On June 3, 2025, American Airlines experienced a significant booking system outage, leaving customers unable to search for or reserve flights for several hours. The disruption began around 11:00 a.m. EST and lasted approximately four hours, primarily affecting users accessing the airline’s website and mobile app, especially those flying from major hubs like Dallas/Fort Worth International Airport (DFW).
Extent of the Disruption
During the outage, customers attempting to book flights or manage reservations were met with automated messages stating, “Our system is having trouble.” The airline’s call centers experienced a surge in wait times, reportedly exceeding two hours, as frustrated travelers sought assistance through phone support. Notably, the issue was isolated to American Airlines, with major competitors such as Delta Air Lines, United Airlines, and Southwest Airlines reporting no disruptions.
Cause of the Outage
American Airlines confirmed that the issue was due to a vendor-related systems failure. While the airline did not publicly identify the vendor or offer an estimated time for resolution, technicians were actively working on a fix. This incident brought to mind past outages triggered by third-party software failures, such as the July 2024 CrowdStrike incident, which resulted from a faulty Windows security update and caused massive operational impacts across the U.S. aviation industry. However, unlike that event, the June 3 outage appeared to be isolated and was resolved within a few hours.
Speculation on Vendor Involvement
Given American Airlines’ long-standing partnership with Sabre Corporation, which provides its SabreSonic Passenger Service System, speculation naturally turned toward Sabre. In April 2019, a similar outage tied to Sabre’s platform grounded the airline’s reservation, check-in, and boarding systems across multiple airports. That incident also impacted other Sabre clients like Alaska Airlines and JetBlue. However, neither carrier reported issues on June 3, suggesting that a different IT vendor may be responsible for the current outage. American Airlines has not confirmed the identity of the affected vendor as of publication.
Recovery and Customer Guidance
By mid-afternoon on June 3, the airline’s systems were gradually restored. Flight searches, booking functions, and user access resumed, though some platforms still experienced lag. Reports on DownDetector sharply declined, signaling that most services had been restored. Affected customers are advised to monitor the airline’s official channels for updates. Passengers experiencing residual issues may be eligible for fare adjustments or travel credits. Experts recommend documenting attempted transactions, failed logins, and delays to support any refund or compensation requests.
