It was in fact a DC-10 as LoneStar says.
Either United or Continental, definitely one of the two, hard to tell which when you look at the cheat line because the picture is black and white and you see no logo no tail no title. Remember, at that time Continental also had a three color cheat line on a white fuselage.
But I would rather guess United for two reasons:
1. United always had a hub in San Francisco, not Continental, so they were probably the ones to transport the SF
2. When you observe the font of the word "Liner" above the cheat line, it looks similar to the font United was using during the Saul Bass rainbow color scheme era (mid 70s-early 90s).
