LAX to LHR Flight
Delayed or Canceled?
Los Angeles to London is a premium long-haul route. A disruption is expensive - in time, money, and missed plans. Two regulatory frameworks protect you. Here is how to use both.

Route overview
Your rights on LAX-LHR flights
US DOT rules apply to the LAX departure. UK261 applies to the LHR departure on the return. Both protect you.
UK261 applies on the LHR return departure
UK261 applies to all carriers departing from UK airports, regardless of airline nationality or passenger nationality. Your LHR-LAX return delayed by 3 or more hours entitles you to up to £520 per person in fixed compensation.
US DOT refund (outbound)
100%
Full cash refund to your original payment method if your LAX-LHR outbound is canceled or significantly delayed and you choose not to travel. Applies regardless of ticket type.
UK261 fixed compensation (return)
£520
Fixed compensation of up to £520 per person for a delay of 3 or more hours at your final destination on the LHR departure. Applies to all carriers.
Duty of care (return)
During delays of 2 or more hours departing LHR, the airline must provide meals and refreshments. For overnight delays, hotel accommodation and transport to and from the hotel are required.
Why LAX-LHR flights get delayed
- 1.A 10.5-hour flight leaves little margin for recovery - a 1-hour departure delay at LAX often becomes a 2-3 hour arrival delay at LHR.
- 2.LHR's extreme slot constraints mean a missed landing slot from a late arrival adds significant hold time.
- 3.LAX airspace congestion delays westbound inbound rotations, causing the eastbound LAX-LHR aircraft to depart late.
- 4.North Atlantic weather and jet stream routing decisions affect fuel burn and arrival times on this ultra-long-haul.
- 5.Aircraft maintenance requirements for long-haul widebody fleets cause more frequent mechanical delays on these routes.
Weather delays do not eliminate your right to a refund if you choose not to travel.

How to claim compensation for a LAX-LHR disruption
Check your eligibility
Your LAX-LHR outbound is covered by US DOT rules. If your LHR-LAX return was disrupted, UK261 applies and you may be owed up to £520 per person. Check both legs.
Gather your documents
You need your booking confirmation or e-ticket number, the flight number and date, receipts for any out-of-pocket expenses incurred during the disruption, and your boarding pass if available.
File claims for each applicable leg
File your US DOT refund claim for the outbound leg directly with the airline. For the return LHR-LAX leg, file a separate UK261 claim citing the regulation by name and stating the exact compensation amount (£220 / £350 / £520).
Escalate if denied
For US DOT claims, escalate to transportation.gov/airconsumer if the airline ignores or denies you. For UK261 claims, escalate to the UK Civil Aviation Authority. Both routes are free for passengers.
