Apparently there were lots of deals to Hawaii yesterday from west coast airports. Today I primarily see Oakland and San Jose have discount American Airlines flights to Honolulu HNL, Kahului OGG, Kona KOA at $295 round trip for departures in the second half of August through September.
There are more Hawaiian airports on sale with Lihue LIH and Maui OGG in the $320 to $360 range with carriers like Delta and Alaska.

Cheap AA flights mostly mean a red-eye back to California.
There is also the option of two one-way tickets with different airlines for more dates at low prices.
