Oakland Airport is getting around to beginning planning of overdue terminal modernization/expansion. Details a little scarce at the moment but environmental studies are going to be starting soon with a project scope that presumably will include a new Terminal 0 and at least a modernized Terminal 1. On one hand new terminal capacity will not needed anytime soon, but they're eyeing 2025-2030 for construction, so who knows by then.
