heading than the other.
