>Does Lloyd's (Insurance) of London, or any other organization, have any secret ratings and ranking for many airlines around the world, based on risk factors, whether international carriers or domestic only?

Yes, that's only a portion of how they decide on what rates you will get. Of course if one airline has three crashes in a year most all airlines are sure to sustain higher (but not the highest) rates as well. Much more complicatesd then this, but I was interpreting what you might have been hinting at.
If one were to muse some more along these lines, would your inference be to punish the arline somehow by placing him in a "bad driver" category like with auto insurrance..
Don't forget the airline is mostly a user of equipment and the real owners are the folks like leassors and Boeing/Airbus who haven't been paid off as yet. Thus their liens against the equipment need carry insurrance as well.
Probably best to encourage flight safety in other ways
