United Airlines is not permanently grounded, but individual flights are delayed or cancelled regularly
United Airlines operates thousands of flights daily across the United States and internationally. When you hear that "United flights are grounded," it usually means a specific airport, route, or fleet has a temporary ground stop — not the entire airline. A ground stop can last anywhere from a few minutes to several hours, depending on the cause.
The most common reasons for United flight delays and cancellations are weather, air traffic control delays, mechanical issues, crew scheduling problems, and staffing shortages. During severe weather events like thunderstorms or winter storms, the FAA (Federal Aviation Administration) may issue a ground stop that affects multiple airlines at once, not just United.
To find out whether your specific United flight is affected right now, you need to check the airline's real-time status tools rather than relying on general news reports, which often lag behind actual conditions by 30 minutes or more.
Key Takeaways
- United flights are delayed or cancelled on a regular basis due to weather, mechanical issues, or crew problems, but the entire airline is rarely grounded at once.
- The fastest way to check if your flight is affected is to enter your confirmation number on United's website or call 1-800-864-8331 to speak with a representative.
- The FAA's website shows active ground stops at specific airports, which affect all airlines, not just United.
- If your flight is cancelled, United will rebook you on the next available flight at no extra charge, or you can request a refund of your ticket price.
How to check United flight status in real time
Go to united.com and select "Manage Reservations" at the top of the page. Enter your confirmation number (a six-character code from your booking email) and your last name. The system will show your flight's current status — on time, delayed, or cancelled — along with the gate number and boarding time if the flight is still operating.
If you do not have your confirmation number, you can search by entering your flight number and the date. United's flight number always starts with "UA" followed by four digits (for example, UA 456). You can also call United's customer service line at 1-800-864-8331 and provide your name and flight details; a representative will tell you the status when ready.
For a broader view of delays across the airline, visit United's Flight Status page at united.com/en/us/fly/flight-status. This page shows delays and cancellations by airport and time of day, which helps you understand whether the problem is widespread or isolated to your specific flight.
Understanding FAA ground stops and what they mean for United
When the FAA issues a ground stop, it orders all aircraft at a specific airport to remain on the ground until conditions improve. This is different from a delay — a ground stop is a complete halt of departures. Ground stops typically happen during severe weather, when air traffic control systems are overwhelmed, or after security incidents.
A ground stop affects every airline operating at that airport, not just United. If you see news that flights are grounded at Chicago O'Hare or Denver International, that applies to American, Southwest, Delta, and all other carriers there too. The FAA publishes active ground stops on its website at faa.gov/air_traffic/advisories/ground_stops, updated every few minutes.
Ground stops usually last between 30 minutes and 2 hours, though severe weather can extend them longer. Once the FAA lifts the ground stop, flights resume in the order they were scheduled, which means your flight may not depart when ready even after the stop ends.
What to do if your United flight is cancelled
If United cancels your flight, the airline will automatically rebook you on the next available United flight to your destination at no extra charge. You do not have to call or visit the airport — United sends a notification to the email address on your reservation with your new flight details and confirmation number.
If the new flight does not work for you, you have two options. You can request a refund of your ticket price by logging into your United account under "Manage Reservations" and selecting "Request a Refund," or you can call 1-800-864-8331 and ask to be rebooked on a different airline. If United caused the cancellation (mechanical issue, crew problem, or overbooking), the airline must rebook you on a competitor's flight at no extra cost if no United flight is available within a reasonable timeframe.
Keep your original confirmation number and any emails from United about the cancellation. If you paid with a credit card and United does not process your refund within 30 days, you can dispute the charge with your card issuer.
Delays versus cancellations: what each means for your trip
A delay means your flight will depart later than scheduled but will still operate that day. United typically notifies passengers of delays through email, text, or the United app if you have notifications turned on. A delay of one to two hours is common during busy travel periods or bad weather; delays of four hours or more are less frequent but happen during major storms or system failures.
A cancellation means the flight will not operate at all that day. United will not charge you a change fee to rebook on a later flight, and you are may have access to to a refund if you prefer not to travel. If a cancellation happens within 24 hours of your departure, you may also be may have access to to compensation under Department of Transportation rules, though United will not mention this — you have to request it.
If your flight is delayed more than three hours and you miss a connection as a result, United will rebook you on the next available flight to your final destination at no charge. If the delay causes you to miss a hotel reservation or event, United's standard policy does not cover those costs, but you can file a claim with your travel insurance if you purchased a policy that includes delay coverage.
Checking for system-wide issues at United
Occasionally United experiences a technical outage that affects its booking system, website, or flight operations across multiple airports. During these events, the airline's website may be slow or unavailable, and you may not be able to check your flight status online.
If United's website is down, call 1-800-864-8331 to reach a representative. United also posts updates about major outages on its social media accounts (Twitter @united and Facebook.com/United) and sends notifications through the United app if you have it installed. These outages are rare and usually resolved within a few hours.
You can also check whether United is experiencing widespread delays by visiting FlightAware.com and searching for "United Airlines." FlightAware tracks all commercial flights in real time and shows the percentage of United flights that are delayed or cancelled. If more than 10 percent of United's flights are delayed, the airline is likely dealing with a system-wide issue.
What happens if you miss your United flight
If you miss your flight because of a delay on a connecting flight, United will rebook you on the next available flight at no charge. Bring your original boarding pass and the boarding pass from the delayed flight to the United counter, and a representative will issue a new ticket when ready.
If you miss your flight for any other reason (traffic, oversleeping, arriving late at the airport), United will charge you a change fee to rebook on a later flight, unless you purchased a flexible ticket or have elite frequent flyer status. The change fee is typically $75 for domestic flights and $100 for international flights, though this varies by ticket type.
If you miss your flight and do not rebook, your ticket is forfeited and you will not receive a refund. United does not offer standby flights on other airlines if you miss your departure, so your only option is to purchase a new ticket or rebook on a later United flight.
