Flight tickets distribution today is built on systems from 30 years ago. In addition approx. 1 billion $ are frozen in guarantees to the airlines as the ticket &payment settlement is asynchronous.
In 2015, IATA introduced the new distribution capabilities (NDC), which revolutionize the current system and how airlines, travel agencies & customers interact. This mediator is the FLYLA global airline distribution system (GADS) powered by a proprietary billing and settlement blockchain.
