For some time, bookers have been offered OTA inventory and rates, alongside the hotels’ contracted corporate rate. Driving this trend is the fact that business travelers increasingly behave more like leisure travelers and are booking an airline or hotel supplier of their choice – simply because they can.

In fact, a study from American Express Global Business Travel and GfK finds that as many as 40% of US business travelers book outside of policy. This is not good news for hotels that still agree to static net rates, because as wholesale rates start to appear on the CBTs, these hotels will find their negotiated direct corporate rates undercut yet again.
