UPDATE - in related Travelport news here is an interview with Graham Nichols (Worldspan vice president and general manager EMEA) on the merger between Worldspan and Galileo. The questions I most want to ask is "What is the future of the Worldspan brand?". Here is Graham's answer (or non-answer as the case may be)
Should the merger proceed as expected, Worldspan will become a Travelport company and will operate under its own brand, similar to how Galileo currently operates. Until we are merged we will operate as two separate companies.
