Where to get delay information right now

The airline's website or app is your fastest source. Open your booking confirmation or search your flight number, and you will see the current status and any posted reason — mechanical issue, weather, air traffic control, crew delay, or other cause. Most airlines update this every 15 to 30 minutes once a delay is declared.

If the airline's system is slow or you are at the airport, ask a gate agent or call the airline's customer service line. The phone number is on your booking email or the airline's website. Gate agents often know details that have not yet posted online, especially about crew problems or mechanical work still in progress.

The FAA's Flight Delay Information System (at faa.gov) shows system-wide delays at major airports — useful if you want to know whether the delay is airport-wide or specific to your flight. The site lists the reason (weather, volume, equipment) but not individual flight details.

Key Takeaways

  • Check your airline's website or app first — it updates every 15 to 30 minutes and shows the stated reason for your delay.
  • Gate agents and airline phone lines often have more current information than the website, especially for mechanical or crew issues.
  • The FAA's Flight Delay Information System shows whether delays are airport-wide or weather-related, but does not track individual flights.
  • Weather delays are rarely changed once posted, but mechanical and crew delays can shift as repairs finish or crews arrive.
  • If you are owed compensation under DOT rules, the reason for the delay determines whether the airline must pay — weather and security issues typically do not trigger compensation.

What different delay reasons mean for you

The reason posted matters because it affects whether you are owed money. Weather delays — thunderstorms, snow, fog, high winds — are not the airline's responsibility under Department of Transportation rules, even if the delay is many hours. The airline must rebook you on the next available flight at no cost, but does not owe compensation.

Mechanical delays happen when the aircraft has a problem that must be fixed before takeoff. These can take hours if the issue is complex. Mechanical delays are the airline's responsibility, and you may be owed compensation if the delay is three hours or more at your destination. The airline must also provide meals and hotel if the delay stretches overnight.

Crew delays occur when the flight crew is late arriving or has exceeded legal flight hours. Like mechanical delays, these are the airline's responsibility and can trigger compensation. Air traffic control delays happen when the airport or airspace is congested — the FAA is managing the flow of planes. These are not the airline's fault, and compensation is not owed, though the airline must rebook you.

Security delays mean TSA or airport security is moving slowly. These are not the airline's responsibility. Other causes — passenger medical events, unruly passengers, baggage issues — vary in whether compensation applies. Ask the airline directly if the reason is unclear.

How to track changes as the delay develops

Delays often change. A flight might be delayed two hours for weather, then the weather clears and the delay shrinks to 45 minutes. Or a mechanical issue takes longer than expected and the delay grows. Check the airline's app or website every 20 to 30 minutes if you are waiting at the airport, or set up notifications if the app offers them.

Most airlines send text or email alerts when a delay is declared and again when the new departure time is set. Make sure your phone number and email are current in your booking. If you booked through a third-party site like Kayak or Expedia, the airline's direct notifications may not reach you — go to the airline's website to update your contact information.

Gate agents will announce changes over the airport speaker system, but do not rely on this alone if you are in a restaurant or bathroom. Check your phone regularly. If the delay is very long, ask a gate agent whether the flight is still expected to depart or whether it will be cancelled.

What to do if the reason seems wrong or is not posted

Sometimes the airline posts a vague reason like "operational delay" or does not post a reason at all. Ask a gate agent what the specific cause is — mechanical, crew, weather, or something else. They may not have the full story, but they can usually narrow it down. If they cannot, ask to speak to a supervisor or call the airline's customer service line.

If you believe the posted reason is inaccurate — for example, the airline says weather caused the delay but the sky is clear — document what you see. Take a photo or video of the weather conditions and note the time. If you later file a compensation claim, this evidence can help. However, understand that weather at the departure airport, the destination airport, or along the flight path can all cause delays, and you may not see the problem where you are standing.

Keep your booking confirmation and any written communication from the airline. If the airline sends you a delay notification by email or text, save it. These records help if you need to prove the delay length or reason later.

Understanding delays caused by the airline versus external factors

The airline is responsible for mechanical problems, crew scheduling, and staffing issues. These delays are within the airline's control, and you may be owed compensation if the delay reaches three hours at your final destination. The airline must also provide meals, hotel, and ground transportation if the delay is long enough.

External factors — weather, air traffic control, security issues, airport congestion — are not the airline's responsibility. The airline must rebook you on the next available flight and provide the same meals and hotel if needed, but compensation is not owed. The airline cannot control these delays, so the law does not require payment.

Some delays are mixed. For example, a mechanical issue might cause a two-hour delay, but then weather rolls in and extends it to five hours. In this case, the airline is responsible for the first two hours but not the additional three. Determining the exact split can be complicated, which is why many compensation claims end up in dispute.

How to request compensation if the delay qualifies

If your flight arrived three or more hours late at your final destination and the delay was the airline's fault (mechanical, crew, or other operational issue), you may be owed compensation under DOT rules. The amount is $250 for delays of three to six hours, $500 for delays of six or more hours, depending on the flight distance and other factors.

Contact the airline in writing — email or certified mail — within 30 days of the flight. Include your booking confirmation, flight number, scheduled and actual arrival times, and the reason for the delay. State that you are requesting compensation under 14 CFR Part 259. The airline has 30 days to respond with payment, a denial, or an offer to negotiate.

If the airline denies your claim or does not respond, you can file a complaint with the DOT's Aviation Consumer Protection Division at dot.gov. You can also pursue the claim in small claims court. Keep all documentation — booking confirmations, boarding passes, receipts for meals or hotel, and any written communication from the airline.

Frequently Asked Questions

Can I get my money back if my flight is delayed?

Refunds are not automatic for delays. You are owed a refund only if you choose not to fly and cancel your ticket. If you stay booked and the flight eventually departs, you are not owed a refund. You may be owed compensation (money beyond the ticket price) if the delay is three or more hours and the airline caused it, but this is separate from a refund.

What if the airline says the delay is weather but I do not see rain or snow?

Weather at the departure airport, destination airport, or anywhere along the flight path can cause delays. You may not see the problem where you are. Additionally, airlines sometimes ground planes for safety reasons related to weather forecasts, not current conditions. If you doubt the weather explanation, ask the gate agent for specifics — which airport has the weather, what type of weather, and when it is expected to clear.

How long can an airline delay a flight before they have to cancel it?

There is no set time limit. Airlines can delay a flight as long as they believe it will eventually depart. However, if a delay stretches past midnight or into the next day, the airline must offer you the choice to cancel and receive a refund or rebook on a later flight. Some airlines also have internal policies about maximum delay times before they cancel.

Do I get compensation if the delay was caused by weather?

No. Weather is considered an "act of God" and is not the airline's responsibility under DOT rules. The airline must rebook you on the next available flight and provide meals and hotel if the delay is long, but compensation is not owed. This applies even if the delay is 12 hours or more.

Where do I find the airline's phone number to call about my delay?

The phone number is on your booking confirmation email and on the airline's website. Search for "customer service" or "contact us" on the airline's homepage. If you are at the airport, ask a gate agent for the customer service number. Have your booking confirmation ready when you call.
