My flight was cancelled, not delayed.

I read

Article 5 Cancellation

1. In case of cancellation of a flight, the passengers concerned shall:

(c) have the right to compensation by the operating air carrier in accordance with Article 7, unless:

(iii) they are informed of the cancellation less than seven days before the scheduled time of departure and are offered re-routing, allowing them to depart no more than one hour before the scheduled time of departure
and to reach their final destination less than two hours after the scheduled time of arrival.

Article 7 Right to compensation

1. Where reference is made to this Article, passengers shall receive compensation amounting to:

(c) EUR 600 for all flights not falling under (a) or (b).

2. When passengers are offered re-routing to their final destination on an alternative flight pursuant to Article 8, the arrival time of which does not exceed the scheduled arrival time of the flight originally booked

c) by four hours, in respect of all flights not falling under (a) or (b),

the operating air carrier may reduce the compensation provided for in paragraph 1 by 50 %.

So for me the question is, 600 EUR or 50% of 600 EUR.

They can not pay for the new BRU-ZYR ticket, the only thing they can do is reimburse the ticket I have bought myself through customer care. In DXB, the only two options I got for rebooking were DXB AMS or DXB BRU on EK.

I am talking about 4 hours and 22 minutes.
