In 2015, it served 87,000 employees of Boeing and its subsidiaries, and they spent a sliver more on U.S.-booked air volume than in 2014. Of the U.S.-point-of-sale flights, 93 percent are made through Boeing’s approved online tool, and 69 percent of whose were done without agent assistance.In 2015, it brought more international locations and subsidiaries under the CTD. It also upgraded its Concur travel and expense tools and renewed its contract with that supplier and its contract with its global distribution system. It updated its policy to cover monthly inflight Wi-Fi subscriptions and to allow hotel room upgrades given a valid business justification. This year, it aims to reduce the nonrefundable ticket credits that expire, bring more non-U.S. locations under the CTD umbrella, consolidate group/meetings bookings, implement new mid-office tools and reduce travel costs by 25 percent. The company expects U.S.-booked air volume to drop to $292.5 million this year. Boeing is updating travel policy to disallow executives who have corporate cars from expensing mileage on privately owned vehicles. It’s also fixing a booking tool glitch that prevented travelers eligible for first class airfare from voluntarily downgrading to business class; the system previously offered only coach as an alternative. From 2014 to 2015, Hilton and Marriott remained as primary hotel suppliers for Boeing, but InterContinental stepped into Hyatt’s place.
