Actually Cathay only started a trial based system.
When the service rolls out in the second quarter of 2001, Cathay Pacific will be among the world's first airline to offer passengers inflight email and Intranet services across its entire fleet. Tenzing will provide Cathay Pacific passengers with a suite of inflight services including the sending and receiving of emails and attachments, an onboard Intranet providing "Best of the Web" surfing, and e-Business services.
SIA has rolled out the service already. On one plane. However, CXA will be the first to install it all fleet-wide
Anyone can fly, only the best Soar.
