Maybe for overland flights your odds fare better, but the statistics for transatlantic flights do not support your optimism. I know of no water crashes on commercial flights with any survivors.
Though the odds of a catastrophic event in commercial aircraft flying over the north Atlantic are highly unlikely, the outcome seems even more certain when such an event does occur. It doesn't seem to matter what plans get made. Once the crash in the water up there is inevitable, the outcome is pretty much going to be permanent.
