Headquartered in Sofia, Bulgaria, Colibra develops solutions that boost air travel amid uncertain travel times. The award winning “Fly now. Pay if Okay” travel booking app empowers passengers to book risk-free travel products without bearing financial risk. The flights feature allows users to book air tickets in three easy steps with no upfront payment. Users’ credit cards are charged only if the flight arrives on time. In case of a flight delay of more than 3 hours, the passenger flies for free. In the event of flight cancellation, the passenger does not need to deal with refunds, travel vouchers and claiming flight compensations.
