United Airlines tech outage causes flight cancellations, delays
Over 800 flights cancelled and hundreds delayed after a systemwide ground stop in the US, affecting international routes to India as well
More than 800 United Airlines flights were cancelled and hundreds more delayed by late Wednesday (August 6) following a major technology outage that forced a systemwide ground stop across the United States, severely disrupting both domestic and international travel.
At Houston's George Bush Intercontinental Airport (IAH), where United operates a key hub, long lines and frustrated passengers filled terminals. The airline traced the outage to failures in its dispatch and fuelling systems.
"Due to a technology issue, we are holding United mainline flights at their departure airports," United said in a statement. "We expect additional flight delays this evening as we work through this issue."
FAA confirmation
The Federal Aviation Administration (FAA) confirmed that the grounding was initiated by United and shared an official statement on social media: "United Airlines requested the FAA to pause its departures nationwide while they addressed a technology issue. The FAA is monitoring the situation closely." Among those affected was Ishya, a young professional from New York scheduled to return to LaGuardia Airport after a brief family visit in Houston.

The outage affected United's global network as well. Flights from Newark and Chicago to Delhi and Mumbai were delayed by several hours, complicating onward connections for passengers from cities including Houston. Routes to Frankfurt, London, Sao Paulo and Panama City also faced cascading delays.
United encouraged customers to monitor flight updates on its app or website and to consider rebooking or applying for travel waivers.
United apologises
"We apologise for the disruption and thank customers for their patience," the airline said in a social media post.
While the FAA lifted ground stops at hubs like Houston by late Wednesday evening, aviation analysts warned that residual delays could persist into Thursday, especially impacting long-haul and international flights requiring tight connections.
Passengers travelling internationally were advised to confirm onward flights even if US departures had resumed.
