Japan Airlines has signed up with Boeing in-flight Internet service on flights between Tokyo and New York - the first time the service will be available for trans-Pacific travel.

The Connexion by Boeing service will be initially available on alternate days, with the service becoming available daily by the end of June, according to a spokesman for the airline.

Connexion is a satellite-delivered data service that enables airline passengers to access the Internet via wireless LAN-compatible PCs.

The connection speed is typically about 5Mbit/s downstream and 1Mbit/s upstream. It supports e-mail, Web browsing, and corporate network access via a VPN.

Access will be available throughout the aircraft and cost $29.95 for the whole flight, or for $9.95 for the first 30 minutes and 25 cents for each additional minute. A $10 discount will be available until 15 July.

"We will gradually be expanding the service to more of our major business routes, but we haven't got a fixed timetable yet," the spokesman said.

Connexion by Boeing entered commercial service in May 2004 when Lufthansa began offering it on flights between Europe and the US. It is increasingly available from Asian airlines. All Nippon Airways began offering the service on flights between Tokyo and Shanghai in November. The airline plans to extend the service to its Tokyo-Los Angeles and Tokyo-New York routes, according to Boeing. Singapore Airlines Ltd. will start services on some routes during the middle of this year.

Boeing has also signed deals with Taiwan's China Airlines, and with South Korea's Asiana Airlines and Korean Air.
