Grand scale, tiring distances
The soaring terminal is architecturally impressive and the internal train helps you cover ground.
It's a sprawling place and connections can involve a lot of walking plus a train ride.
Beijing Capital's main terminal is a monument in its own right, with those long sweeping ceilings. The size is a double-edged thing, though, because reaching your gate can be a trek even with the shuttle train. It functions well, but you'll clock plenty of steps getting through it.
