United schedules overnight 2–3 hour SHARES outage; pre-cancels most departures
United will take its SHARES reservation platform offline for a controlled overnight restart next week, a planned 2–3 hour outage that will freeze bookings, ticketing, schedule retrieval, refunds and check‑in across web, app, kiosks, call centers and agency channels; the carrier has pre‑canceled most departures during the window.
