Overview

• United asked the FAA to halt its U.S. and Canada departures around 1 a.m. ET, and the ground stop was canceled roughly 30–60 minutes later.
• The airline said it experienced a brief connectivity issue just before midnight Central time and reported that normal operations have resumed.
• This was United’s second networkwide halt in about two months, after an Aug. 6 technology problem that caused widespread delays at major hubs.
• Early tracking snapshots indicated dozens of delays and a small number of cancellations, though the overall impact remains unclear.
• American Airlines reported separate technical issues affecting some maintenance applications and used alternative procedures that led to some delayed departures.
