Interview was fast and my luggage was waiting for me. I’ll likely get it reimbursed again 5 years from now through CCs, but not sure I’d ever pay for it out of pocket. The MPC line was pretty fast, and the 30m I waited is probably more than all the MPC wait time for at least a couple years worth of travel for me (I don’t fly often).
It's $85 for PreCheck and $120 for Global Entry (which includes PreCheck). An extra $35 every five years is a small price, even if you don't travel internationally that often. For example, you might be coming into a U.S. airport from abroad, and connecting to a domestic flight. Saving time at immigration might be the difference of making or missing your domestic connection.
