Finally got some miles logged on the CX-9 and have gone through two tanks of gas. Survey says....

Mostly city driving: 17.8 MPG
Highway (AC on, full of stuff, 75 MPH): 25.2 MPG

That is pretty impressive. Our CRV does only marginally better.

 

I did some calculating since I just got my CX-9 a few weeks ago and I seem to be on par with where you are with the mpgs. It's not bad considering how big the CX-9 is.
