3.5 Carrier undertakes to use its best efforts to carry the Passenger and Baggage with reasonable dispatch. If due to circumstances beyond its control Carrier cancels or delays the flight, is unable to provide previously confirmed space, fails to stop at the Passenger's stopover or destination point, or causes the Passenger to miss a connecting flight on which the Passenger holds a reservation, Carrier shall either:
3.5.1 carry the Passenger on another of its scheduled passenger services on which space is available; or
3.5.2 re-route the Passenger to the destination indicated on the Ticket or applicable portion thereof by its own scheduled services or the scheduled services of another Carrier, or by means of surface transportation. If the sum of the fare, excess baggage charge and any applicable service charge for the revised routing is higher than the refund value of the Ticket or applicable portion thereof, Carrier shall require no additional fare or charge from the Passenger, and shall refund the difference if the fare and charges of the revised routing are lower; or
3.5.3 make a refund in accordance with the provisions of the Fare Rules (available on Aegean's website) and applicable law and shall be under no further liability to the Passenger.
