Air passengers have robust protections under EU261, UK261 (post-Brexit retention of EU261), DOT, and the Montreal Convention. Compensation applies if cancellation isn't due to extraordinary circumstances like weather or external strikes--airline issues (e.g., maintenance) don't qualify.

<1500km €250
1500-3500km €400
>3500km €600 (50% if re-routed timely)
