If you are flying out of Reagan National, plan ahead. DCA Security Wait Times are often highest during early morning departures and late afternoon flights. Weekdays, especially Mondays and Fridays, tend to be more crowded due to business travel. Arriving at least two hours before your flight gives you a comfortable buffer. Midweek midday flights usually offer shorter lines and a smoother experience. Keep your ID ready, pack smart, and check live wait updates before heading out. A little preparation helps you move through security confidently and start your trip without unnecessary stress or rushing.
