I've got a domestic to domestic connection at SFO going from AS to DL. AS appears to fly out of the A terminal whereas DL is out of the C terminal.

Is there a way to stay behind security or should I plan on having to clear security again at the D terminal? I've got 1hr 45m between connections so I'm not too worried about timing but trying to figure out the most efficient possible method to make the transfer between the two airlines.

Edit: Updated D terminal to C terminal because my googlefu is weak this morning
