Transit Visa for Bejing China

Even though the airlines database (IATA) shows no visa needed to transit at PEK airport, it is incorrect. Apparently, customs was very courteous and let me know that there was a tit-for-tat policy in place, where US travelers are required to get a travel visa just to transit at Beijing Airport.

After some pleading and showing of my boarding pass for my next flight 13 hours later, they gave me a stamp for a 24 hour stay in my passport.

Moral of the story, be courteous and understanding of policy and the possibly politics between the US and China. Have all your supporting documentation, such as boarding pass/ticket for the connecting flight, etc... A visa will be required, but it may be issued at the discretion of the customs officials.
