South China Morning Post – Anecdotal evidence of airport and airline delays abounds. But some solid data might surprise all but seasoned travellers. According to FlightStats, a popular US-based provider of data on air travel, Beijing and Shanghai rank at the bottom of 35 major international airports surveyed for flight delays and cancellations. And their performance has gone from bad to worse in the past six months. Hong Kong International Airport has also reported an increase in delays and cancellations that dragged its ranking down from 22 to 29.
