Airport Transit, Baggage Question at Beijing Airport.
Hi
I will transit in Beijing airport for 12 hours, overnight. I will come in from Detroit on Delta Airlines and on to the US via Miat airline the next afternoon. In Terminal 2 to Terminal 3.
I will not have a Chinese visa. I understand I can transit visa-free for 24 hours even as an American . The embassy website also says I cannot leave the airport.
But does this mean I can still proceed through customs and immigration, as long as I show the immigration officer my onward journey tickets? I ask this because I'm not sure how I can make sure my check-in baggage can stay with me. I assume I'll have to pick the bags up from my first airline (Delta), then check them in myself with my second airline (Miat). But, if I can't clear immigration (and onward to the baggage claim area), how would I accomplish this?
