The cryptocurrency superintendent announced the move according to instructions from the country's president, Nicolás Maduro. Via Twitter, he revealed it stating that "airlines are allowed to sell tickets on domestic and international flights in «Petro» and other cryptocurrencies."
Earlier this month, Maduro ordered several state-owned businesses to transact in Petro when buying and selling products and services. These businesses include PDVSA, a state-owned oil and natural gas company, as well as the Corporacion Venezolana de Guyana (CVG), a decentralized conglomerate whose subsidiaries include precious metal producers.
According to local news source Telesur, since the Petro was launched on February 20, investors and entrepreneurs from 127 different countries have shown interest in the cryptocurrency. As recently covered by CCN, this meant over 171,000 individuals and companies registered for the pre-sale.
