As with most major Airports what time you arrive at BWI will depend on a number of factors including your airline, weather, seasonality and day of the week. Being the busiest airport serving the area, more so than nearby Washington Dulles & Reagan Airports means long security lines can occur relatively often. AS a general guide we would suggest you plan on arriving 3 hours before an international flight and 2 hours for a domestic flight.
