Hi! If you’re flying with Spirit Airlines from Baltimore/Washington International Thurgood Marshall Airport (BWI), expect an affordable, no-frills experience. Spirit Airlines BWI Terminal operates from Concourse D in Terminal 1, handling both arrivals and departures. Check-in is smooth if you check in online and prepay for bags, avoiding counter lines. Security is generally efficient, but arriving 2 hours early is wise. Inside Concourse D, food, shops, and charging stations are found with limited seating. Terminal 1 is where your baggage claim is located, and taking a taxi, ride-share, or public transit are all easily accessed. Spirit Airlines is basic, yet it offers budget-conscious travel if you prepare in advance. Safe travels!
