You wake up to an alert: the airline’s online check-in system went offline, and thousands of morning flights could be affected. Act quickly — check alternative boarding options, confirm your flight status, and arrive earlier than planned to avoid being stranded.
This post explains what caused the outage, how it can disrupt your travel timeline, and the practical steps you can take right now to protect your trip. Expect clear guidance on backup check-in methods, what rights apply if you miss a flight, and how to recover your itinerary without relying on the app.
What Happened: Online Check-In System Failure
Passengers faced a sudden loss of web and app access, inability to check in, and a temporary freeze on reservations and cancellations. The outage stemmed from a planned technology upgrade and data transfer that took systems offline for several hours.
Airline’s Urgent 24-Hour Warning
United issued a clear notice asking customers to check in a day early and use its website or mobile app before the update window began. The airline warned the system would be unavailable for roughly four-and-a-half hours during a scheduled transfer of data between data centers, and it advised travelers with morning flights to complete check-in the previous day to avoid problems.
Employees lost access to the same platforms, limiting gate and airport staff tools for processing changes. The airline said it rehearsed the transition and did not expect major issues, but it still recommended that customers carry printed or saved boarding passes when traveling during the outage.
Impact on Travelers: Stranded Passengers
When check-in portals go dark, passengers can’t retrieve itineraries, check bags, or get boarding passes through digital channels. That forced many travelers to queue at airport counters and kiosks, increasing wait times and leaving some temporarily stranded outside secure areas.
Airlines sometimes allowed late in-person processing, but those lines caused missed connections and stress for passengers with tight schedules. People without acceptable ID or with complex itineraries—like international connections or special-service requests—faced the biggest disruptions and needed direct staff help to proceed.
Controllable and Significant Delays
The outage created a mix of controllable and significant delays. Controllable delays occurred where airlines could have planned alternate staffing or provided temporary manual check-in procedures to reduce queues. Significant delays developed when the outage coincided with peak travel periods or when systems that manage seat assignments and baggage were offline.
Passengers experienced flight delays and missed connections that cascaded across schedules. Under DOT definitions, airlines may be required to report lengthy delays and could face scrutiny if failures reflect inadequate contingency planning for known, planned outages.
Response From the U.S. Department of Transportation
The U.S. Department of Transportation monitors major disruptions and can investigate whether an airline met operational and consumer-protection obligations. When outages cause widespread passenger harm, DOT may request incident reports, assess whether delays were avoidable, and review airline notifications to customers.
DOT attention typically focuses on whether the airline provided timely warnings, adequate staffing, and options such as rebooking or refunds for affected travelers. If DOT finds lapses in contingency planning for a planned outage, it can pursue enforcement or require corrective actions to protect passengers.
Your Rights and Recovery Options When Stranded
Passengers should document their situation, keep receipts for expenses, and insist on written confirmation of refunds, vouchers, or rebooking offers. Know the airline’s published policies and the DOT rules that may require automatic refunds in certain cases.
Claiming Refunds and Travel Vouchers
If an airline cancels a flight or makes a significant schedule change and the passenger no longer wants the trip, they can request a cash refund. DOT rules require refunds for canceled or significantly changed flights and for services paid but not delivered; passengers should ask to receive money back to the original form of payment rather than a travel voucher when eligible.
When the airline offers a travel voucher instead, the passenger should get the voucher details in writing: value, expiration date, blackout restrictions, and whether it is transferable. If the airline refuses a cash refund, save emails/screenshots and file a complaint with the airline first, then with DOT’s aviation consumer portal. Keep the booking reference and transaction receipts to speed up processing.
How to Get Rebooked or Redeem Frequent Flyer Miles
Airlines generally must rebook passengers on the next available flight when a disruption is airline-caused; passengers should request rebooking immediately at the counter, via the airline app, or by phone. If lines are long, use the carrier’s app or social media for faster service and capture any rebooking offer as written confirmation.
Passengers holding frequent flyer miles can ask to be reaccommodated using miles if that yields an earlier seat; they should verify award seat availability and any change fees before authorizing a miles redemption. For connections on partner carriers, request interline rebooking—airlines with commercial agreements often must honor it when they cannot carry the passenger themselves. Keep screenshots of offers, boarding passes, and any agent confirmations.
Handling Non-Refundable Tickets
Non-refundable tickets do not eliminate all remedies. If the airline cancels the flight or makes a significant change, the passenger is still entitled to a refund or rebooking at no extra charge. If the passenger voluntarily cancels because of a disruption, ask the airline for a credit voucher that preserves the ticket value minus only documented fees.
When a passenger needs to change plans and the ticket is non-refundable, inquire about same-day change options, fee waivers during major disruptions, or using travel insurance if purchased. Always ask for fee waiver confirmations in writing and save receipts for any out-of-pocket changes to support later reimbursement claims.
Compensation for Fueling or Overnight Issues
If a system outage or airline control issue causes a long delay, passengers can seek reimbursement for reasonable out-of-pocket expenses such as meals, ground transportation, or overnight lodging when the airline’s policy or agent confirms coverage. Request a written statement from staff that the disruption was airline-caused to strengthen a claim.
Passengers should keep itemized receipts and file expense claims promptly through the airline’s customer service portal. If the airline refuses reimbursement despite clear airline responsibility, escalate with the carrier’s customer relations and submit a DOT complaint with documentation. For fueling delays specifically, ask agents whether the delay was within the airline’s control; that detail affects eligibility for compensation or vouchers.
