If you’re flying on a codeshare operated by another airline, your passenger rights usually depend on the operating carrier (the airline that actually flies the plane). However, if that airline is EU-based or your flight departs from the EU/UK, you may be entitled to compensation under EC 261 (or UK 261) for eligible delays or cancellations. Let AirHelp check your eligibility and file the claim.
