The company has introduced business class airfares and is actively targeting corporate clients – once the domain of Qantas and Qantas alone. Virgin plans to use its stake in Tiger to actively compete against Qantas' subsidiary, Jetstar, and the acquisition of Skywest is likely going to be targeted at Qantas Link, which operates predominantly regional and country air services. And the evidence appears that Virgin is gaining some traction, given the heavyweight airlines that have taken a stake in the company. Apart from Air New Zealand ( ASX: AIZ ), Virgin also boasts Singapore Airlines and Etihad as significant shareholders. Foolish takeaway Despite Virgin's proactive approach to grow its market share, airlines are notoriously bad businesses and we don't see the company as attractive. The great thing about the sharemarket is that you don't have to swing at every pitch. In Virgin's case, we'll just let it by and move on.
