Business travelers or travel managers will be able to book stays directly through Airbnb and travel managers will also be able to track and expense their employees’ bookings, similar to how they already track hotel bookings. That integration lets reservation details for each business trip be automatically shared with travel management companies, allowing travel managers to access that data in real-time through expense reporting platforms and travelers to view their booking details in their corporate itineraries and on their mobile devices, which wasn’t possible before if they booked through Airbnb. This integration will go live in the U.S. this summer and expand to other countries later this year. American Express Global Business Travel isn’t the first travel management company to partner with Airbnb as Concur, for example, began letting business travelers book Airbnb rentals through its TripLink service in July 2014, pre Airbnb for Business.
