Why SLC gets delayed
Salt Lake City was the most punctual of the FAA's 30 busiest airports in BTS data: 84.6% of departures left on time, with an average departure delay of 11 minutes. The FAA ran just seven programs for SLC in the 12 months to October 2026, all of them short, the longest under two hours.
The weather that does cause trouble is winter. December and January have the most instrument conditions in the 20-year record, about 10% to 11% of hours, when valley fog and low clouds settle in under the Wasatch Front inversions. Summer thunderstorms caused two of the year's seven programs.
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.
