Transit via Chinese Airports: how it works in any — first-hand
Short answer
For seamless transits with checked-through luggage, ensure you hold a single unified booking ticket. While 1.5 to 3 hours may suffice for airport connections, use official visa-free transit policies to explore the city during longer layovers if eligible, keeping in mind that lighters and sharp personal items are frequently confiscated.
From real experience
Transiting through China: If you have a single ticket with one airline or a unified booking number (especially with a 'no skipping flights' clause on platforms like Trip.com), you should receive two boarding passes and have your luggage checked through to your final destination.
This means no baggage claim or re-check-in in Beijing, only security screening and proceeding to your gate. Airlines are obligated to get you to your destination even with delays. Be aware that lighters are confiscated in Beijing. Korean authorities may confiscate small personal items like manicure sets, even if previously allowed; it's best to pack such items in checked luggage.

Transiting through Beijing Capital International Airport (PEK) with a 1.5-hour layover is possible if you remain within the same terminal and procedures are efficient.
However, be prepared for potential delays, especially during hand luggage checks. Some travelers report needing significant waiting time after transit procedures. Longer layovers (e.g., 23 hours) are recommended to minimize the risk of missing connecting flights.

If you remain within the transit area, no additional forms are needed. Failure to complete the form when required may result in being denied entry.
