The distance from Hertz in the southeast corner of the garage to B15 is a minimum of 4500'. With any queuing back and forth and lice navigation at speed it will get close to 5000'.

I was in TSA for less than 5 minutes with paid F, I stopped for a last bio and handwash, and bought a water. Hertz to B15 walking as fast as possible on the moving walkways with the longest kettle-dodging obstacle course in history was 27 minutes.

It's not the distance, it's the time. SLC has made the decision to achieve their cost savings at the expense of any visitors that choose to use a carrier other than DL, to the tune of a million hours a year.
