I regularly transit Beijing Capital International Airport for domestic flights. The building complex is impressive compared to its international peers. However it provides a poor service that does not consummate its mega structure. The most pain is that one has to take a shuttle bus to change terminal. It is not easy to carry luggage on and off a crowded bus. The second problem is the poor working attitude of airport staffs. There has been a very significant drop in service quality since 2008 Beijing Olympics games. Immigration and security officers nowadays are usually impatient. Instead of helping a struglling tourist at the security checking gate, I have been scolded by them for small issues such as not stacking items neatly on the tray and not following the regulations printed on the wall. Even with 3 and 5 year old kids, my family was denied of using special immigration checkin passage. One staff told us that since they could walk, we should queue as everyone else. There are very limited choices of foods in the airport and the priced are jacked up too much. Toilets always have strong cigarette smoke.
