It's not of about the cryptocurrency and exchanges. Instead, It's about how it is related (use case) as part of the current issues you face in your life as a traveler.

Ethereum Travel Application changes the way the users transact to make a reservation, with the underlying transaction model shifting away from a centralized structure (Online Travel Agents, Sabre, GDS) towards a decentralized system. Third- party intermediaries like OTAs (Online Travel Agencies) and GDS (Global Distributed Systems), whose services are needed today in most travel industries, are no longer required in such systems – at least according to the blockchain theory – given that transactions can be initiated and carried out directly “from peer to peer”. This can cut costs for both the end users/ travel industries and speed up processes. As a result, the entire system becomes more flexible, as many previously manual work tasks are now carried out automatically through smart contracts.
