But Baiyun airport's links to mainland market, and lower costs may cause concern
Chek Lap Kok will face the biggest challenge of its six-year history this week when Baiyun International Airport opens for business.
Baiyun is an impressive facility and the aim of its builders is to help Guangzhou compete squarely with Shanghai and Hong Kong as gateways for tourism and commerce into and out of the mainland.
The first phase, comprising two runways and a terminal building able to handle more than 25 million passengers a year and 1 million tonnes of cargo, will accept its first flights on Thursday. Developments over the next three to five years will allow it to double its capacity.
Like Chek Lap Kok, Baiyun's structure is modern and forward-looking. Visitors will be impressed by its scale, as well as the city and provincial governments' 20 billion yuan commitment.
The opening of Baiyun comes as the Hong Kong Airport Authority, which operates Chek Lap Kok, prepares for privatisation and a public listing on the stock exchange.
