Los Angeles to London Flight Cancelled: Your UK261 Rights

Los Angeles London flight cancelled UK261 rights apply to the London-to-LAX return leg only. The LAX-to-London outbound is governed by US DOT (refund right) but not by UK261 (UK261 covers UK-departing flights, any carrier). The London-departing return is covered regardless of carrier (British Airways, Virgin Atlantic, American, Delta, United). UK261 mirrors EU261 in structure but pays in GBP and is enforced by the UK Civil Aviation Authority (CAA) rather than EU member state authorities. For a transatlantic cancellation, the cash compensation is GBP 520 per passenger (over 3,500 km), in addition to the ticket refund and Article 9 duty of care.

Outbound LAX-London: US DOT only. Return London-LAX: UK261 applies. GBP 520 per passenger for cancellation or 3+ hour delay.

On codeshares (e.g., American flight number on a British Airways aircraft), the EU/UK261 claim is filed against the operating carrier (BA), not the marketing carrier (American). The operating carrier is the airline that actually flew the aircraft, listed on the boarding pass and ticket as the operator. This distinction is important because the compensation amount, claim process, and enforcement body all attach to the operating carrier. See interline ticket vs codeshare ticket differences and codeshare marketing carrier vs operating carrier: legal definitions.

File against the operating carrier, not the marketing carrier. On a codeshare, the operating airline is the one that actually flew the aircraft.

UK261 (carried over from EU Regulation 261/2004 post-Brexit) Article 9 requires the operating carrier to provide meals and refreshments proportionate to the waiting time, hotel accommodation if the wait extends overnight, and ground transport between airport and hotel. For a London-to-LAX return delayed overnight at LHR, the airline must provide hotel and meals or reimburse you for reasonable costs. The duty applies regardless of cause (extraordinary circumstances do not exempt the duty of care). The CAA is strict on duty of care violations and has issued enforcement notices for systematic non-compliance.

The UK Civil Aviation Authority is the national enforcement body for UK261. If the airline denies a valid UK261 claim or does not respond within a reasonable time (typically 30 days), file a complaint with the CAA. The CAA's complaint form is online and free. The CAA does not adjudicate individual disputes (similar to the US DOT) but does aggregate complaints and issue enforcement actions against carriers with patterns of non-compliance. Filing with the CAA strengthens your individual claim and contributes to systemic enforcement. See EU enforcement body by country: who to email.
