FAA Abbreviation Reference
Dulles (IAD) Airport Delays — FAQ
What does an active FAA delay mean at IAD?
An active FAA delay at IAD means the FAA has issued an advisory — such as a Ground Stop, Ground Delay Program, or Arrival/Departure Delay — affecting flights operating at Washington Dulles International Airport. It is a system-wide restriction, not specific to one airline.
What is a Ground Delay Program at IAD?
A Ground Delay Program at IAD means inbound flights are being held at their departure airports and given controlled release times. This absorbs delay on the ground rather than in the air, saving fuel and improving safety. GDPs typically last several hours.
What is a Ground Stop at IAD?
A Ground Stop at IAD temporarily halts all departures heading to Dulles. Flights already en route are generally allowed to continue. Ground Stops are usually shorter in duration than Ground Delay Programs and are issued when conditions change rapidly.
How often is IAD FAA delay data updated?
FAA delay status for IAD on FlightStatus.flights refreshes every 5 minutes from official FAA NAS data. The Delay History section above shows all status changes detected in the past 24 hours.
Are FAA airport delays the same as individual flight delays at IAD?
No. FAA airport delays are system-wide advisories issued by the FAA affecting all flights at IAD. Individual flight delays may also be caused by airline-specific issues such as late-arriving aircraft, crew availability, or mechanical problems. Both can occur simultaneously.
