I'm seeing around 1 to 1.5 more hours of operation on Mavericks on a 2012 Macbook Air 11". Now, that is not for web browsing but for development & debugging with Xcode, so I'm usually never reaching these marvellous 6+ hour rates, but with Mavericks it went basically from 3-4 hours to 4-6 hours, which is fantastic.
I'm pretty sure that that will only widen the gap between OSX and Windows on Laptop hardware.
The 13" Macbook Air could then theoretically reach 17 hours of operation time!
