Disrupted: Commercial airlines

Air taxis - tiny, short-hop planes that are so affordable that business fliers can charter them whenever they want - are taking off. Virgin Charter, majority-owned by Richard Branson, aims to be the Expedia for this new market. By creating a portal that connects travelers to charter operators, most of whom are mom-and-pop shops, the company plans to bring more revenue into the industry, reduce the cost of operating air charter services, and waste less jet fuel.
