Cathay Pacific will offer PCCW's Netvigator e-mail service on all flights by the end of the year. The service will be offered on a free trial basis, from now until June, to passengers on 42 Cathay Pacific aircraft, more than half of the airline's fleet. The entire fleet would be equipped with the service by the end of the year, Cathay Pacific spokesman Patrick Garrett said. The service enables passengers in first class and business class cabins, and the front rows in economy class, to send and receive e-mail messages using their laptops. Some Cathay Pacific flights already offer an e-mail service provided by Tenzing Communications. Cathay's in-flight e-mail services uses the Tenzing network, which sends and receives information in blocks of 10 to 15 minutes. Tenzing's network competes mainly with a more costly service from Boeing called Connexion, which offers real-time broadband Internet access. Satellite communications provider Inmarsat offers a competing service called Swift64, which gives in-flight access to Internet-based applications such as e-mail, video streaming and file transfer at 64 kilobits per second. Several carriers have introduced e-mail access on long-haul flights following requests by passengers for the service. Singapore Airlines, Lufthansa and British Airways offer in-flight e-mail on selected routes, but Cathay is the first carrier to roll out the service across its entire fleet. Passengers can register online either on the flight or before at inflight.netvigator.com. Netvigator users are pre-registered for the service. After the free trial period, Cathay will charge for the Netvigator e-mail service. The basic package offers viewing of incoming e-mail headers at US$9.95 per flight. Sending or retrieving e-mail and file attachments costs 60 US cents per kilobyte. Customers can select to view the details of important messages only. Netvigator customers will enjoy special, lower rates for the same service.
