What a ground stop means and how to learn about one is active

A ground stop at Denver International Airport (DEN) means the Federal Aviation Administration (FAA) has ordered all flights into or out of the airport to pause temporarily. When this happens, planes already in the air continue to their destination, but no new departures are allowed and arriving flights are held at their origin airport. Ground stops usually last between 30 minutes and a few hours, though severe weather or major operational problems can extend them longer.

To find out whether a ground stop is active right now, check the FAA's official website at faa.gov. The FAA maintains a real-time list of ground stops, airport closures, and delays under its "Delays and Cancellations" page. You can also call Denver International Airport directly at 303-342-2000 and ask the operations desk, or check your airline's website or app — they update their systems when ready when a ground stop takes effect.

Twitter and local Denver news outlets often post ground stop notices within minutes, but the FAA website and your airline are the authoritative sources. Social media reports can be outdated or incorrect, so use them only to prompt you to check the official channels.

Key Takeaways

  • A ground stop halts all departures from Denver International Airport, though planes already airborne land normally.
  • The FAA's official website at faa.gov shows active ground stops in real time and is the most reliable source.
  • Your airline's website or app updates when ready when a ground stop begins and shows how it affects your specific flight.
  • Denver International Airport's operations desk at 303-342-2000 can confirm whether a ground stop is in effect and how long it is expected to last.

Why ground stops happen at Denver

Denver International Airport sits at 5,280 feet elevation on the high plains, which makes it vulnerable to sudden weather changes. Severe thunderstorms, hail, heavy snow, and wind gusts can trigger ground stops within minutes. The airport also experiences occasional ground stops due to runway maintenance, equipment failures, or air traffic control staffing issues.

Summer afternoons bring the highest risk of thunderstorm-related ground stops, particularly from May through September. Winter ground stops are usually tied to heavy snow or icing conditions. Ground stops are rare on clear days unless there is a specific operational problem at the airport or in the surrounding airspace.

What happens to your flight during a ground stop

If you are scheduled to depart Denver during a ground stop, your flight will not leave the gate. The airline will hold you at the airport, and you will remain on the plane or in the terminal depending on how long the stop is expected to last. If the ground stop lasts more than a couple of hours, airlines typically allow passengers to deplane.

If you are flying into Denver and a ground stop is declared, your plane will be held at your departure airport. You will not take off until the FAA lifts the ground stop. The airline will announce the delay and provide updates as the situation changes. Once the ground stop ends, flights resume in the order they were scheduled, so there may be a backlog of departures.

You are not charged extra fees or penalties for delays caused by a ground stop — this is considered an act beyond the airline's control. However, if you miss a connection because of a ground stop, the airline is responsible for rebooking you on the next available flight at no charge.

How long ground stops usually last

Most ground stops at Denver last between 30 minutes and two hours. The FAA lifts a ground stop once the weather clears, the equipment is repaired, or the operational problem is resolved. The FAA does not announce how long a ground stop will last when it begins — conditions change too quickly to predict accurately.

Severe weather ground stops can last longer if thunderstorms keep moving through the area or if snow accumulation is heavy. In rare cases, a ground stop might last four to six hours or longer. The FAA updates its website and notifies airlines every 15 to 30 minutes, so check back frequently if you are waiting for a ground stop to end.

Tracking your specific flight during a ground stop

Your airline's website or mobile app is the fastest way to see how a ground stop affects your flight. Most airlines display a message like "Delayed due to ground stop" or "Awaiting departure clearance" and update the estimated departure time as conditions change. You can also text or call your airline's customer service line — the number is on your confirmation email or ticket.

Flight tracking websites like FlightAware and FlightRadar24 show real-time flight status and can alert you to changes. These sites pull data from the FAA and airlines, so they update within seconds of a ground stop being declared or lifted. Setting up a notification on your airline's app ensures you get alerts directly from the source.

What to do if you are stuck at the airport

If a ground stop keeps you at Denver International Airport for more than a few hours, you have a few options. You can remain in the terminal and wait for the ground stop to lift. You can ask the airline to rebook you on a later flight that day or the next day. You can also ask for a refund if you decide not to travel.

If the ground stop lasts long enough that you will miss a connection, tell an airline representative when ready. They can rebook you on the next available flight to your final destination at no charge. Keep your boarding pass and any receipts for meals or other expenses — some airlines reimburse passengers for reasonable costs during long delays, though policies vary.

Denver International Airport has restaurants, shops, and charging stations throughout the terminal. If you need to stay overnight, the airport website lists nearby hotels, and some offer shuttle service from the terminal.

Ground stops versus other types of delays

A ground stop is different from a regular delay. A delay means your flight is running late but will still depart; a ground stop means no flights depart at all until the FAA lifts it. A ground delay program (GDP) is another tool the FAA uses — it spaces out departures to manage traffic flow, so your flight may depart 30 minutes to several hours later than scheduled, but you will eventually leave.

Weather delays affect individual flights or airlines based on their routes, while ground stops affect all traffic at the airport. A runway closure affects only flights using that runway. Understanding which type of delay you are facing helps you estimate how long you will be stuck and what your options are.

Frequently Asked Questions

Can I get a refund if a ground stop cancels my flight?

If the airline cancels your flight due to a ground stop, you have the right to a refund or a rebooking on another flight. The airline cannot charge you a change fee. However, ground stops rarely cancel flights outright — they delay them. If your flight is rebooked to the next day or later, you can ask for a refund instead.

Will I be charged extra if I miss a connection because of a ground stop?

No. If a ground stop causes you to miss a connection, the airline must rebook you on the next available flight to your final destination at no charge. This is considered a delay beyond the airline's control, so you are not responsible for any fees.

How often do ground stops happen at Denver?

Ground stops at Denver are not common. They occur most often during severe thunderstorms in summer and heavy snow in winter. You might experience one every few years if you fly regularly from Denver, but many passengers never encounter one.

Can I check for ground stops before I leave for the airport?

Yes. Check the FAA website at faa.gov or your airline's app before you head to the airport. If a ground stop is active, your flight status will show a delay. You can also call the airport or your airline to confirm. Checking ahead saves you a trip to the airport if your flight is significantly delayed.

What should I do if the FAA website is not loading?

Call Denver International Airport at 303-342-2000 or your airline's customer service line. Both can tell you whether a ground stop is active and how long it is expected to last. Your airline's app or website usually works even when other sites are slow.
