Ground Stop vs Ground Delay Program: What They Mean for Your Flight and Your Rights

A Ground Stop (GS) is an FAA initiative that stops all departures to a specific destination airport for a defined period. The FAA's Air Traffic Control System Command Center (ATCSCC) issues Ground Stops when a destination airport temporarily cannot accept additional arriving aircraft, due to factors like weather, equipment outages, or runway closures.

Typical duration: Ground Stops are usually short, often 30 minutes to 2 hours, and may be extended or lifted as conditions change. Your airline will hold your aircraft at the gate or on the taxiway until the stop is lifted.

Ground Stops are among the most common causes of departure delays in the US, particularly at major hub airports during afternoon thunderstorm seasons. For context on your rights during any delay, see the US passenger rights guide.

A Ground Delay Program (GDP) is a more structured FAA initiative that manages the flow of arriving aircraft at a congested airport by delaying departures at origin airports. Instead of simply stopping all departures, a GDP assigns each airline specific departure windows to meter the arrival rate at the destination.

GDPs are typically issued when arrival demand at an airport will exceed its acceptance rate for an extended period, often several hours. GDPs affect hundreds of flights across many origin airports simultaneously.

• ›

  GDPs are usually caused by weather at the destination airport (fog, thunderstorms, low visibility)

• ›

  Each airline receives a Controlled Time of Departure (CTD) for each affected flight

• ›

  Passengers may wait at the gate for hours before departure

• ›

  Connecting passengers are at high risk of missing their connections

Key distinctions between the two programs:

• ›

  Scope: Ground Stops affect all departures to a specific airport; GDPs are more surgical, assigning departure slots by airline and flight

• ›

  Duration: Ground Stops are typically shorter and more reactive; GDPs can run for many hours and are more planned

• ›

  Impact: A Ground Stop may mean a 1-2 hour delay; a GDP can mean 3-5 hour delays or more

• ›

  Passenger visibility: Ground Stops are often displayed as 'FAA weather delay' on departure boards; GDPs appear as various delay codes

For US flights, neither Ground Stops nor Ground Delay Programs automatically trigger a compensation requirement. Unlike EU261, which requires payment for delays over 3 hours, US DOT rules do not mandate compensation for delays (only for involuntary bumping and flight cancellations/significant changes).

Important distinction: You may be owed a refund if the airline cancels or significantly changes your flight, but simply being delayed on the ground during a GS or GDP does not trigger mandatory cash compensation under US law.

FAA traffic management delays are generally considered outside the airline's control, which also means airlines can deny EU261 compensation for European flights affected by legitimate FAA programs. However, airlines still have customer service commitments under their own policies.

Even without mandatory compensation, you have rights during ground program delays:

• ›

  The right to deplane if you have been held on the tarmac for 3 hours (domestic) or 4 hours (international) without departing, under the DOT tarmac delay rule

• ›

  The right to accurate information about the cause and expected duration of the delay

• ›

  The right to a refund if the airline ultimately cancels the flight rather than completing the delayed departure

• ›

  Access to food and water after 2 hours of tarmac delay

If the delay causes you to miss a connection and the airline rebooks you on a flight that arrives significantly later than scheduled, the rebooking may constitute a significant change triggering DOT refund rights.

For European flights, FAA Ground Stops and GDPs affecting US-origin flights could be used by airlines as an extraordinary circumstances defense against EU261 claims. However, the circumstances must genuinely be outside the airline's control and unavoidable.

If your EU-carrier transatlantic flight was delayed because an FAA GDP held your aircraft in New York, the airline has a plausible extraordinary circumstances argument. But if the delay cascade was caused by initial airline scheduling issues that were then compounded by an FAA program, the claim may still have merit.

For EU261 transatlantic route guides, see New York to Dublin EU261 rights and Los Angeles to London Virgin Atlantic UK261 claims.

During a ground program delay:

1. 1

   Save the departure board screenshots showing 'FAA Delay' or 'Weather' as the delay reason

2. 2

   Record your actual departure time and final destination arrival time

3. 3

   If the airline cancels the flight, document the cancellation notice and any rebooking offer

4. 4

   Keep boarding passes and any written or emailed delay notices

5. 5

   If you are held on the tarmac for 3 hours without departing, inform a flight attendant you wish to deplane

If the airline cancels your flight during a prolonged GS or GDP, you may be entitled to a cash refund for a qualifying significant change. See TravelStacks for $19 US DOT claim filing or the US passenger rights guide for all your rights.
