Airport officials said a report released by the San Francisco city controller’s office in July found that SFO, which has experienced six straight years of growth, had the highest passenger traffic growth among similar-sized airports across the country.

SFO had the highest rate of growth in passenger boardings from 2007 to 2014 at 33 percent, during a period when five other similar airports reported reductions in boardings, the report found.

San Francisco International reached its last major passenger traffic milestone of 40 million passengers in 1997, before the addition of the new International
Terminal, the BART extension to the airport, and the AirTrain light-rail system, as well as the renovation and reopening of Terminal 2, airport, officials said.
