German airline Hahn Air, which offers scheduled and charter flights within Europe, announced on Monday it has issued the first airline tickets enabled by blockchain technology, in partnership with Winding Tree, an open-source travel distribution platform.

“While blockchain technology is currently almost exclusively associated with the cryptocurrency bitcoin it bears great potential for all industries and endless applications. It will have an enormous impact on all areas of economy and commerce over the next decades,” said Maksim Izmaylov, Founder of Winding Tree.

Using the Winding Tree platform, Hahn Air is able to list inventory, manage the reservation requests, and receive payments once the booking process is complete. As a mode of payment, the airline accepts cash, credit card, or cryptocurrency, either the lif token or ether.

Winding Tree is a blockchain-based, decentralized, open-source travel distribution platform. It has established partnerships with airlines and service companies such as Air Canada, Air France-KLM, Hahn Air, Lufthansa, and Swissport.
