I've read about BA's franchise with Sun Air, but it seems such a odd little airline to have as a franchise of the BA brand. You can understand Comair in South Africa -- it provides a good range of domestic services in ZA to places that BA passengers might well connect to, but why Sun Air? Their hub at Billund isn't exactly ideally located for anything except Legoland and Lego's headquarters. What's the point?

Does anyone here fly them, and how do they compare to BA mainline, or Comair flying as BA, or any other franchise (I can't think of any other current ones)?
