Your luggage will go straight to ABZ, and you'll pick it up in the luggage shed outside the airport.

This is a ProTip, but only makes a difference if you go through the regular security to get to your domestic connection in the US, e.g., if you are landing at TBIT at LAX and then walking to T7 to catch a UA flight. I have never been through a dedicated post-immigration security station that had PreCheck. While you are landslide, you can also just hit a carry-on only kiosk to get the UA BP.
