It's also worth noting that any current or previous airside connections (including the T3-IntlG bridge and the T1B shuttle) were solely to accomodate UA (and indirectly *A, although SFO didn't do AC any favors by placing them in International A for years.)
Just because 2 airlines aren't in an alliance doesn't mean that there aren't interline / joint ticketing agreements. I'd be surprised if UA and the other T-3 / Int'l G carriers didn't receive a modest amount of feed to its international flights from AA and VX. When I look for SFO/LAX/South America on LAN, I'm typically offered UA/AA/VX connecting options (maybe DL too).
