If your booking only contains flights, then you have to wait until at least one of the flights is cancelled. If all of the flights are operating, then you are out of luck.
If the booking, in addition to the flights, also contains a car, a hotel, a guided tour or something similar, then you could argue that you have the right to cancel for a full refund, citing Chapter III Article 12 Section 2 of
Directive 2015/2302:
Notwithstanding paragraph 1, the traveller shall have the right to terminate the package travel contract before the start of the package without paying any termination fee in the event of unavoidable and extraordinary circumstances occurring at the place of destination or its immediate vicinity and significantly affecting the performance of the package, or which significantly affect the carriage of passengers to the destination. In the event of termination of the package travel contract under this paragraph, the traveller shall be entitled to a full refund of any payments made for the package, but shall not be entitled to additional compensation.
