Ahwile back, I asked to short check a bag on a SFO/LAX/XXX (int'l) trip - not on UA. The check-in agent told me that the computer was trying to SSSS me because of this. Once again, I have a similar trip (SFO/LAX/XXX) with a long LAX connection to another terminal, but with segment one on UA. Any potential problems/issues like in the past?
