Free Wi-Fi in Hong Kong's Chek Lap Kok airport: The Internet provider PCCW launched service three years ago with fees attached, and only offered access in limited locations. The service in Hong Kong will now be throughout all terminals and areas, and be available at no cost. Service used to substantially more than their comparable service in the city. The company doesn't discuss what it gets out of going free in the article, but it's clear that it's a great promotion for them to have many more users seeing their name, and then buying other services from them--including more moderately priced Wi-Fi (HK$18 or US$2.30 per hour) at locations throughout Hong Kong.
