When you search for flights to China's capital, you'll often run into the code BJS. This isn't a specific runway or terminal. Instead, Beijing airport code BJS serves as the metropolitan area identifier covering all commercial aviation hubs serving the city. If you're booking an itinerary, seeing this code means your flight could land at either major facility depending on the airline and route.
Understanding how this multi-airport system operates saves you from costly transit mistakes. Beijing handles massive international and domestic passenger volumes through separate mega-complexes positioned on opposite sides of the urban center. Knowing which terminal you're arriving at prevents last-minute taxi confusion or missed connections. Let's break down how the code works, what the individual airports are, and how you can navigate China's premier aviation gateway without a hitch.
Decoding BJS: Metropolitan Area Codes Explained
The International Air Transport Association assigns three-letter identifiers to cities with multiple airports to simplify ticket booking. When a travel agency or aggregator displays BJS, it acts as a catch-all umbrella. You won't actually see BJS painted on baggage tags or boarding passes for specific physical flights. Instead, your tickets will show either PEK or PKX.
This system helps when you're flexible on routing. If you search flights using the metropolitan identifier, you cast a wider net to compare fares across all available carriers. Once you complete the purchase, the airline assigns the exact physical airport. Double-check that assignment immediately. Driving from one side of Beijing to the other can take well over an hour, so showing up at the wrong facility ruins travel schedules. Lonely Planet has analyzed this important subject in extensive detail.
The Two Major Airports Behind the Code
China built a second massive aviation hub to handle growing international demand, transforming the city into a dual-hub metropolis. Each facility has distinct characteristics, distinct terminal layouts, and distinct transit connections.
Beijing Capital International Airport (PEK)
Located about 30 kilometers northeast of downtown, Beijing Capital International Airport is the older and more established primary gateway. It features three large terminals, with Terminal 3 serving as one of the largest airport terminal buildings in the world.
- Primary Users: Air China uses PEK as its main operational base, alongside many Star Alliance international carriers.
- Layout: Terminals 1 and 2 sit close together, while Terminal 3 sits further east and requires a dedicated internal shuttle train for transit between its sub-sections (T3A, T3B, and T3C).
- Vibe: Highly efficient, deeply integrated into older business corridors, and heavily trafficked by legacy global airlines.
Beijing Daxing International Airport (PKX)
Opened in late 2019, Beijing Daxing International Airport sits 46 kilometers south of Tiananmen Square. Designed by the late architect Zaha Hadid, the starfish-shaped terminal structure aims to minimize walking distances from the central security checkpoint to the furthest boarding gates.
- Primary Users: China Southern Airlines and China Eastern Airlines anchor operations here, alongside various SkyTeam and Oneworld partners.
- Layout: A single, massive radial terminal design allows passengers to reach any gate from the center within roughly eight minutes of walking.
- Vibe: Ultra-modern, spacious, packed with high-tech biometric check-in kiosks, and featuring striking architectural aesthetics.
Ground Transportation and Transit Links
Moving between these airports and the city center requires understanding local rail and road networks. You won't want to rely on standard street cabs during rush hour unless you enjoy sitting in gridlock.
The Capital Airport Express rail line connects PEK Terminal 2 and Terminal 3 directly to Dongzhimen and Sanyuanqiao stations in the city center, taking about 20 minutes. For Daxing, the Daxing Airport Express train runs from Caoqiao station straight to the terminal basement in roughly 19 minutes, hitting high speeds along the route.
If you take a taxi, always use the official designated queue lanes outside the arrival halls. Refuse offers from unlicensed drivers lingering near the baggage claim exits. Keep your destination address written down in Chinese characters, as many drivers don't speak English. For more details on local transport options, check the official Beijing Municipal Culture and Tourism Bureau portal.
Navigating Custom Regulations and Transit Visas
Arriving at either facility under the Beijing airport code BJS umbrella means clearing customs and immigration under national Chinese border policies. Travelers often utilize China's 144-hour visa-free transit program if they are flying from an eligible country to a third destination.
To qualify for the transit exemption, you must hold a confirmed onward ticket to a third country or region within 144 hours, along with a valid passport. Fill out the temporary entry cards distributed near the immigration desks before joining the queue. Follow the specific lanes marked for 144-hour transit to avoid getting stuck in standard resident or long-term visa lines.
Common Mistakes to Avoid
Travelers frequently trip up on a few operational details when dealing with Beijing's dual-airport setup. Keep these pitfalls in mind to stay stress-free.
- Assuming proximity: Do not assume your connecting flight uses the same airport you landed at. If you change airlines on a self-transfer, you might need to commute between PEK in the northeast and PKX in the south. Allow at least four to five hours for airport-to-airport transfers.
- Ignoring luggage rules: Power banks must be carried in your cabin baggage with clear capacity markings. Security agents at both facilities confiscate unlabeled lithium batteries immediately.
- Relying on open web apps: Major Western mapping and communication tools do not function properly inside China without a reliable roaming plan or specialized setup. Download offline maps and translation apps before you depart.

Frequently Asked Questions
Is BJS a physical airport?
No. BJS is a metropolitan designator used by ticketing systems to represent all commercial airports serving Beijing collectively.
Can I walk between terminals at PEK?
You can walk between Terminals 1 and 2 via an enclosed walkway, but Terminal 3 requires a free terminal shuttle bus or the internal airport train system.
How much time do I need for a transfer between PEK and PKX?
You should budget a minimum of five hours. The distance between the two airports is substantial, and traffic on the ring roads can cause major delays.
Do I need a physical printout of my hotel reservation for immigration?
Yes. Chinese immigration officers frequently request a printed copy of your hotel booking or local host invitation letter during entry clearance.
