United Airlines grounds mainline flights amid tech glitch
Hundreds of departures delayed; key hubs affected across the US.
An unexpected technical issue led United Airlines to temporarily ground all its mainline flights across key US airports. The disruption affected hundreds of departures, notably at hubs like Newark, San Francisco and Denver.
United Express flights remained unaffected, and in‑air services continued as planned. The airline reassured customers that safety was the top priority while staff worked to restore systems.
So far around 827 flights have been delayed and 23 cancelled. United confirmed that a cyberattack was not to blame for the outage.
Passengers reported delayed departures due to missing system data needed for take‑off. The airline noted delays may persist into the evening as technical fixes are completed
