You might want to consider talking about Data Service Architectures and Semantic Web Services which are the current buzzwords in the travel industry.
w.r.t. Data services, there’s great momentum in the industry to utilize CRM systems for data mining customers needs, expectations and preferences, and to gain their loyalty for long-term sustainability.
Alternately, you can talk about the effect of Yield Manager type electronic hubs, e.g. priceline that enable consumers to name their own price for an airline ticket or a hotel room etc.
Lastly, the Open Travel Alliance http://www.opentravel.org/ is constantly involved in developing new standards for XML based protocols for interoperability among the parties who’re involved in the Travel Industry supply chain, including carriers, agents and consumers.
You can prolly do a whole project on one of these three ideas, or combine a couple of them for a broader and more cross-functional perspective.
