Expedia, the travel resource to plan a trip from beginning to end, features an Android SDK. The project contains 2 components: An Android optimized Java library to make calls to the Expedia Affiliate Network API and a sample Android app that uses the API to visualize the example of the calls made. The requirements to create applications with travel features include Java JDK 1.6+ and Apache Ant 1.7+. The Expedia Android SDK needs to have the tools and the platform directories on the path, and supports Android version Ice Cream Sandwich 4.0 and above. If users are have additional interest about development possibilities such as how to build a fully API dependent site, style content to a particular business model, or control brand with SEO/SEM benefits, then they can use the Expedia EAN API. With the EAN API, users can register for an API key and launch a site.
Airbnb's CEO, Brian Chesky, hinted that Airbnb may soon open an API for third party integration. Chesky envisions the company shifting from a marketplace to a travel platform upon which third parties can plug into. While no specifics were given, Chesky suggested that lack of an API is a hole.
In 2011, we learned that even our cars and trucks were going "social" when Salesforce.com announced its partnership with Toyota. However, the social capabilities of the partnership were limited in scope (car diagnostics, tune up reminders, etc.). What if your car could prevent you from driving a certain route because it knew what areas were traffic-heavy? That car sounds "social" in a fuller sense; it might be possible with the new Beat the Traffic API.
There is no doubt that there is a lot of money to be made in travel. Heck, travel (globally) accounts for over 12% of the World's GDP. That is some serious coin. You have an incredible idea for a web application that is going to make travellers love you and make you rich at the same time. The question is... who should I connect with and why? Here is a quick run down on the pros and cons of connecting with the likely, and not so likely, hotel distribution partners.
