Beijing Capital (PEK): The Complete Layover Guide

PEK runs on two working terminals, and the difference between them shapes your whole layover. T2 sits beside the old T1, which closed in 2020 and reopened in August 2023 as a satellite wing of T2 rather than a standalone terminal. T3, across the airfield, is where Air China and most Star Alliance carriers operate, and it handles the bulk of the international traffic that stayed at Capital after Beijing Daxing opened in 2019. SkyTeam carriers, including China Eastern and China Southern, moved south to Daxing, so if your ticket says PKX you are reading the wrong page.

T3 deserves respect. It was the largest passenger terminal building in the world when it opened ahead of the 2008 Olympics, stretching close to three kilometers from end to end, and it still swallows first time visitors. The building splits into three concourses: T3C holds check in and the domestic gates, T3D handles Air China domestic flights, and T3E takes every international departure plus Hong Kong, Macau and Taiwan. A driverless internal train links the concourses, and the ride itself takes only a few minutes. Add the escalators, the platform waits and the raw walking distance, though, and moving from the check in rows to a far T3E gate can eat 20 to 30 minutes without you doing anything wrong.

There is no airside connection between T2 and T3. Changing terminals means clearing immigration, collecting any bags that were not checked through, riding the free landside shuttle and starting over at security. The shuttle runs 24 hours, leaving from gates 7 to 9 on the T3 arrivals level and gate 7 at T2, every 10 minutes during the day and every 30 minutes between 23:00 and 06:00, with a ride of about 15 minutes. The airport publishes 120 minutes as the minimum connection time for an international to international transfer across terminals. Treat that as a floor, not a promise. Three hours is the number I would actually book.

Transit immigration is the part people underestimate. Even connecting passengers face document checks, and arriving foreigners record fingerprints at self service machines before joining the inspection queues. If you want to leave the airport, citizens of 55 countries can use China's 240 hour visa free transit policy, which since December 2024 allows up to 10 days in the country, provided you continue to a third country or region on a confirmed ticket. T3 immigration has a dedicated channel for transit permit applicants, and you complete a digital arrival card in advance through the National Immigration Administration site. Queue times swing hard with arrival banks, so give yourself a generous buffer at peak periods and verify the visa rules before travel.

The free wifi is real but earns its asterisk. The network is unlimited and reasonably quick, but you cannot simply tap and connect. You either receive a login code by SMS, useless without roaming, or you feed your passport into one of the self service kiosks scattered through the terminals, which scans the photo page and dispenses a code. Find the kiosk before you need it. And remember the connection sits behind China's internet filters: Google, Gmail, WhatsApp and most Western apps will not load unless you arrive with a VPN already installed or use international roaming data.

Overnight, the terminals stay open and nobody moves you along, but the building changes character. Most shops and counters close, the cleaning crews take over, and the air conditioning makes T3 genuinely cold after midnight; regulars bring a layer. The Airport Express train into the city is a 25 yuan ride that reaches Dongzhimen in about 25 minutes, but it stops mid evening, with the last city bound departure from T3 at 22:51 and service resuming at 06:21, so a late arrival means a taxi or a long wait. What surprises people most is the pace. Signage is good and staff are used to confused transit passengers, yet every process here assumes you have time, and rushing PEK almost never works.
