ATL-SLC 162.50 on UA. They're doubtless skirmishing with DL.

Only downfall is a 2 day min. stay, although works ok for a weekend.

No routings through LAX/SFO, though.

I'm going
ATL-ORD-SLC on Fri 7/20
SLC-DEN-IAD-ATL on Sun 7/22

you can add segments essentially at will between DEN/ORD, DEN/IAD or ORD/IAD, according to the fare rules.
