Currently, we are focusing only on three travel domains (Airlines, Hotels and Car rentals). The scope of this project is to integrate these three domains using federation protocols and provide more flexibility and better user experience to the travelers. Ethereum Travel Tokens will not only solve the payment hassles in the industry, it is armed with the best features of blockchain technology as it guarantees fast and instantaneous transaction, low, frictionless, cross-border transaction, and allowing travelers to control who and when they share their data to, perform transaction on the ETH Travel platform, and select from the increasing pool of travel destinations. Hope this helps!!!

Thanks much for a very good question.
