Had to go through security again to switch terminals in San Francisco for this connecting flight. Confusing and inconvenient. Connecting boarding passes did not have TSA pre-check on them (only initial ticket did). Frustrating and difficult for one of our travelers to have to do.

Only bad thing was kid kicking seat and playing with the tray table for 1hr of the 2hr flight despite asking the parent to attend to their child.
