I don't get the people mentioning about reduction in T&Cs etc as a possible reason for doing this. It may put a huge financial strain on his life, who knows, but it is no excuse to take 149 innocent souls with you and leave a permanent wake of despair with his family and friends for their lifetimes. Harsh but there are other ways of doing it solo.
Post 9/11 procedures have brought along their own unique set of problems and I am still amazed how the FFPO program got passed when you look at the tragic consequences of the Germanwings event.
