Showing the first 40 of 44 scheduled SAL to IAD departures across the next 7 days with service. 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 has not filed that value in the schedule data we hold. Aircraft are IATA equipment codes as filed, and can change up to departure.
