City Pairs

Measuring the Performance of City Pairs

City pairs refer to the city of origin and a corresponding destination city for flights to and from major metropolitan areas. City pair metrics provide important information to air traffic controllers, airports, and airlines that help them plan schedules and anticipate traffic levels.

Understanding and tracking the time variation for city pair operations can lead to improved traffic flow management and flight scheduling, as well as reduced fuel consumption and aircraft exhaust emissions.

Performance metrics for the city pairs are grouped by metroplex — metropolitan areas with multiple airports and complex air traffic flows. The metrics represent city pairs that operate out of the FAA-designated Core 30 airports, which are based on air traffic operations and passenger boardings.

Included in the city pairs performance metrics are the predictability and efficiency key performance areas, which analyze the annual performance for flights between a city pair operating in the direction indicated.

The Effective Gate-to-Gate Time metric measures the average time between the scheduled gate departure and actual gate arrival at the destination.

The Airborne Time Predictability metric measures the predictability of time elapsed from takeoff to landing for a selected city pair. Determining city pair gate-to-gate performance times can help airlines decide the most efficient way to connect particular markets.
