Sharing-economy startups like Airbnb and Uber are challenging traditional travel vendors – and in the process, they’re forcing many businesses to reevaluate travel policies and conventions that are pillars of the current system. The corporate travel ecosystem is traditionally powered by relationships between travel managers and travel providers, the latter of which includes travel-management companies, airlines, hotel chains and rental car companies. Travel managers and providers negotiate rates and perks based on the volume of travel that a company will book. For example, a multinational company that commits to one airline can often secure a flat discount, free upgrades, free baggage check and last-minute rates that are as much as 75 percent lower than what a leisure traveler would pay.
