(DALLAS, TEXAS) The Federal Aviation Administration said a chain of “multiple failures” in core air traffic technology triggered a major disruption at Dallas-Fort Worth International Airport and Dallas Love Field, stalling flights, stranding tens of thousands of travelers, and prompting a nationwide safety review. The outage began around 4:30 AM Central Time on September 17, 2025, and lasted about seven hours, with normal operations gradually resuming by 11:30 AM.
By day’s end, DFW recorded more than 420 delays and 97 cancellations, while Love Field logged 112 delays and 21 cancellations, according to airport and airline tallies.

What the FAA says happened
FAA Administrator Michael Whitaker said on September 18 that the breakdown began with a failed software update to the En Route Automation Modernization (ERAM) system — the backbone tool controllers use to see and guide aircraft across large sections of airspace. The sequence of events included:
- The ERAM software update apparently failed to load correctly.
- The backup system also malfunctioned, so it could not carry the load.
- A network switch failure further hampered recovery, creating a cascading effect.
With both primary and backup systems compromised, the FAA placed Dallas-area facilities on manual procedures, which slows flight flow to ensure safety.
The FAA ordered an emergency review the same day and directed airports and facilities to check both primary and backup systems. It also implemented temporary manual tracking and radio protocols for 36 hours at the two Dallas airports while teams validated equipment and data flows.
By September 19, the FAA issued Order 2025-09-19A, instructing all major airports and facilities to complete immediate audits of air traffic control technology and backup systems by October 15. The Department of Transportation announced an extra $250 million for urgent upgrades, and DOT Secretary Pete Buttigieg said federal oversight would increase until audits finish and fixes are verified. As of September 20, 27 major airports reported minor backup vulnerabilities during the mandated checks, according to the agency.
This outage recalls the January 2023 nationwide NOTAM (Notice to Air Missions) database incident. While the systems differ, both events point to pressure points in the national airspace system. The FAA’s NextGen modernization program has been ongoing for years, but 2024 audits flagged persistent weak spots in backup paths and failover procedures — areas now under close scrutiny after Dallas.
Scale and economic impacts
The disruption’s scale was striking:
- Early FAA estimates: ~63,000 passengers affected at DFW, ~14,000 at Love Field.
- Airlines reported an initial revenue hit approaching $18 million.
- Airport concessions and services at the two facilities saw roughly $4.2 million in lost sales.
These figures do not include ripple effects at connecting hubs or costs tied to crew displacement and aircraft rotations.
Airlines and unions reacted quickly:
- American Airlines CEO Robert Isom urged “accelerated” upgrades and redundancy across FAA systems.
- Southwest Airlines COO Andrew Watterson called for deeper collaboration and more transparency between carriers and federal officials.
- The National Air Traffic Controllers Association (NATCA) said the event revealed “systemic vulnerabilities” and stressed the need for staffing and training to match growing traffic and complex technology.
The episode highlights that redundancy must be true redundancy — not a single backup that can fail the same way the primary system does.
Impact on travelers — immediate guidance
For travelers — especially international students, workers, and family visitors passing through Dallas — the outage caused missed connections, overnight stays, and visa clock concerns. While immigration status does not change because of airline delays, longer trips can affect planned check-ins, grace periods, or class start dates.
If your journey was disrupted, take these steps:
- Keep documentation
- Save boarding passes, delay notices, and any airline messages.
- These records help schools, employers, or programs confirm the delay.
- Notify institutions quickly
- Students, workers, and exchange visitors (e.g., F-1, J-1, H-1B) should email their designated school official or HR contact if a missed connection changes arrival timing or reporting dates.
- Ask airlines about waivers
- Airlines said they would waive change fees for affected flights through September 25, 2025.
- Seek meal or hotel support
- For overnight delays, ask at the gate or customer service desk about vouchers; policies vary by carrier and cause.

Additional traveler considerations
- Visa/time-sensitive travelers: For students with I-20 reporting windows or workers with onboarding dates, a simple email and proof of delay usually resolves timing questions. If visa validity is near expiry, contact your school advisor or employer immediately.
- Customs and Border Protection (CBP): When arrivals bunch up at hubs like DFW, CBP may adjust staffing to match shifting arrival banks. Long lines can form when multiple wide-body flights land close together.
- Airlines’ duty-of-care: U.S. carriers generally do not offer cash compensation for delays caused by air traffic control issues, but they often help with rebooking, and sometimes provide hotel nights for overnight delays.
- Special needs and families: If traveling with children, older adults, or as a first-time visitor, ask about priority standby lists and seat protection on the next flight.
Policy and industry responses
Experts and stakeholders emphasize stronger redundancy, realistic drills, and workforce readiness:
- Dr. Susan Patel (MITRE) said the national airspace needs “resilient, redundant systems” to withstand combined software and hardware shocks.
- John McCarthy (Brookings Institution) urged funding to focus on layered backups and drills that stress test failover under realistic conditions.
The FAA’s nationwide review timeline:
– Full audit results expected by October 31, 2025.
– Additional upgrades scheduled into Q1 2026.
– Congress will hold hearings on October 10 to question officials about Dallas and broader hardening plans.
– Airlines and airports are forming a joint task force with the FAA to align upgrade schedules, share close-call data, and stress-test manual procedures.
On-the-ground operations and workforce impact
- DFW issued alerts asking passengers to arrive early and check airline apps for real-time gate and schedule updates.
- Love Field said it would keep extra staff at customer service desks while airlines clear the backlog.
- The FAA temporarily slowed departures during peak periods after the outage and then eased restrictions as systems stabilized.
For the aviation workforce, the event underscored ongoing strain:
– NATCA has warned that training pipelines and staffing levels must match system complexity.
– Manual tracking is safe but slower, requiring focus and teamwork across airspace sectors.
– The union is pressing for tools that fail gracefully and for regular recovery-practice drills.
Practical tips for international travelers connecting through Dallas
- Plan for fewer open dining options and longer ride-share waits if arrival is pushed late at night.
- If a connection goes past midnight, check how it affects hotel bookings or pickup plans.
- Keep proof of delays for school or employer reporting.
- Contact your institution or employer early if your admission period or visa stamp is close to expiring.
According to analysis by VisaVerge.com, hub disruptions at airports with significant international flows — like DFW — disproportionately affect travelers on study visas, work permits, or family-based entries. When flights bunch up, CBP staffing and inspection capacity can be strained.
Why this matters nationally
Although the Dallas episode was regionally centered, its consequences were nationwide. The United States depends on ERAM to keep traffic safe and flowing across vast airspace. A regional failure can ripple to other hubs through crew time limits and aircraft availability.
The FAA’s order to audit primary and backup systems signals the agency views this as a systems-level problem, not just a Dallas glitch. The central questions for policymakers and industry are:
- Will backups truly back up?
- Will software updates install safely across complex, live systems?
- Will controllers have the tools — and enough trained colleagues — to manage traffic if automation fails?
Congressional oversight, FAA audits, and DOT funding aim to answer those questions before the next major travel peaks.
Current guidance and next steps
- The FAA will publish more details as the investigation moves from preliminary findings to root-cause confirmation.
- DOT’s emergency $250 million will fund urgent fixes first and then feed into broader NextGen modernization.
- Airlines will continue to waive change fees related to the outage through September 25 and will add seats and larger aircraft where possible to move travelers.
For now, the FAA urges patience as teams complete audits and refine recovery plans. If you are still in Dallas:
- Keep checking your flight status and airline app.
- Talk to your carrier about standby options.
- Ask for meal or hotel support if needed.
- Notify school, employer, or program contacts early and keep delay records handy.
