So HA is guaranteed to keep a slot, but the nighttime one. This does not say they get the second they asked for. As of now it just shifts some traffic around the islands.
I would guess that the UA is a solid bet for their EWR proposal, and AA/DL neck and neck for the last slot (assuming the current LAX/LAX/SFO slots are kept).
It also is obvious why DL has MSP over ATL. the HND traffic will be O/D Tokyo. And as such will likely not be O/D either ATL or MSP. But MSP is a better connection for most of the east half of the US.The only advantage ATL would have is Atlanta<>Tokyo traffic, which probably does not move the needle.
