Beijing Capital International Airport (PEK) is not served directly by Spirit Airlines PEK Terminal. You will probably need to utilize other airlines and PEK terminals for connections involving Spirit Airlines. There are three terminals at the airport: T1 (domestic), T2 (international), and T3 (the largest, which handles both international and local aircraft). Prepare to go through security and immigration checks and use the complimentary shuttle service to move between airports. For information on the precise terminal and connection, see your itinerary.
