Transportation-related services exports minus imports
Millions of current dollars
NOTE: Transportation-related services include passenger fares and freight and port services. It excludes receipts and payments for travel services, which includes purchases of goods and services (e.g. food, lodging, recreation, gifts, entertainment, and any incidental expense on a foreign visit).
These data have not been adjusted for inflation because there is no specific deflator available for transportation-related services. In addition, it is difficult to control for trading partners' inflation rates as well as currency exchange fluctuations when adjusting the value of internationally traded goods and services for inflation.
