When the FAA Grounds Every Flight, What Happens to the Planes Already Up There?

On November 13, 2026, the FAA issued a nationwide ground stop after communication problems hit air traffic control centres, an order the agency attributed to "extraordinary circumstances" and safety reasons. Transportation Secretary Sean Duffy confirmed technicians were investigating the disruptions. Only the second such nationwide stop since 9/11 (the other came in January 2023), it hit major hubs including Chicago O'Hare and Midway — and Flightradar24 counted more than 3,000 aircraft inbound to US airports at the moment it took effect.

Here's the part most passengers don't realise: a ground stop does not mean planes in the air have to land immediately or turn around. The order mainly blocks new departures, throttling the flow of aircraft entering the airspace. Flights still at their gates stay put until authorised to leave, but aircraft already airborne generally continue to their scheduled destination — and on November 13 the FAA let inbound flights land, handling international arrivals case by case.

Complications arise when the destination itself can't accept traffic, say during severe thunderstorms or a runway closure. In that case pilots may be told to fly a holding pattern until they get clearance to approach. If the disruption drags on, the plane diverts to another airport, leaving passengers to wait for a replacement flight or find other transport to their original destination.

Even once the stop is lifted, don't expect an instant return to normal. Controllers and airlines have to coordinate departures around gate availability and runway capacity, so some flights get new departure slots while others face long delays or cancellations — aircraft and crews may have been reshuffled across the network. For stranded travellers, the sensible moves are monitoring airline updates closely and, if the stop looks prolonged, booking a hotel or heading home if you live nearby.

Anyone flying in or to the US should know that ground stops are actually routine at the local level — weather and equipment failures trigger them regularly. Nationwide ones are the rare exception, but understanding the mechanics helps: airborne flights usually still land, diversions are the fallback rather than the rule, and the post-stop backlog is often the biggest source of delay.
