With new Southwest Hawaii routes available this summer, pricing is shockingly low for flights there, as well, with San Diego to Honolulu (HNL) and Oakland, California, to HNL both starting at $139 each way. (But be aware that, even though Hawaii is ending testing requirements for vaccinated travelers, the state's COVID-19 requirements could make travel cumbersome.)
