I'm flying CZ (China Southern) from KTM to SFO by way of CAN and have 6 hours in the CAN airport (arriving around 5:30am). The departure is a 787 to SFO. Some questions:
1)what concourse am I likely to arrive in and to leave from? The best CZ lounge appears to be in the No. 1 East corridor. Any information about the lounge appreciated.
2) Is it worth getting a Temporary Pass (allows 24 hrs stay in China) and leaving the airport? Reports online are mixed.
3) What is the best place to eat in the airport?

thanks
