As far as marketing gurus are concerned airlines don't overtly market safety. Safety statistics are around if people want to look
I think you're missing my point, which is, I conceed probably off-topic and anecdotal. The fact is, however, and the commercial side of the industry does need to deal with this, there is a growing PERCEPTION (Which is not the same as technically proven fact) amongst the travelling public that the 777 is not safe and that 4 engined planes are safer.
Rationalize it as you will mate.
