What Is an FAA Ground Stop?
A ground stop is an order from the FAA's Air Traffic Control System Command Center that prevents aircraft from departing for one or more specific airports. During a nationwide ground stop, no flights depart from any U.S. airport.
Ground stops are different from ground delays. A ground delay program slows departures by assigning each flight a specific departure time — flights still leave, just later. A ground stop means nothing moves.
The FAA typically issues ground stops for three reasons:
- Weather — severe thunderstorms, snow, or low visibility at a destination airport
- Equipment failure — radar outages, communication system failures, or NOTAM system issues
- Security — rare, but the FAA can ground flights for national security reasons
Most ground stops affect individual airports and last 30 minutes to 2 hours. Nationwide ground stops are extremely rare — only three have occurred this century.
What You Should Do Right Now
If you're at the airport
- Stay near your gate — flights can resume quickly when the stop lifts
- Don't get in the rebooking line yet — wait for your airline to update your flight status
- Charge your phone — you'll need it for rebooking
- Screenshot your booking — you'll want proof of your original itinerary
If you haven't left for the airport
- Do not go to the airport until your flight status is confirmed as departing
- Check your airline app every 15-30 minutes for updates
- Look for change fee waivers — airlines typically post these within an hour of a major disruption
If your flight is cancelled
- You're entitled to a full cash refund — not a voucher
- Rebook ASAP — seats on tomorrow's flights fill fast
- Consider alternate airports if your primary is overwhelmed
- File a complaint with the DOT if your airline refuses a refund
