Just read this article and wanted to share it with you http://www.economist.com/blogs/gulliver/2013/09/korean-air?fsrc=scn/fb/wl/bl/czechmates . It is about the strategic partnership between Korean Air and CZA as well as the role of PRG as an alternative to larger hubs in Europe.
Thanks for sharing the article - it's an interesting idea and I hope it works for them.
