The company's in-house Boeing Travel Corporate Travel Department continued to handle all global travel services with some support provided by Australia-based TMC Corporate Travel Management, but the aerospace giant added integrated additional subsidiaries for travel, expense and credit card services during the year. A new policy required employees to use preferred parking facilities for airport parking when available, while the company's employee handbook now also applies to extended business trips of 30-89 days. Boeing saw U.S.-booked air volume drop by 12.3 percent in 2019 from 2018's $244 million. Ninety-three percent of the company's U.S.-booked tickets went through approved online tools in 2019—a 1 percent compliance uptick from 2018—and 81 percent of those bookings required no agent help. Eighty-two percent of its U.S.-booked air travel was for domestic travel in 2019, up from 78 percent in the previous year. The company's goals for 2020 include improving end-to-end expense reporting and compliance, integrating immigration and tax assessment into pre-trip approval processes and implementing an enterprise meetings and events policy.
