Check your airline's website or call them directly

The fastest way to know whether your flight is running is to log into your airline's website using your confirmation number and last name, or call the airline's customer service line. Most airlines show real-time flight status there — you will see whether the flight is on time, delayed, cancelled, or boarding. The airline's own system is the source of truth because they control whether the plane departs.

If you booked through a third-party site like Kayak, Expedia, or Google Flights, those sites pull information from the airline but may lag by a few minutes. Go directly to the airline instead if you need the most current picture. You can find the customer service number on your confirmation email or on the airline's homepage.

Have your confirmation number ready when you call. The airline will tell you the current status and, if the flight is delayed or cancelled, what your options are — usually rebooking on another flight or a refund.

Key Takeaways

  • Your airline's website or phone line shows the real-time status of your flight and is more current than third-party booking sites.
  • Flight status updates happen throughout the day as weather, mechanical issues, or crew problems develop or resolve.
  • If your flight is cancelled, the airline must offer you a rebooking or refund under federal rules.
  • Arriving at the airport early on a delay day lets you speak to an agent in person if you need to change flights.

What the different flight statuses mean

On Time means the flight is scheduled to depart at the time shown on your ticket. Delayed means the airline knows the flight will leave later than scheduled, and they will show you the new departure time. Cancelled means the flight will not operate at all that day. Boarding means passengers are currently getting on the plane and the flight is about to push back from the gate.

A flight can move between these statuses throughout the day. A flight marked delayed in the morning might be cancelled by afternoon if the problem cannot be fixed. A cancelled flight might be reinstated if the airline finds a replacement aircraft or crew. Check back every hour or so if your flight is delayed, especially if the delay is more than two hours.

Use flight tracking apps and websites for updates

Free sites like FlightAware, FlightRadar24, and the FAA's website show you whether a plane is actually in the air and where it is headed. These sites track the physical movement of aircraft, so they can tell you if a plane that was supposed to arrive at your departure airport is running late — which often cascades to your flight being delayed.

FlightAware also lets you enter your flight number and get notifications by email or text when the status changes. This is useful if you are not glued to your phone. The app will alert you if your flight is delayed, cancelled, or boarding so you do not have to keep checking manually.

These tracking sites are informational only — they do not control what the airline does. But they can give you a clearer picture of what is actually happening with the aircraft and crew assigned to your flight.

Understand why flights get delayed or cancelled

Weather is the most common reason for delays and cancellations. Thunderstorms, heavy snow, fog, and high winds can ground planes or slow down air traffic. Mechanical issues — a part that needs repair or inspection — can also delay a flight by hours while technicians work. Crew scheduling problems, such as a pilot or flight attendant not arriving on time, can push back departure.

The airline controls some of these factors and not others. They cannot control weather, but they can control whether they have enough crew scheduled and whether they maintain their aircraft properly. If an airline cancels many flights due to staffing, that is different from a cancellation due to a hurricane.

The reason matters for your rights. If your flight is cancelled due to weather, the airline is not required to pay you compensation, though they must rebook you or refund your ticket. If it is cancelled due to a mechanical issue the airline should have caught, you may be may have access to to compensation depending on your country's rules.

What to do if your flight is delayed

First, confirm the new departure time with the airline. Then decide whether you want to stay on the flight or explore other options. If the delay is long — more than three or four hours — ask the airline whether they will put you on an earlier flight to the same destination, even if it is on a different airline. Some airlines will do this at no extra cost if they cannot get you there on time.

If you are at the airport, go to the airline's ticket counter and speak to an agent. If you are at home, call the airline or check their website. Do not assume the flight will eventually leave on time just because the airline has not cancelled it yet. Delays can stretch, and you may miss a connection or have other plans that matter.

What to do if your flight is cancelled

The airline must offer you either a rebooking on the next available flight to your destination or a refund of your ticket price. You do not have to accept the first option they offer. If they want to rebook you on a flight three days later, you can ask for a flight the next day or request a refund instead.

If you paid for the ticket with a credit card, you can also dispute the charge with your card issuer if the airline refuses to refund you. Keep your confirmation email and any written communication from the airline about the cancellation.

If the cancellation strands you overnight, some airlines will pay for a hotel room and meals, though this varies by airline and the reason for the cancellation. Ask the agent at the counter or on the phone what the airline will cover.

Check for travel alerts or airport closures

Before you head to the airport, check whether your departure airport or destination airport has issued any travel alerts or temporary closures. The FAA website and local airport websites post notices when runways are closed, taxiways are blocked, or operations are suspended due to weather or other emergencies.

If your destination airport is closed, your flight will not land there, and the airline will either delay the flight until the airport reopens or cancel it. Knowing this ahead of time saves you a wasted trip to the airport.

Frequently Asked Questions

How often does flight status update?

Airlines update flight status continuously throughout the day as conditions change. Major updates — a delay announcement, a cancellation, or a gate change — usually appear within 15 to 30 minutes of the decision. Check your airline's website or app an hour before your scheduled departure to catch any last-minute changes.

Can I get a refund if my flight is delayed but not cancelled?

A delay alone does not may have access to you to a refund under U.S. federal rules. You are may have access to to a refund only if the flight is cancelled or if you choose not to fly and ask for your money back. Some airlines offer travel credits or vouchers for long delays, but this is their choice, not a requirement.

What if I miss my flight because of a delay on a connecting flight?

If the delay is the airline's fault and you miss your connection, the airline must rebook you on the next available flight at no extra cost. If the delay is due to weather, the airline still must rebook you, but they may charge you a change fee depending on your ticket type and their policy. Call the airline as soon as you know you will miss the connection.

Do I have to go to the airport if my flight is delayed?

No. If your flight is delayed, you can wait at home until the airline announces a new departure time. However, arrive at the airport at least two hours before the new departure time (or three hours for international flights) to allow time for check-in and security. The airline can close the gate and leave without you if you are not there by the cutoff time.

Will the airline text or email me if my flight status changes?

Most airlines send automatic notifications to the email address on your booking, but not always to your phone. Sign up for the airline's app or use a flight tracking service like FlightAware to get text or push notifications. This way you will know when ready if something changes and do not have to keep checking manually.
