Tomorrow, February 4, 2026, United Airlines is preparing for a significant system outage that would impact hundreds of passengers, including those heading to Canada, Brazil, Mexico, France, and Germany. This scheduled disruption is a component of an important technological upgrade that will improve the airline’s reservation system. During the outage, passengers will not be able to book flights, check in, or make changes to their reservations due to the temporary unavailability of web and app services. Travellers are advised to finish check-in and make any necessary adjustments before the system goes offline at 1:30 AM CST tomorrow, even though this upgrade is anticipated to increase the airline’s efficiency and system reliability in the long run. Passengers are urged to exercise patience as the shutdown may cause service delays, but United Airlines is trying to guarantee a seamless transition for the numerous foreign travellers impacted.
What to Expect During the Shutdown
United Airlines confirmed in an official statement:
“We’re conducting a planned technology upgrade on Wednesday, February 4 from 1:30 – 5:00 AM CST and many of our web and app services will NOT be available for anyone during that time, including United employees. You can book, complete check-in, or make trip changes prior to February 4 at 1:30 AM CST or when the technology upgrade is complete.”
During this time, travelers will be unable to complete check-ins, make bookings, or alter any trip details through United’s website or mobile app. Additionally, United employees will be unable to access internal systems, which could lead to further delays in assistance.
The airline has confirmed that its reservation system, known as Shares, will undergo an important data transfer from its North Carolina data center to the Chicago data center. This upgrade is essential for improving system reliability and ensuring a smoother experience for future bookings and check-ins. While the airline has rehearsed the data transfer transition, United acknowledges that disruptions are inevitable and has urged customers to plan accordingly.
Key Details for Travelers
United Airlines has stressed that passengers flying tomorrow morning are strongly encouraged to check in prior to 1:30 AM CST to avoid any complications. Travelers can “book, complete check-in, or make trip changes prior to February 4 at 1:30 AM CST or when the technology upgrade is complete.” Those who have flights scheduled during the affected period should complete their check-ins and make any necessary changes to their bookings before the system downtime begins.
For travelers who miss this window, the airline recommends checking in as soon as the system is back online after 5:00 AM CST. Although the airline has promised that all systems will be up and running soon after the upgrade is complete, the timing is critical for those with early morning flights.
Why is the System Shutdown Happening?
United Airlines is conducting the system shutdown as part of a planned technology upgrade. The primary aim of this upgrade is to enhance the airline’s reservation system’s efficiency and reliability. As airlines continue to grow, updates to their systems are necessary to handle an increasing volume of passengers, bookings, and data. By transferring data to a more modern data center, United aims to boost the overall performance of its platform, which will help improve customer experiences in the future.
What Should Travelers Do?
Travelers planning to fly with United on February 4 should take the following precautions:
- Check-in Early: Ensure that you complete check-in via United’s website or mobile app before 1:30 AM CST on February 4.
- Review Your Booking: Make any necessary changes or confirm your flight details ahead of the scheduled shutdown time.
- Be Patient: Understand that the system will be down during the specified hours, and there may be delays in services. The airline has confirmed it will work quickly to restore all systems.
United Airlines is set for a major system shutdown tomorrow, February 4, 2026, affecting travelers, including those heading to Canada, Brazil, Mexico, France, and Germany. The shutdown is for a tech upgrade to improve system efficiency.
Conclusion
