Well in the settings, apple separates between standby and usage. Right now I'm close to 15 hours with juice at 10%.
I certainly don't remember my ipad 4 having such stamina!
It does, actually. I just checked my 4 and it's at 65% battery after 12 hours usage and more than 3 days standby. The iPad 3, however, is pretty faithful to its specified battery life at around 9-10 hours, though.
Still, the Air's battery life is pretty impressive considering the 25% decrease in battery capacity.
Are you sure your battery is not running on nuclear power? If you have 12 hrs usage with 65% juice remaining, by the time you are at 0%, you will have had roughly 36 hours of mileage.

As stated, it did. I think my Air battery is still cycling in, but I've seen up to about 16-17 hours use so far. That was typical of my ipad 4 and I saw up to 25 hours IIRC. I'm sure some of that was screen off, but if it was still doing useful work (like music or Airplay) I'll take it.
The amazing thing is how much smaller the Air's battery is while pulling this off.
