Boeing on Thursday said it was considering the future of its Connexion in-flight Internet venture after six years of failing to turn a profit, but did not go as far as confirming a Wall Street Journal report claiming it was looking to sell or shut down the unit entirely.

The airplane manufacturer has reportedly spent $1 billion on the venture, which has seen low adoption rates among airline customers due to high costs and interest in alternate technology that relies on cellular signals rather than satellites. Internet usage on Connexion equipped planes has also been relatively low, leading Boeing officials to question whether frequent fliers even want the service.
