How to learn about O'Hare has a ground stop

A ground stop at O'Hare International Airport (ORD) means the Federal Aviation Administration (FAA) has ordered all flights to stop departing until conditions improve. The fastest way to know if one is in effect right now is to check the FAA's official website at faa.gov/air_traffic/nas/status. The status page shows active ground stops, delays, and weather issues at major airports, updated every few minutes.

You can also call the FAA's Flight Service Station at 1-800-WX-BRIEF (1-800-992-7433) and ask directly about ORD conditions. If you are a passenger with a flight departing or arriving at O'Hare, your airline's website or app will also show ground stop information in real time — most airlines push notifications when a ground stop begins or ends.

Ground stops usually last between 30 minutes and several hours, depending on what caused them. Weather is the most common reason: thunderstorms, heavy snow, or low visibility can trigger a stop. Occasionally a ground stop happens because of air traffic volume, runway closures, or equipment issues at the airport itself.

What happens to your flight during a ground stop

If your flight is scheduled to depart during a ground stop, it will not push back from the gate. Your aircraft will stay at the terminal, and you will remain on board or in the airport, depending on how long the FAA expects the stop to last. The pilot and crew will monitor the FAA's updates and will push back as soon as the stop is lifted.

Arriving flights are sometimes allowed to land during a ground stop, even though departures are frozen. This means planes can come in but cannot leave, which can create congestion at the airport. If you are arriving during a ground stop, your flight may land but then wait on the tarmac or at a gate longer than usual.

Your airline is required to communicate with you about the delay. They will announce the reason and give you an estimated time when the ground stop might end, though that estimate often changes. If the delay stretches beyond a certain length (usually two to three hours for domestic flights), you may be may have access to to meals, hotel rooms, or rebooking on another flight, depending on your airline's policy and whether the delay was within their control.

Difference between a ground stop and a ground delay

A ground delay is different from a ground stop. A ground delay means flights are still departing, but they are leaving later than scheduled — usually 30 minutes to two hours later. During a ground delay, planes take off one at a time with spacing between them, rather than all at once.

A ground stop is a complete halt: no departures at all until the FAA lifts it. Ground stops are rarer and more serious than ground delays. If you see "ground delay" on the FAA status page, your flight will depart, just not on time. If you see "ground stop," nothing is leaving until conditions change.

Why O'Hare gets ground stops more than other airports

O'Hare is one of the busiest airports in the United States, handling more than 2,700 flights per day. Because of that volume, even small disruptions can trigger a ground stop. When weather hits Chicago, the FAA often stops departures to prevent a backlog of planes waiting to take off.

O'Hare's location also matters. Chicago sits in a region where thunderstorms develop quickly in spring and summer, and winter weather can be severe. The airport has four runways, which is fewer than some major hubs, so when one or two runways close due to weather or maintenance, the remaining capacity fills up fast.

How long ground stops usually last

Most ground stops at O'Hare last between 30 minutes and two hours. Weather-related stops tend to be shorter — the FAA lifts them once a thunderstorm passes or visibility improves. Stops caused by equipment issues or runway closures can last longer because they depend on repairs or maintenance.

The FAA does not announce how long a ground stop will last when it begins. Instead, they monitor conditions and lift the stop when it is safe to resume departures. Your airline will give you updates, but those estimates are often revised as conditions change. If you are stuck at the airport, check the FAA status page every 15 to 20 minutes rather than relying on a single announcement.

What to do if you are stuck in a ground stop

If you are at O'Hare during a ground stop, stay near your gate and keep your phone charged. Your airline will announce when the stop is lifted, and planes usually push back quickly once the FAA gives the go-ahead. Do not leave the airport or go through security again unless your airline tells you to rebook on a different flight.

If the ground stop lasts more than two hours, ask your airline about meals or hotel accommodations. You are not may have access to to compensation for a ground stop caused by weather, but many airlines offer meals or rebooking as a courtesy. If the stop was caused by an airline equipment issue or staffing problem, you may be may have access to to more — check your airline's delay policy.

If you have a connecting flight, tell a gate agent when ready. They can rebook you on a later flight if it looks like you will miss your connection. Do not wait until after your flight lands to ask.

Frequently Asked Questions

Can I get a refund if my flight is delayed by a ground stop?

No, not for weather-related ground stops. The FAA considers weather a circumstance beyond the airline's control, so you are not may have access to to a refund. You can rebook on another flight at no extra charge, or you can cancel and get a credit for future travel. If the ground stop was caused by the airline's equipment failure or staffing issue, refund rules may differ — ask your airline.

Will my flight be cancelled if a ground stop lasts too long?

Possibly. If a ground stop lasts several hours and it is late in the day, your airline may cancel the flight and rebook you on the next available departure. This is more likely on evening flights, since there is not enough time left to depart and arrive before the crew runs out of legal flying hours. Your airline will announce a cancellation before pushing back.

Do I have to stay on the plane during a ground stop?

Not always. If the ground stop is expected to last more than a few minutes, the airline may let passengers deplane and wait in the terminal. If you deplane, stay close to your gate and keep your phone on — planes can push back quickly once the stop is lifted. Ask a gate agent whether it is safe to leave the aircraft.

Can I see a list of past ground stops at O'Hare?

The FAA does not publish a public archive of past ground stops. However, you can search news reports or your airline's delay history if you are researching a specific date. The FAA status page only shows current and active conditions.

What is the difference between a ground stop and a travel ban?

A ground stop is temporary and affects only departures from one airport. A travel ban or flight ban is broader and usually issued by the government in response to a national emergency or security threat. Ground stops happen regularly; travel bans are extremely rare and would be announced by the FAA and your airline well in advance.
