If it was a Wingly transaction - quite possible but not confirmed, they have the following on their website:
EU safety regulations only permit cost-shared flights by private individuals, if the direct cost (i.e. cost directly incurred in relation to the flight, e.g. fuel, airfield charges, rental fee for an aircraft) are shared between all parties, including the pilot. Cost-shared flights shall not have an element of profit. If a flight is not a cost-shared flight in accordance with EU safety regulations, the flight will be qualified as a commercial flight and commercial air operation rules will apply.
The cost-shared flight will be conducted under the sole responsibility of the pilot under the applicable regulation for non-commercial flights with light aircraft by private pilots. It is also the pilot’s responsibility to ensure the flight is insured for flights with passengers. See the Insurance page: https://en.wingly.io/index.php?page=...page=insurance
Bad weather conditions are a primary reason for accidents in non-commercial General Aviation flights with light aircraft. Weather conditions can change quickly, as a result the pilot may cancel the flight. Therefore, the day before the actual flight, the pilot should inform the passenger of the weather forecast regarding the feasibility of the flight. The presence of the passenger on the day of the flight and their expectations that it will take place, shall not make the pilot reluctant to cancel a flight.
