The opening of the post-security walkway is fantastic. I'm all for more ways to getting around any airport w/o having to leave security. I think this makes it possible to walk to every SFO terminal and concourse without leaving security. I am not sure the current state of terminal portion between the two Terminal 2 piers though with the construction. With TSA Pre, it may be faster and not that much hassle to leave security and re-enter though like the opposing international piers. This makes it great to be able to view the SFO artwork exhibitions that are scattered around if one has time to kill.

Interesting that United is T2 is being used by United now. Another departure location that one needs to pay attention to in the app before leaving.
