Flight Cancelled or Delayed: What Should You Do?

The first 10 minutes after a cancellation or delay announcement are the most valuable. Seats on alternative flights disappear fast at large hubs during a system-wide disruption, and the passengers who act first get the best options. Here is the sequence that works:

1. Open the airline app immediately. Do not walk to the gate agent desk first. The app shows live seat availability across all routes and lets you rebook without waiting. Search beyond the obvious direct route: a connection through a different hub city often departs sooner than the next direct flight on your original route.
2. Call the airline's rebooking line at the same time. Save the number in your phone before you travel. If you hold any elite status tier, use the dedicated line rather than the general number. Put the call on speaker while you also work the app, so you are moving on two channels simultaneously.
3. Stay near the gate until you have a confirmed seat. Gate agents can access standby inventory and, in some cases, endorse your ticket onto a partner carrier under an interline agreement. That option is not always visible in the app.
4. Photograph every receipt from this moment forward. Meals, ground transport, accommodation: all of it. You will need documentation to file a reimbursement claim if the disruption qualifies under the airline's customer service plan (published under 14 CFR Part 259.5).
5. Contact your booking channel in parallel. If you booked through a third-party online travel agency or a travel agent, they hold the ticket. The airline may not be able to rebook you until the booking channel releases the reservation.

Practical note: at large hub airports, airline customer service desks in the main terminal (outside the secure zone) sometimes have shorter lines than gate agent desks inside security. If you need to exit security to reach one, make sure you have everything you need to re-clear, including your ID and any carry-on you cannot leave behind.

US passenger rights for cancellations rest on two pillars: DOT regulations and each airline's published customer service plan.

The right to a refund

The DOT's April 2024 Refund Rule, codified at 14 CFR Part 259, makes the refund entitlement explicit: if the airline cancels your flight or makes a significant change to your itinerary, you are entitled to a full refund to your original payment method. This applies regardless of the reason, including weather or air traffic control. You are not obligated to accept a travel voucher, a future credit or a rebooking you do not want. If an airline resists, file a complaint at transportation.gov/airconsumer.

Delay compensation: what the US does and does not require

The United States has no federal statute mandating fixed cash compensation for flight delays, in contrast to the European Union's EC Regulation 261/2004 (Article 7), which sets compensation of 250 to 600 euros based on flight distance. In the US, what you receive for a delay depends on:

• The airline's customer service plan, required to be published and accessible under 14 CFR Part 259.5. This plan specifies what the airline commits to providing for controllable delays (mechanical problems, crew scheduling) versus non-controllable ones (weather, ATC). Read it before you travel.
• Whether the disruption was within the airline's control. Controllable disruptions typically trigger meal vouchers and, for overnight delays, hotel accommodation. Weather delays typically do not.
• Your travel insurance or credit card benefits. Trip delay and cancellation protection on many travel credit cards covers expenses the airline will not. Check your card's benefits guide or call the benefits line before paying out of pocket.

How to escalate if commitments are not met

Document what the airline told you, the name of the agent if possible, and the time of the conversation. Submit a written reimbursement claim through the airline's website. If the airline does not respond or denies a valid claim, file a complaint with the DOT Office of Aviation Consumer Protection at transportation.gov/airconsumer.

The practical sequence below reflects how hub-airport disruptions actually play out: seats fill in minutes, not hours, and passengers who use multiple channels simultaneously get the best outcomes.

Step 1: Use the airline app before anything else

Airline apps pull live inventory and let you select and confirm an alternative flight without speaking to anyone. During a hub-wide disruption, this is almost always faster than any queue. Look at all available routes, not just direct flights: a two-stop itinerary that departs in 90 minutes may be a better outcome than a direct flight the next morning.

Step 2: Call the airline's rebooking or elite line simultaneously

Have the number saved before you travel. General customer service lines can be busy during large disruptions, so if you hold any status tier, use the dedicated number. Some airlines also accept rebooking via live chat or social media direct message (Twitter/X, for example), which can be faster than a phone queue when call volumes are high.

Step 3: Ask about interline and codeshare options

If no seats are available on your original carrier, ask the gate agent or phone agent whether your ticket can be endorsed onto a partner airline under an interline agreement. This is more common on international itineraries but is sometimes available domestically. The agent will know what agreements apply to your ticket type and fare class.

Step 4: Consider a nearby airport if the situation is severe

During a hub-wide ground stop or multi-hour delay, a nearby airport served by a competing carrier may have available seats. This requires you to arrange and pay for your own ground transport, so weigh the full cost and time against the benefit before committing.

Commercial interest disclosure: Airport Online publishes airport information pages, including atl.airportonline.org for Atlanta Hartsfield-Jackson, where travellers can find ground transport options, terminal maps and nearby hotel information. We mention it here because that kind of resource is practically useful when you are stranded and need to move quickly.

An overnight disruption at a large hub is stressful but manageable if you move through the following steps in order.

Confirm what the airline will cover before you spend anything

Ask the gate agent or call customer service immediately. Airlines that publish a customer service plan under 14 CFR Part 259.5 typically commit to hotel accommodation and meal vouchers for controllable cancellations. They are not required to cover weather-related cancellations. Get the answer in writing if you can, such as a confirmation email or a screenshot of the voucher code.

Book accommodation as soon as you know you need it

Airport-adjacent hotels fill quickly during large disruptions. Do not wait for the airline to confirm coverage before searching. Book a refundable rate so you can cancel if the airline provides a voucher. Confirm any transport arrangements and costs directly with the hotel or shuttle provider before booking.

Sort out your checked bags

If your bags were already checked when the flight was cancelled, ask the airline whether they will be held at the airport or returned to baggage claim. You may need clothing or medication from them for an overnight stay. The airline's baggage service desk, separate from the gate agent desk, handles this.

Document every expense from this point forward

Meals, ground transport to and from the hotel, and the hotel itself are all potentially reimbursable for controllable disruptions. Photograph receipts immediately. Submit your reimbursement claim through the airline's website within the window specified in its customer service plan, and confirm that window with your carrier, as it varies.

Use airport resources to move faster

Airport information pages give you a fast way to find 24-hour dining, charging stations, ground transport options and nearby hotels without searching multiple sites. For Atlanta Hartsfield-Jackson, atl.airportonline.org covers these in detail. For other airports, check the airport's official website.

This guide addresses the most common disruption scenarios for domestic travellers at US commercial airports. Several important situations fall outside its scope:

• International itineraries. Flights to or from EU airports may trigger rights under EC Regulation 261/2004 (Articles 5-9), including fixed cash compensation and the right to care. Flights covered by the Montreal Convention (for baggage loss or personal injury) follow different rules. This guide does not substitute for advice on those frameworks.
• Award tickets and third-party bookings. Passengers who booked with miles, points or through a third-party online travel agency may face different rebooking processes and refund timelines. Check directly with the booking channel.
• Passengers with disabilities. Additional DOT rules under 14 CFR Part 382 govern the treatment of passengers with disabilities during irregular operations, including priority rebooking and specific assistance requirements. Contact the airline's accessibility desk directly.
• Specific airport amenities, hotel names and shuttle costs. This guide does not name or recommend specific hotels, lounges or shuttle services at any airport, because availability and pricing change. Check the airport's official website or a current airport information page for up-to-date options, and confirm all costs directly with the provider.
