Now being a social influencer can get you into airport lounges

American Airlines has rolled out a new perk for social media users, use of their Admirals Club lounges, regardless whether you are flying with them or not.

To gain a one-day pass for the club, you need to have a Klout score of 55. What does this mean? Klout is a tool that measures your usage and engagement on social media, including Facebook, Twitter, Instagram and LinkedIn.

The perk includes almost 40 lounges across the world including airports in San Francisco, Dallas, Los Angeles, New York, Tokyo and London.

With others already signed up to Klout Perks including Sony, Nike, Microsoft, Disney, Audi and Gilt, this is a major push by the social measurement tool.

A clever development, but one can't help to think that social influencers may see through it, regardless of whether they take advantage of it or not.
