American Express Global Business Travel (GBT) has extended its partnership with Lyft for five years. The partnership, which began in April 2018, fully integrates Lyft’s ridesharing platform, data and insights into more than 100 client travel programs. Clients can use Lyft for ground transportation within a traveler-friendly booking experience, and readily capture spend, making program and savings optimization easier for travel managers. To celebrate the partnership extension, Lyft is providing GBT clients with a promotional rebate on their rideshare spend. Through the program, business travelers have complete access to Lyft for ground transportation, while travel managers can drive cost savings and policy optimization with visibility into spend and data, and flexibility to control program guidelines.  John Bukowski, vice president of global supplier relations for American Express GBT, said the arrangement offers business travelers a travel policy-compliant option for ground transportation that provides “an experience that is familiar to them in their everyday lives.”
