If your flight from Europe is delayed/canceled, your airline [no matter what airline] is required to compensate you!!!!!
The law, EC 261, in effect since 2005, applies to any European Union airline flying to or from a member state. But here’s a detail that American carriers would prefer their customers not know: it applies to all flights departing from the European Union, regardless of the passengers’ nationality.
That means travelers flying on American, Delta, Continental, United and US Airways from Europe to anywhere else in the world are covered by the European Union’s passenger rights laws — a fact that representatives from those airlines (except United) reluctantly confirmed, after multiple phone calls and e-mail messages.
