Showing the first 40 of 65 scheduled IAH to SAT departures across 7 days with service, starting October 23, 2026. Every remaining date is on the interactive map.
Departure and arrival times are local at their own airport, so an arrival can fall on a different local date than the departure; the duration column is the true elapsed flying time. A dash means the airline hasn't filed that value in the schedule data we hold. Aircraft are the equipment the airline filed, named where the code pins down one type and shown as the family or the bare code where it doesn't. Swaps can happen up to departure.
