Of total U.S.-booked air volume, 78 percent went through an approved online booking channel. Seventy-four percent of 2017 U.S.-booked air volume was for international travel. In 2017, the company launched a new air program. Optimizing that program will be a priority for 2018. Additionally, Merck will focus on data and on enabling technologies this year. Merck's single global travel policy underwent two changes in 2017: The number of travelers allowed on a single flight increased from 25 to 40, and the company adjusted the definition of lowest fare to reflect its new air program. Its card program is individual bill/central pay. Amex GBT is the company's consolidated TMC in the U.S., EMEA and Latin America, and BCD Travel supports the company's travel needs in Asia/Pacific.
