What Happens To Planes Already In The Air When The FAA Grounds Every Flight?

Imagine sitting on a plane tens of thousands of feet above the ground when the Federal Aviation Administration (FAA) suddenly announces that all departing flights nationwide are grounded. For flyers, that news might sound concerning (and even scary if you're already anxious about flying). Questions might begin swirling through your head. Does the pilot have to turn around, or will the plane be diverted to another airport? What happens to the thousands of planes already flying across the country?

Airlines operate around the clock, so a nationwide ground stop will almost certainly take effect while planes are already in the sky. And these questions were brought up by many passengers on November 13, 2026, when the FAA ordered a nationwide ground stop following communication problems affecting air traffic control centers. According to The Independent, the agency said the order came due to "extraordinary circumstances" and "safety reasons," while Transportation Secretary Sean Duffy confirmed that technicians were investigating the communication disruptions. The stop affected airports across the country, including Chicago's O'Hare and Midway, where many flights experienced delays. Making things even more complicated, Flightradar24 reported that there were more than 3,000 planes headed to U.S. airports at the time the ground stop went into effect.

However, a ground stop doesn't mean that planes already in the air must land immediately. A ground stop mainly prevents affected flights from taking off, reducing the number of aircraft entering the airspace. According to the FAA's official procedures, flights covered by a ground stop must stay put at their departure airports until they're authorized to leave. But what happens for passengers already airborne depends on the reason for the ground stop and conditions at their destination.

Although smaller ground stops happen often, nationwide ground stops are rare. In fact, the November 13 incident was only the second nationwide ground stop since the terrorist attacks of September 11, 2001, following one in January 2023. The FAA may ground flights for anything from severe weather to equipment failures, airport closures, or other safety conditions. For passengers already in the air during a ground stop, the flight will usually continue toward its scheduled destination. During the November 13 ground stop, the FAA allowed aircraft already in the air to land, focusing instead on preventing additional planes from taking off. The FAA also handled international flights headed to the U.S. on a case-by-case basis.

However, things can get more complicated when severe thunderstorms, runway closures, or other conditions prevent an airport from accepting incoming flights. Pilots could be instructed to enter a holding pattern, meaning the aircraft follows a designated route while waiting for clearance to approach the airport. If the disruption continues, pilots may even need to divert their plane to a different airport. Passengers on diverted flights may have to wait for a replacement flight or arrange alternative transportation to reach their original destination.

Also, once a ground stop is lifted, flights don't necessarily take off right away. Controllers and airlines have to work together to coordinate new departures, available gates, and runway capacity. Some flights may be assigned new departure times, while others might face longer delays or even be canceled, especially when aircraft and crews have been shuffled around. For passengers stuck due to a ground stop, the best thing to do is monitor updates from their airline for next steps. Since ground stops can last for a while, booking a hotel or heading home if you live nearby may make sense during a prolonged disruption.
