Say, I have two itineraries booked with Ryan Air. City A to City B, and City B to City C, with a few hours connection in City B. Being a point-to-point airline, Ryan Air does not offer connecting flights, and my itineraries have been booked independently.
Now because of COVID, the second flight City B to City C was cancelled. I was offered a full refund, which I have no hopes of receiving any time soon, but that's a different discussion. The cancellation notice was sent well in advance, so that no recourse to 261/2004 for compensation is possible.
However, with the cancellation of the second flight, the trip as such does not exist any more, and the first flight cannot be used. As per Article 10.2 of Ryan Air General terms & conditions of carriage,
Except as otherwise provided by the Convention or Regulation (EC) No. 261/2004 (click here for the text setting out these rights), if we cancel a flight, fail to operate a flight reasonably according to schedule or cease to operate a route, we shall make a refund to you in respect of each sector shown in the Confirmation/Itinerary which has not been utilised for any of these reasons. The amount of refund shall be equal to the fare paid plus any associated taxes, fees and charges paid.
My itinerary for the flight City A - City B was not utilized because of the cancellation of the flight City B - City C. This is a consequence of Ryan Air's action, which they should care responsibility for. The online customer service agent denies any possibility of refund, and copies and pastes random passages from the agreement.
Question: Can I claim a refund for the unused flight City A to City B, based on the cancellation of the flight City B to City C? If yes, what would be the best ways to do so?
