SFO-CTU then CTU-SIN Do we have to change terminals at CTU
As senior travelers, we find that we enjoy a trip more if we have a pretty good idea of what we will have to deal with in airports that are new to us. We arrive Chengdu CTU at 6 a.m. on a Wednesday on a United flight from SFO. We depart for Singapore SIN at 9:55 a.m. on a Star Alliance Air China flight. We would like to know if we must leave the international terminal for any reason before boarding our flight to Singapore. We plan on having our luggage checked through from SFO to SIN. If we are able to stay in the same terminal for arrival and departure, do we have to pass through security again? Also, is food available in the international terminal or do we have to leave and return through security to obtain a meal? Finally, Air China has told us that we cannot get a seat assignment in advance. They will be assigned at check-in for the Singapore flight. Does this mean we must go to the main ticket counter? Or can we simply hang out near the departure gate? Thank you for any information you can provide.
