Houston to Heathrow Delay: American Airlines EU261 Claims

Houston Heathrow delay EU261 American Airlines claims apply to the Heathrow-departing return leg only, governed by UK261 (post-Brexit retained EU regulation). The Houston-to-Heathrow outbound is governed by US DOT (refund right) but not by UK261 (UK-departing flights are covered, US-departing are not). American Airlines operates the IAH-LHR route directly and codeshares with British Airways. On codeshares where the operating carrier is BA, the UK261 claim is against BA. On AA-operated flights, the claim is against American. Cash compensation is GBP 520 per passenger for transatlantic distance, in addition to the ticket refund.

Outbound IAH-LHR: US DOT only. Return LHR-IAH: UK261 applies. Operating carrier matters on codeshares.

American's UK261 claims are filed via aa.com under the EU/UK261 claims process (often nested under Customer Relations). Submit the claim with flight details, the cancellation or delay duration, and supporting documentation. American typically takes 4 to 12 weeks for uncontested claims, longer for disputed. American is part of oneworld and shares operational infrastructure with BA at LHR, which sometimes complicates the codeshare attribution. If American disputes the UK261 claim citing the operating carrier was BA, file with BA. If American denies citing extraordinary circumstances, challenge with evidence. See how to get a refund from American Airlines and American Airlines refund policy 2026: what actually applies.

If your AA-marketed flight was operated by BA, file the UK261 claim against BA via britishairways.com. BA has a dedicated EU/UK261 claims team that processes uncontested claims in 4 to 8 weeks. BA's compliance reputation on UK261 is generally good. On disputed claims, BA may invoke extraordinary circumstances, and the standard CJEU-derived counter-arguments apply. See British Airways UK261 claim fees and timelines and British Airways delay compensation EU261.

Heathrow is a major UK261 jurisdiction with significant delay history due to weather (winter fog, summer thunderstorms), ATC restrictions (London TMA congestion), and runway capacity (LHR operates near maximum slot capacity). Delays at LHR are frequent and UK261 cash compensation is paid out at scale. The CAA (UK Civil Aviation Authority) is active in enforcing UK261 against carriers with patterns of non-compliance at LHR. For LHR-specific delay context, see London Heathrow LHR delay EU261 compensation and missed connection at Heathrow EU261 rights.

If both legs of the IAH-LHR round trip are disrupted (separate cancellations on outbound and return), the recoveries are independent: US DOT cash refund for the IAH-LHR outbound (under the 2024 federal rule) and UK261 cash compensation plus refund for the LHR-IAH return. Total recovery on both legs cancelled: USD 800 to USD 1,200 outbound refund plus USD 800 to USD 1,200 return refund plus GBP 520 UK261 cash compensation. Stack all recoveries. See EU261 vs US DOT: which gives more money and can Americans claim EU261 compensation.

Round-trip cancellation: stack US DOT refund (outbound) plus UK261 refund + cash compensation (return). Independent recoveries.
