SAN FRANCISCO — A major credit agency placed San Francisco International Airport on its “negative” outlook list Monday in anticipation of steep declines in passenger volume amid widespread anxiety raised by the Sept. 11 terrorist attacks. 

Fitch Inc. predicted the San Francisco airport will suffer a 25 percent drop in domestic passengers and a 15 percent decline in international traffic for the remainder of the fiscal year ending June 30. 

The agency expects the downturn and increased security costs to saddle the airport with a $100 million budget shortfall that will force management to slash expenses, lobby for money from the federal government and possibly raise its fees. 

Airport officials didn’t immediately return calls Monday. 

Fitch’s decision to change the San Francisco airport’s credit outlook from “evolving” to “negative” doesn’t immediately affect its bond rating, which remains at “AA-.” 

Fitch also issued negative warnings on several other major airports, including: St. Louis, Detroit, Philadelphia, Cincinnati, Memphis, Tenn. and Charlotte, N.C. 

All are suffering from the aftershocks of the Sept. 11 attacks, but the San Francisco airport is facing additional pressures caused by the technology industry downturn, which already had cut into business travel, according to Fitch. 

The San Francisco airport also is facing intense competition from nearby airports in Oakland and San Jose, where discount carrier Southwest Airlines operates its regional hubs, said Fitch analyst Jessica Soltz. 

Fitch hasn’t changed its outlook on the San Jose and Oakland airports.
