The short answer

A delay feels like something is wrong. Usually it means the opposite: someone decided to wait for better weather, for space in busy airspace, for a crew to be ready, or for a check to be finished. Waiting on the ground is how aviation stays safe.

DOT's consumer guide puts it plainly: airlines don't guarantee their schedules, because weather, air traffic and mechanical issues are hard to predict.¹ What you do have are some clear rules and a few useful tools.

First, a few practical steps

Check your airline's app. It usually has the newest departure time and gate, and often lets you rebook yourself.
Look at the bigger picture. The FAA's airspace status page shows airport delays and ground programs, like a ground stop for storms.⁵
Ask about your options. DOT notes that on a long delay you may be better off moving to another flight, and that sometimes it's easier to arrange by phone than in the gate line.¹
Stay near the gate if the delay is short. Times can move earlier as well as later.
Look after yourself. Eat, drink water, charge your phone. The breathing timer is there if the waiting gets to you.

What the rules guarantee

A refund for a significant delay. If your flight is significantly delayed and you decide not to travel, or don't accept a rebooking or credit, you're entitled to a refund under DOT rules, regardless of the reason.⁴ For this rule, a significant delay or change includes arriving 3 hours or more late on a domestic itinerary, or 6 hours or more on an international one.⁴ If you take the flight anyway, the refund doesn't apply. Our cancelled flight page explains the refund rule in full.

Limits on long waits on the tarmac. For flights at US airports, airlines generally must begin returning to the gate, or let passengers off, before 3 hours on domestic flights and 4 hours on international flights. There are exceptions for safety, security and air traffic control reasons. During a tarmac delay you must get food and water within 2 hours, working toilets, comfortable cabin conditions, medical attention if needed, and status updates every 30 minutes.³

What the rules don't guarantee

DOT says there are no federal requirements about what airlines must do for passengers waiting at the airport during a delay, such as meals or a hotel. Each airline sets its own policy, and some offer more when the cause is within their control.¹

That's where the DOT Airline Cancellation and Delay Dashboard helps. It shows, airline by airline, what the largest US carriers have committed to when a delay is caused by something within their control, such as maintenance or crew issues: for example meal vouchers on longer delays, or a hotel when you're stuck overnight.² Commitments differ between airlines and can change, so check the dashboard and your airline's customer service plan rather than relying on memory.⁶

If it's a weather or air traffic delay

These delays are the safety system working exactly as designed. Air traffic control spaces airplanes out when storms block routes or an airport can handle fewer arrivals, so flights wait on the ground instead of circling in the air. It's a good trade: a calm wait at the gate instead of a bumpy detour. The program day on weather and delays goes deeper on why.

The calm takeaway: a delay is the system choosing caution. You have real protections, including tarmac limits and a refund if a long delay means you'd rather not fly, and the DOT dashboard shows what your airline has promised on top.

Quick answers

Does an airline have to compensate me for a delay?

There's no federal requirement for airlines to provide meals or hotels during a delay; each airline sets its own policy. DOT's Airline Cancellation and Delay Dashboard shows what the largest US airlines commit to when the delay is within their control.

Can I get a refund if my flight is very delayed?

Yes, under DOT rules, if your flight is significantly delayed (arriving 3 or more hours late domestically, or 6 or more hours internationally) and you choose not to travel or accept an alternative, you're entitled to a refund.

How long can I be kept on a plane on the tarmac?

For flights at US airports, airlines generally must begin moving the plane back to the gate, or give passengers a chance to get off, before 3 hours on domestic flights and 4 hours on international flights, with exceptions for safety, security or air traffic control reasons.

How can I check why flights are delayed?

The FAA's National Airspace System status site shows airport delays and ground programs, such as weather-related ground stops. Your airline's app has the latest on your specific flight.
