I used this twice today. Was a really nice added feature/benefit. Something I “will like”

TPE-SFO they had two really long lines when I got there they were calling 1k and I walked right on.

SFO-EWR with the new two line boarding area. I got there late due to a late connection and everyone was in the lane 1. I wondered to the front and asked the gate agent if they called 1k yet and she just had me merge into the line.
