This question relates to the definition of flight cancellation, following the following statement on the European Union's official information page for air passenger rights:
Cancellation occurs when:
- your original flight schedule is abandoned and you are transferred to another scheduled flight
- the aircraft took off but, was forced to return to the airport of departure and you were transferred to another flight
- your flight arrives at an airport which is not the final destination indicated on your ticket, unless:
- You accepted re-routing (under comparable transport conditions at the earliest opportunity) to the airport of your original final destination or to any other destination agreed by you. In this case it is considered as a delay and not a cancellation.
- The airport of arrival and the airport of the original final destination serve the same town, city or region. In this case it is considered as a delay and not a cancellation.
Furthermore, it is stated that:
If your flight is cancelled you have the right to choose between reimbursement, re-routing or return.
I am wondering whether AUH and DWC are generally considered to be serving the same region, and if a passenger whose flight destination was changed from DWC to AUH has the right to reimbursement.
My guess would be that AUH and DWC are serving seperate regions, as the United Arab Emirates are an agglomerate of different regions, each having their own laws which generally go further in differences among each other, than differences in laws between provinces in other countries (for example, between Bundesländern in Germany). AUH and DWC are in different emirates.
