The shooter had barricaded himself inside an apartment building in the Bankers Hill neighborhood, firing a long-range rifle. According to FAA spokesman Ian Gregor, the apartment complex's location directly beneath the airport's approach path, in the 2400 block of Brant Street, led to a "full ground stop" being implemented.
San Diego International is the only major US airport with only one active runway, so delays were expected to be substantial.
"Due to police activity near the airport, a ground stop is in effect for all arriving aircraft. Check with your airline before coming to SAN," the airport said in a statement.
