What is the difference between a ground stop and a ground delay program?

A ground stop halts departures to an airport entirely. A ground delay program meters them — flights receive delayed departure slots, producing average delays the FAA publishes per program.

Q: What is a ground stop at an airport?

A ground stop is an FAA order that halts departures headed to a specific airport — usually for severe weather, equipment outages, or congestion. Flights already airborne continue; flights not yet departed wait at their origin.

What is a ground stop at an airport?

A ground stop is an FAA order that halts departures headed to a specific airport — usually for severe weather, an equipment outage, or congestion. Aircraft already airborne continue; everything else waits at its origin gate. A ground delay program is the milder version: departures are metered with delayed slots instead of stopped, which is why the FAA publishes an average and maximum delay for each program.
