I have been involved with corporate self-booking tools since their inception in the early 1990s. At that time companies such as TravelNet and TTG (now TRX) pioneered a new concept allowing business travelers to book online, but restraining their activity through policy enforcement. Now in 2007 where corporate booking tools have become a mainstream part of a good travel management program, innovation has stalled resulting in a common look and feel across vendors. Many of the corporate tools have embraced the familiar consumer matrix approach pioneered by Orbitz (and quickly copied by Expedia and Travelocity), but other emerging trends are slow to come to the marekt. This is in contrast to new consumer oriented Travel 2.0 companies such as Kayak, Farecast and Farecompare are who are blazing new territory incorporating tools such AJAX and mash-ups to change the stale booking flow common on the big OTAs, but what about the corporate market? Where is the next innovation in corporate tools? My belief is that innovation has already begun and lies in the underlying platform rather than the UI. Yes corporate tools should embrace drag and drop capabilities enabled by AJAX, but at the end of the day you still need to enter your dates, select your flights, hotel and car. How these tools integrate disparate sources and user generated reviews and content will be a space to watch in 2007.
