Deloitte in 2025 increased its U.S.-point-of-sale airline volume to $348.7 million, an increase of more than $50 million from the year prior and easily maintaining its position as the second-largest corporate travel program in the United States.
Two benefactors of those increased bookings were Deloitte’s new consolidated U.S. TMC—Blockskye—and new entrant booking tool Kayak for Business. The professional services giant completed its U.S. program migration to the new TMC partner and booking platform last year, and has continued development of key components of the travel program related to cost management, sustainability, traveler accessibility and removing friction from overall business traveler experience.
In 2026, travel program leaders focused on the future deployment of AI solutions, particularly in travel booking pathways and augmenting agent-assisted bookings as well as post-booking servicing. The program is also pursuing additional direct-connect distribution options with suppliers.
