City Pair Program (CPP)

The OMB-designated Best-in-Class City Pair Program procures and manages discounted air passenger transportation services for federal government travelers. At its inception in 1980 this service covered only 11 markets, and now covers over 14,000 markets. Today, CPP offers four different contract fares. Please go to Government airfare types to learn more.

Instructions for the FY24 & FY25 CSV files

All fares are listed one-way and are valid in either direction. In the CSV file, Origin and Destination are in alphabetical order regardless of travel direction. The Origin is the airport code (domestic travel) or city code (international travel) that comes first alphabetically and the Destination is the airport or city code that comes second alphabetically.

For example, you are traveling from Washington, DC to London, England. You know the city codes are WAS and LON respectively. The city code LON comes first alphabetically and WAS comes second alphabetically. To find the contract fares, you filter:

Column letter Column name Airport/City Code selection
C ORIGIN_AIRPORT_ABBREV LON

Traveler reimbursement is based on the location of the work activities and not the accommodations, unless lodging is not available at the work activity, then the agency may authorize the rate where lodging is obtained.

Unless otherwise specified, the per diem locality is defined as "all locations within, or entirely surrounded by, the corporate limits of the key city, including independent entities located within those boundaries."

Per diem localities with county definitions shall include"all locations within, or entirely surrounded by, the corporate limits of the key city as well as the boundaries of the listed counties, including independent entities located within the boundaries of the key city and the listed counties (unless otherwise listed separately)."

When a military installation or Government - related facility(whether or not specifically named) is located partially within more than one city or county boundary, the applicable per diem rate for the entire installation or facility is the higher of the rates which apply to the cities and / or counties, even though part(s) of such activities may be located outside the defined per diem locality.
