While the attention has been on what the hiring of Expedia CEO Dara Khosrowshahi would mean for Uber, there is also the question of what happens to top spot at the travel giant.

Expedia isn't commenting, but we're hearing that CFO Mark Okerstrom is the logical and likely choice to take over the top spot. Okerstrom joined Expedia in 2006, a year after Khosrowshahi and has been CFO since September 2011. Before joining Expedia he was a consultant for Bain & Co. in San Francisco.
