The Schiphol airport in Amsterdam has published a Flight API for developers to build new, creative passenger experiences. The API provides access to flight and airline data on the more than 90+ airlines that operate at the airport. Examples include flights, airline, status, destinations, and more.
Roomorama is not the only one in the person to person travel accomodations game. The company is in a space that’s been well established by other players: CouchSurfing, Vacation Rentals By Owner and, of course, AirBnB. While there's an AirBNB API planned, the only room rental site that is currently public with its platform is the the Roomorama API.
