Stansted Airport has one terminal which sees over 27 million passengers fly to multiple destinations each year. | All passenger flights are served by this terminal. | The terminal houses 10 check-in desks, modern baggage and flight information systems and a wide range of shops, restaurants and bars.

London Stansted Airport (STN) is unique among major London hubs because it has only one main passenger terminal. However, this single terminal is connected to three separate satellite buildings that house the actual departure gates. In 2026, all passengers check in and pass through security in the same central building. After security, you either walk to Satellite 3 (gates 1–39) or take the automated track transit system (shuttle train) to Satellite 1 (gates 1–19) or Satellite 2 (gates 20–39). While it is technically "one terminal," the layout can be deceptive; a high-value tip for 2026 travelers is to allow at least 20 minutes to reach the farthest gates in Satellite 2 after finishing your duty-free shopping. Because Stansted is a primary hub for low-cost carriers like Ryanair and Jet2, the single-terminal design is intended to streamline high volumes of travelers, though it can become quite congested during peak morning and evening "bank" hours.
