• UK CAA: Mirrors EU 261 post-Brexit, with 6-year claim window.

Your Passenger Rights: US DOT, EU 261, UK CAA & ICAO Explained (2026 Update)

Know your rights to strengthen claims. US DOT requires refunds within 7-20 days for cancellations (Federal Register, 2025), with on-time data reporting under 14 CFR part 234. EU 261 covers flights departing EU/UK or arriving on EU/UK carriers: compensation scales by distance/delays (e.g., >3hrs for long-haul). UK CAA enforces similarly, with stats showing higher payouts vs. US (MyFlyright, Claimflights). ICAO/Montreal Convention caps at 1288 SDRs (~€1,500).
