There are two regulations in force to assess how much and how passengers will be compensated by airlines. This will depend on the territory from which the flight took off/landed:
- Regulation 261/2004 of the European Union.
For flights that are operated by European companies, regardless of the place of departure or destination. Or for flights departing from a European airport.
- The Montreal Convention.
For flights operated by non-European companies and departing from somewhere outside the European Union.
The vast majority of flight claims are subject to EU regulations. Most claims for flight delays and cancellations are focused on low-cost airlines. And these are the destinations most frequented.
