ELI5: Airbus/Boeing Advertisements, Who are they trying to target?

the A350XWB just delivered to its first costumer today, 
this question just popped up in my head, 
I have seen Airbus and Boeing advertisements in airports, on the streets, magazines, youtube... promoting how efficient their products are and passenger comfort onboard, etc. 
It makes me wonder who are they trying to target? I doubt if any (most, at least) of us can afford one. It's airlines who make the purchase, and their job to promote their products. So, why are Aircraft manufacture like Airbus and Boeing spending millions on those advertisements seem to target the general public? Attract Investors? For public image? I wonder how many people care what kind of airplanes they are taking as long as it takes them from point A to B. 

it could also apply to many other things, not just airplanes.

They're trying to drum up public confidence.  It gets people to invest in shares.  Also, when you (and millions of others) book your next flight, you might choose an airline or flight that flies your preferred aircraft, rather than the airline that flies some other aircraft.  This signals the airlines to buy more of your preferred aircraft.
