My girlfriend and I are planning a trip to Thailand this winter (from the UK), and the cheapest option appears to be Air China, with a 6-hour layover in Beijing (PEK).
Given that neither of us can speak or read Chinese, will we be able to find our way around? Are the signs & displays repeated in English (or another language with Latin characters)? Are there plenty of multi-lingual staff? (both in the airport and the catering outlets)
Also, is 6 hours long enough to see anything of the city using the 72-hour visa-free transit option? or is it better to remain in the airport?
