I think ANA will move the HND-LAX flight to one of the new daytime slots, perhaps with late evening departures on both ends instead of midnight departures. Another slot will definitely be used for JFK. Third slot for either ORD or SFO (I expect UA would operate one of these routes from HND and NH would operate the other).

Note that a bunch of the midnight slots for US flights from HND are supposed to go away. There will supposedly only be two left, one for US carriers and one for Japanese carriers. I imagine that NH will give up HND-HNL and consolidate HNL service at NRT (which would explain the rumored A380s).
