Why ORD gets delayed
O'Hare saw 243 FAA programs in the 12 months to October 2026, on 99 days: 164 ground stops and 79 ground delay programs. Chicago gets it in every season. Thunderstorms caused 55% of programs, snow and ice another 10%, and controller staffing 16%, a large share for an airport this size.
The storms that hit O'Hare are often long lines crossing the Midwest, and the programs reflect that. A typical ORD ground delay program ran 5 h 35 min with an average delay of about an hour and a half. The worst day of the year was April 2, 2026, when a thunderstorm program ran 18 h 26 min, and snow produced three programs of more than 14 hours in November and December 2025.
O'Hare's airline record reflects all of this: 72.6% of departures were on time in BTS data, among the lowest of the big hubs.
Written by the ATIS Alerts team from FAA Command Center advisories (October 2025 to October 2026), BTS airline on-time data (June 2025 to May 2026) and 20 years of hourly weather observations. Updated October 2026.
