My mileage matches yours almost exactly.

HWY, windows closed, no air, pre-ethanol = 24 mpg
HWY, windows closed, no air, 10% ethanol = 22.4 mpg
HWY, windows closed, air on, 10% ehtanol = 21.5 mpg
To my surprise my mileage is getting worse. I have nearly 10,000 miles and the only difference in my vehicle is ethanol. I'd read threads here and elsewhere claiming that ethanol offered reduced mileage but had no real proof. If appears that ethanol made my car 7% less fuel efficient. Interesting. Anyone else?
