An airport delay program is an FAA traffic-management program that meters arriving flights when demand exceeds capacity at an airport.

What this signal means

Delay programs help manage congestion, weather impacts, runway constraints, and traffic flow without treating every flight the same.

Remember
Delay programs manage arrival rate; airlines still make flight-level decisions.

How arrival metering works

When arrival demand exceeds safe airport capacity, an ADP spreads delays across inbound flights instead of letting airborne holding build up. Flights may receive controlled departure times from origin airports.

The headline average delay is a network measure; an individual flight can be better or worse depending on route, aircraft rotation, and airline recovery choices.
