Got to try out the new system of lines at SFO last month. It was pretty dysfunctional.
I walked up right as Group 2 was called. Except, since there is a single group 2-4 lane, when the GA called Group 2 no one knew what to do. Then it turned into a Southwest-esque scene of people in the line comparing boarding passes trying to figure out who should go first.
In the end, a BIS Gold lines up the same as a no-fee-first-year credit card holder. Never in my life have I felt so over-entitled. Sure glad UA is putting me in my place.
EDIT: Or apparently a BIS Platinum, too. Incredible.
