The implementation Northern California Metroplex effort is complete. Expected long-term benefits include improved efficiency, increased access to affected airports, and improvements to operations. The project redesigned airspace, introduced new Performance Based Navigation (PBN) procedures, and made use of Time Based Flow Management (TBFM) to make the Northern California Metroplex airspace more efficient with improved access to its airports. Some of the airports in the focus area include Hayward Executive (HWD), Oakland International (OAK), Palo Alto Airport of Santa Clara County (PAO), San Francisco International (SFO), Norman Y. Mineta San Jose International (SJC), and Sacramento International (SMF). The information below may also include data from nearby airports outside of the Northern California Metroplex.

Northern California Metroplex benefits were negatively impacted by several factors. These factors included: New departures introduced shallower climb profiles which led to higher fuel burn estimates; fuel cost decreased approximately 50% between time periods; differences in aircraft payload; and, higher wind conditions during the period analyzed. Flight distance for San Francisco arrivals also increased slightly.
