The Travel Price Index (TPI) measures the cost of travel away from home in the United States. It is based on the U.S. Department of Labor price data collected for the monthly Consumer Price Index (CPI). The TPI is released monthly and is directly comparable to the CPI. 

The attached table includes one-month changes on a seasonally-adjusted basis as well as 12 and 24-month changes on a seasonally-unadjusted basis for the TPI and its major components.
