Boeing is killing its in-flight Internet access service Connexion, leaving what it once considered a promising market.

"Regrettably, the market for this service has not materialized as had been expected," said Boeing head Jim McNerney. The company will run through an orderly phase-out, the company said.

Connexion offers broadband Internet access via Wi-Fi, using a satellite connection to the Internet, that costs about $10 to $30 per flight on commercial airlines. It also offers high-speed Internet access on executive jets and ships.

Connexion is offered on some commercial flights in Europe and Asia but was never adopted by a major US carrier. First conceived in 2000, the service was approved by the US Federal Aviation Administration in May 2002 as the nation's airlines were reeling from a travel slump that followed the 11 September 2001 attacks.
