I saw this idea in the US and wondered if it might work in the increasingly traffic-clogged UK.

Beacon is a service operating 15-20 flights a day between New York and Boston. For a monthly subscription of $2,000, customers can take as many flights as they  like between the two cities. The company have plans to extend the service to include holiday destinations Nantucket and The Hamptons. The owners have previously operated a similar service connecting Californian locations. They don’t own any planes, but rather, partner with other companies. Like any subscription based business of this type, the success will depend on some customers not using the service too regularly.

So would a subscription service linking London with Manchester, Edinburgh or a holiday destination like Cornwall find a market?
