Thank you for the question.
The way to simplify the regulations, first and foremost, is to harmonize with the European Union's classification approach for entitlement to compensation. Under the European system, there are only two categories. The first is flight disruptions, which are caused by events that are normal to an airline's operation. That would include maintenance issues. The second is extraordinary circumstances, which would involve events like sabotage and acts of terrorism, or a situation when a whole fleet of a particular aircraft model is being grounded around the world because of some manufacturing defect.
What that allows is.... Even if one may argue that it is, perhaps, harsh with the airlines on its face, it results in a system that is very simple and, therefore, saves money for the public overall. This is because in that type of system, determining entitlement to compensation takes very few numbers and bits of information, such as the flight's supposed arrival time, when the passengers actually arrived and whether there was an extraordinary circumstance. That's it.
