I have had a few layovers at Beijing and sadly, each and every single time my experience has been negative. Very rude staff, whether you're at the passport control or at a coffee place. Terminal three is huge and I understand that it's not easy to heat it, but why use a/c when it's -2 degrees Celcius outside? Many shops close after 10 pm even though there are numerous international flights after that time. And last but not least, wifi is unbelievably unreliable... I'll try to book my flights with no layovers at Beijing from now on.
