Revolutionizing travel with ML & Analytics – An insight into business optimization using Machine Learning and Advanced Analytics

Submitted Jun 15, 2015

At Orbitz, Big Data technologies have helped transform the way we let people travel. In this talk we elaborate on how we at Orbitz have leveraged intelligence derived from more than 2 PB of semi-structured and unstructured data to optimize various facets of our business such as content optimization, search personalization and channel optimization.


Big data technology is at the heart of our business. Our Travel sites generate about 1 TB of data per day which is stored in HDFS. This data is at the heart of machine learning, advanced analytics and visual analytics. We go over a few case studies which have had a great impact on travel experience for our users and the technology behind them.

  1. Usage of machine learning to provide personalized sorting of search results which in turn increased the propensity to buy.
  2. Collecting and analyzing Site experimentation data.
  3. Marketing Channel Optimization and Campaign effectiveness
  4. Data platform that enables all of our use cases
