How to Change Your Flight During Airline System Outages or Technical Failures

Airline System Outages Can Upend Your Travel Plans—Here Is How to Take Control

Few things test a traveler's composure like arriving at the airport or checking a flight status only to discover that the airline's entire computer network is down. A system outage can prevent you from checking in, changing a seat, or even boarding your flight. When technical failures strike, the usual self-service tools and customer service channels often go dark at the exact moment you need them most.

While you cannot stop an outage from happening, you can prepare for one. Knowing exactly how to change your flight when the airline's systems are offline, how to reach a human agent, and what your rights are as a passenger can turn a chaotic situation into a manageable inconvenience. This guide walks you through every step of the process, from understanding why outages happen to executing a smooth rebooking under pressure.

Understanding Airline System Outages

Airline system outages occur when the central computer networks that manage reservations, check-ins, boarding, and flight operations experience a partial or total failure. These outages can affect a single airline or ripple across multiple carriers if they share infrastructure or rely on the same third-party providers.

Common Causes of Outages

Software glitches and updates gone wrong. Routine maintenance or a faulty software patch can crash reservation systems. In 2023, a major U.S. carrier experienced a widespread outage after a failed system update that grounded hundreds of flights for hours.
Cyberattacks and ransomware. Airlines are frequent targets. A distributed denial-of-service (DDoS) attack or ransomware can lock critical systems, forcing the airline to shut down online services to contain the threat.
Infrastructure failures. Power outages, data center cooling failures, or network hardware problems can take booking systems offline.
Third-party dependencies. Airlines often rely on global distribution systems (GDS) like Sabre, Amadeus, or Travelport. If the GDS goes down, multiple airlines lose the ability to manage reservations at once.
Human error. Misconfigured firewalls, accidental data deletions, or incorrect database commands can bring systems down temporarily.

Types of Outages and Their Impact on Flight Changes

Not all outages are the same. The type of failure directly affects your ability to change your flight:

Full system outage: The airline cannot access any reservation data. No changes can be made online or by phone. Airport agents may have to use manual check-in procedures, and rebooking may require writing paper tickets.
Partial outage: Some channels work while others do not. For example, the website might be down, but the mobile app functions, or vice versa. Airport kiosks might be offline while counter agents have limited access.
Communication outage: The airline's internal systems work, but customer-facing tools like the app, website, and phone lines are unavailable. In this scenario, going to the airport is often the best move.

How System Outages Affect Your Ability to Change a Flight

During an outage, the airline's workforce is operating under extreme pressure. Reservations agents cannot see your booking details, check seat availability, or process payments. The following breakdown illustrates what typically stops working:

Online check-in and seat selection: These features rely on real-time access to the booking database.
Flight change and cancellation portals: Any change that requires writing to the reservation system will fail.
Self-service kiosks at the airport: These are essentially terminals connected to the same backend that is down.
Phone queues: Call centers are flooded. Wait times can stretch to hours or even exceed the duration of the outage itself.
Live chat and social media bots: Automated responses typically cannot process changes, and human agents are overwhelmed.

Despite these challenges, changing your flight is still possible—it just requires a different approach than usual.

Proactive Steps to Take Before an Outage Happens

Preparation is your strongest tool. Before you ever encounter a system failure, take these steps to set yourself up for a smoother rebooking experience:

Save Your Booking Reference and Itinerary Offline

Do not rely solely on the airline's app or your email inbox. If systems are down, agents may need your booking reference (PNR) to look up your reservation manually. Write it down, take a screenshot, or keep a printed copy of your itinerary. Include the flight numbers, dates, and times for every segment.

Download the Airline App Before You Travel

During some partial outages, the mobile app remains functional even when the website is down. The app can cache certain data and may allow you to view your booking or request a change. Install the app and log in at home, where the network is stable, so you are ready to go.

Know the Airline's Partner and Alliance Network

When your flight is disrupted, the airline may rebook you on a partner carrier. Familiarize yourself with the airline's alliance (Star Alliance, oneworld, SkyTeam) and its codeshare partners. If you can suggest an alternative flight on a partner airline, you speed up the rebooking process.

Consider Travel Insurance with Trip Interruption Coverage

A good travel insurance policy can cover additional expenses incurred during a prolonged delay, including meals, accommodations, and alternative transportation. Read the fine print to understand how they handle "systems failure" or "technical breakdown" as covered events. NerdWallet's guide to travel insurance offers a solid overview of what to look for.

Immediate Steps to Take When an Outage Hits

The moment you realize the airline's systems are down, shift into action mode. Do not wait for the airline to contact you—act quickly to secure a change before seats fill up.

Verify the Scope of the Outage

Check the airline's official website, app, and social media accounts (Twitter/X, Facebook) for an announcement. Search for the airline's name plus "outage" or "system down" to see if other travelers are reporting the same issue. If the outage is widespread, the airline may issue a travel waiver that allows you to change your flight at no extra cost.

Use Alternative Contact Methods

Call the airline's international or regional number. Often, the main customer service line is swamped, but regional offices or dedicated elite-status lines have shorter queues.
Visit the airport in person. If you are near an airport, go to the airline's ticket counter. Agents there can sometimes process changes using backup systems or write manual tickets.
Try the airline's social media direct message feature. Some airlines have dedicated social media service teams that can initiate rebooking even when phone lines are jammed.
Use the app's messaging feature. If the app is partially functional, the in-app chat may connect you to an agent faster than a phone call.

Document Everything

Keep records of every interaction. Screenshot error messages, take photos of departure boards, save confirmation numbers for any changes made, and note the names and employee IDs of agents you speak with. If you incur expenses due to the outage—meals, hotel, ground transportation—save all receipts. You may need them for compensation claims later.

How to Change Your Flight During a System Outage

Changing a flight when the airline's reservation system is offline requires creativity, persistence, and a willingness to work with manual processes. Follow these strategies in order.

Attempt an Online Change First

Even if the main website is down, try the airline's mobile app. Some apps use a separate backend that may still be operational. Attempt to change your flight using the "Manage Booking" feature. If the system rejects the change, note the error code (if any) and move on to the next method.

Request a "Manual Rebooking" at the Airport

Airport agents often have access to backup systems or can use offline procedures to rebook you. If the outage is severe, they may write a manual ticket—a physical paper document that serves as your boarding authority. This process is slower than electronic rebooking, but it works.

When speaking to the agent, be ready with the following information:

Your booking reference and confirmation number
Your preferred alternative flight (have flight numbers and times ready)
Any elite status or travel insurance details
Whether you are willing to accept a partner airline or a different airport

Ask for Rebooking on a Partner Airline

If the airline's own flights are full or not operating, request a transfer to a partner airline. This is called "endorsement" in industry terms. The airline may issue an "endorsement letter" or a manual voucher that the partner airline can honor. Be prepared to accept a less convenient routing—sometimes a longer layover or a different arrival airport is better than waiting days for the next available seat.

Use a Third-Party Booking Service (with Caution)

If you booked through a third-party travel agency or online travel agency (OTA) like Expedia, Kayak, or Priceline, contact them directly. During widespread outages, OTAs can sometimes rebook you using their own inventory systems that run separately from the airline's backend. However, if you change your flight through the OTA without the airline's authorization, you may lose certain protections or refund rights.

Be Flexible with Dates, Airports, and Times

Rigidity is the enemy of a successful rebooking during an outage. If you can depart a day later, arrive at a different airport, or take a red-eye, you dramatically increase your options. Many airlines will waive change fees and fare differences during a declared system outage, so do not be afraid to propose alternatives that are significantly different from your original booking.

What to Do When the Airline Cannot Rebook You Immediately

Sometimes the system failure is so complete that no agent can make changes. In that case, you may need to wait for systems to come back online. While you wait, take these actions:

Get on a Waitlist (When Available)

Some airlines maintain a manual waitlist that agents can write your name onto. When the system comes back, the waitlist is processed first. Ask the gate agent or counter agent to add you to the standby list for the next flight to your destination.

Request a "Voluntary Change" or Refund for a Future Travel Credit

If you decide not to travel, ask the airline to issue a refund or a future travel credit. During a system outage, many airlines offer flexible rebooking policies that allow you to cancel for a full refund or a voucher valid for a year or more. Make sure you get the terms in writing before you leave the counter.

Know Your Passenger Rights

In the United States, the Department of Transportation requires airlines to refund passengers if the airline cancels or significantly changes a flight for any reason within the airline's control—including system failures. In the European Union, Regulation EC 261/2004 provides for compensation and care (meals, accommodation) in certain circumstances, though technical failures may be treated differently depending on whether they are considered "extraordinary circumstances." Check the U.S. DOT airline service page for current rules, or consult EU passenger rights information for European travel.

Compensation and Refunds After the Outage Is Over

Once the airline's systems are restored, you may have recourse for additional costs incurred. Document everything and submit a claim through the airline's customer relations portal or by mail.

When to File a Claim

You incurred out-of-pocket expenses for meals, hotels, or transportation due to the outage.
You missed a connection that was part of a single itinerary.
You were rerouted to a different airport and had to pay for ground transportation to your original destination.
You were forced to buy a ticket on another airline because the airline could not rebook you in a reasonable time.

What to Include in Your Claim

Your booking reference and flight numbers
Copies of receipts and invoices
Screenshots or photos of the outage (error messages, delay boards, official announcements)
Any written communication from the airline acknowledging the system failure
A clear explanation of the expenses you are requesting

Escalating If the Airline Denies Your Claim

If the airline rejects your claim or offers an unsatisfactory resolution, escalate to the relevant government authority. In the U.S., you can file a complaint with the Department of Transportation's Aviation Consumer Protection Division. In the UK, the Civil Aviation Authority handles airline complaints. Some travelers also use third-party services like AirHelp or FlightRight to pursue claims for a fee.

Future-Proofing Your Travel Plans Against Outages

While you cannot prevent an airline's technical failure, you can reduce its impact on your trip by adopting these habits:

Book Early and Avoid Tight Connections

When you book a connection with a short layover, even a minor delay caused by an outage can cause you to miss your next flight. Aim for connections of at least two hours for domestic flights and three hours for international flights, especially if you are traveling during peak periods or on an airline known for operational issues.

Carry a Backup Payment Method for Emergency Tickets

If the airline cannot rebook you and you must buy a ticket on another carrier, having a credit card with sufficient available credit can save you. Keep a secondary card or a travel money card as a fallback. Some credit cards offer trip interruption coverage that may reimburse you for the cost of an emergency ticket—check your card's benefits guide.

Join the Airline's Loyalty Program (and Hold Status)

Elite members frequently receive priority rebooking and dedicated phone lines that are less congested during outages. Even the lowest tier of status can put you ahead of general passengers in the rebooking queue.

Monitor Real-Time Outage Reports

Several websites track airline outages and IT incidents in real time. Downdetector aggregates user reports for major airlines and can show you the scope of a problem within minutes. Use this information to decide whether to head to the airport or wait at home.

Final Thoughts on Navigating Flight Changes During System Outages

Airline system outages are disruptive, confusing, and stressful—but they do not have to derail your travel plans entirely. By understanding how these failures work, preparing documentation ahead of time, and knowing exactly which steps to take when systems go dark, you position yourself to secure a flight change faster than travelers who wait passively.

The most effective strategy combines speed, flexibility, and polite persistence. Try the app first, head to the airport if the outage is severe, and always ask about partner airline rebooking. Document every interaction and every expense, because the compensation process begins when the systems come back online—not before.

Air travel is increasingly dependent on complex technology, and no system is infallible. The next time you hear that an airline's computers are down, you will already know exactly what to do.
