Why SAT gets delayed
San Antonio is one of the steadier big Texas airports: 81.8% of departures on time in BTS data, better than Dallas, Houston or Austin. The FAA held SAT traffic on just 10 days in the 12 months to October 2026, mostly for traffic volume in June 2026 and a few thunderstorm stops.
The longest was a 4 h 13 min thunderstorm stop on October 1, 2026, the same day storms produced long programs at DFW, Love Field and Austin.
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.
