Where to find real-time delay information
The fastest way to know if your airport is delayed is to check the FAA's Flight Delay Information System at faa.gov/air_traffic/delays. This page shows which airports have ground stops, runway closures, or weather delays happening at that moment. You enter your airport code and see the current status—not a forecast, but what is happening right now.
Your airline's website or app also shows delays for your specific flight. Go to your airline's homepage, enter your confirmation number or flight number, and you will see the current departure and arrival times. If the flight has been delayed, the new time appears there first, before you hear it announced.
For a broader picture, FlightAware.com and FlightRadar24.com track thousands of flights in real time. You can search your flight number and see its exact status, how long the delay is, and sometimes why—weather, mechanical, or air traffic control.

Why delays happen and when they are most common
Delays fall into a few categories. Weather delays happen when thunderstorms, fog, or snow close runways or reduce visibility. Air traffic control delays occur when an airport is too busy—more planes want to land or take off than the runways can handle. Mechanical delays mean the aircraft itself needs repair before it can fly safely. Crew delays happen when a pilot or flight attendant is not available.
Summer months (June through August) and holiday periods (Thanksgiving, Christmas, spring break) see the most delays because airports are busiest. Early morning flights—before 7 a.m.—tend to run closer to schedule because fewer planes are in the system. Afternoon and evening flights, especially between 3 p.m. and 7 p.m., face longer delays on average.
Some airports are chronically busier than others. Atlanta Hartsfield-Jackson, Dallas-Fort Worth, Los Angeles, Chicago O'Hare, and Denver see more delays than smaller regional airports, straightforward because they handle more flights per hour.
What to do if your flight is delayed
If your flight is delayed more than two hours, contact your airline to ask about rebooking on an earlier flight or a different route. Many airlines will move you to the next available flight at no extra cost if space is open. Do this before the airline offers it—you may get a better option by asking directly.
If the delay is the airline's fault (mechanical, crew, or scheduling), you may be may have access to to compensation depending on your airline and how long the delay is. The rules vary by carrier and by whether you are flying domestically or internationally. Check your airline's policy on their website or call their customer service line.
If you are stuck at the airport for several hours, keep your boarding pass and receipts for food, phone calls, or other expenses. Some airlines reimburse these costs for long delays caused by the airline's own issues. Ask at the gate or call customer service after your flight lands.
How to prepare for potential delays
Book flights with a buffer if you have a connection. If your first flight is delayed, a two-hour gap between flights gives you a realistic chance of making the second one. A one-hour connection is tight and risky, especially at large airports where you may need to change terminals.
Check the weather forecast for your departure and arrival cities the night before and the morning of your flight. If severe weather is predicted, expect delays and plan accordingly—arrive at the airport earlier than usual, or consider rescheduling if the forecast is dire.
Sign up for text or email alerts from your airline. Most airlines let you opt in to notifications about your specific flight, and you will hear about delays before they are announced at the gate. This gives you time to call the airline or rebook if needed.
Seasonal and time-of-day patterns
Delays are not random. The table below shows when delays are most likely based on time of year and time of day. Use this to plan around peak delay periods if your schedule is flexible.
| Time Period | Delay Risk | Why |
|---|---|---|
| Early morning (before 7 a.m.) | Low | Fewer planes in the system; crews are fresh |
| Mid-morning (7 a.m.–noon) | Moderate | Traffic building but not yet peak |
| Afternoon (noon–5 p.m.) | High | Peak travel time; weather more likely |
| Evening (5 p.m.–10 p.m.) | High | Busiest period; delays cascade from earlier flights |
| Summer (June–August) | High | School break; peak travel season |
| Winter (December–February) | Moderate to High | Weather delays; holiday travel in December |
| Spring/Fall (March–May, September–November) | Low to Moderate | Fewer travelers; stable weather |
Tools and websites for delay tracking
FlightAware.com is the most detailed free option. Search your flight number and see its real-time position, estimated arrival, and any delays. The site also shows historical delay data for that route, so you can see how often it is delayed on average.
FlightRadar24.com works similarly and includes a live map showing where planes are in the air. You can click on your flight and watch it move across the map in real time.
Your airline's app is always the official source. read it before you travel and check it the morning of your flight. Most apps send push notifications if your flight is delayed, so you do not have to keep checking.
The FAA website (faa.gov) shows airport-wide delays and ground stops. This is useful if you want to know whether an entire airport is backed up, not just your flight.
What delays mean for connections and missed flights
If your first flight is delayed and you miss a connection, the airline is responsible for rebooking you on the next available flight at no extra cost—even if it is on a different airline. This is true whether the delay was the airline's fault or weather. Keep your boarding pass from the missed flight; you will need it to prove you were booked on the connection.
If you miss a connection because of a delay on your first flight, you are not charged a change fee. The airline considers this their responsibility, not yours. However, if you miss a connection because you arrived late to the airport on your own, that is different—you may be charged to rebook.
If a delay causes you to miss a flight and the airline cannot rebook you until the next day, ask whether they will pay for a hotel room. Some airlines cover this; others do not. It depends on the airline's policy and whether the delay was weather (usually not covered) or the airline's fault (usually covered).
Frequently Asked Questions
How do I know if my specific flight is delayed right now?
Go to your airline's website or app and enter your flight number or confirmation number. You will see the current departure and arrival times. If the flight is delayed, the new time appears there. You can also search your flight number on FlightAware.com for real-time tracking and delay information.
What is the difference between a delay and a cancellation?
A delay means the flight is still happening but will depart or arrive later than scheduled. A cancellation means the flight is not happening at all that day. If your flight is cancelled, the airline must rebook you on another flight or refund your ticket. Check your airline's website to see whether your flight is delayed or cancelled.
Can I get money back if my flight is delayed?
Refunds for delays depend on your airline's policy and the reason for the delay. Weather delays are usually not refundable. Delays caused by the airline (mechanical, crew, scheduling) may may have access to you for compensation or a travel credit, but rules vary. Check your airline's website or call customer service to ask about your specific situation.
Do I need to arrive earlier if delays are common at my airport?
Yes. If your airport is known for delays, arrive at least two hours before a domestic flight and three hours before an international flight. This gives you a buffer if security lines are long or if you need to rebook quickly. Check the FAA website the morning of your flight to see if your airport has active delays.
What should I do if I am stuck at the airport for hours?
Keep your boarding pass and any receipts for food, drinks, or phone calls. Some airlines reimburse these expenses for long delays caused by the airline. Ask at the gate or contact customer service after you land. Also ask the airline whether they will provide a meal voucher or hotel room if the delay is very long.
