Spirit Airlines DWC Terminal is based in Washington Dulles International Airport (IAD) Terminal A, not “DWC” (which could be Dubai World Central). In addition to domestic flights, Terminal A handles some foreign flights. Spirit has cheap flights, but there are fees for onboard amenities, baggage, and seat preference. Travelers should anticipate a simple experience with few eating options and self-check-in kiosks. Essential facilities including free Wi-Fi, resting places, and restrooms are available at the station. Shuttle services, rented automobiles, and taxis are examples of ground transportation choices. Prepare for possible extra expenses and security measures in advance for a seamless experience.
