So some clarification if a visa is required or not would be greatly appreciated: DMK(BKK)-CAN-CTU-LAX I've only had a couple flights between 2 different airports in china, and the 2 times they just stamped me for 24hrs. So since I'm not the one flying I just want to make sure. I'm more of a oh well type of person, the flier is not lol. She'll be using a US passport as well. Flights arrive and depart on the same day as well.
