At the Boyd conference in September, I sat down with Trey Fayard, CEO of GLO, at the hotel bar. GLO is a regional air service provider based down in Louisiana.  It's flying turboprops as an independent regional.  This model hasn't worked very well elsewhere (with the possible exception of Silver in Florida), but Trey says things have grown nicely in the last year and profitability is coming shortly.  I have to say, it was a really interesting conversation that's well worth the listen.
