Europe has strong airline consumer protection rules, at least in theory. In practice even when an airline owes you money for a delay, it’s tough to collect. We’ve seen customers literally send bailiffs to airline offices to collect and airlines even cancel flights to avoid having their aircraft impounded over $300.
Now they may even eliminate the protections in EU regulation 261 (2004) which requires airlines to compensate passengers between €250 and €600 cash for flight delays of over 3 hours, for cancellations, and for involuntary denied boardings due to overbooking.
