I'm surprised there's mention of OAK-EWR.

CO failed at this one years ago.

UA pulled out COMPLETELY from OAK

AA is pulling out of OAK-DFW (one of the first routes to go with the MAX issues)

Even Norwegian has moved some flights from OAK to SFO.

I suppose anything might work, but it certainly is a troubled market. The only way I could see AS trying to make it work is with a redeye out and morning flight back (basically use a Hawaii plane and squeeze that in overnight to get better utilization).
