Still on the early side to tell if the changes are leading to less crowding, but my (admittedly limited) experience has been mixed.
ATL Terminal E last Tuesday afternoon was steady but not slammed.
LAX T3 last Thursday morning (around 8 am) was pretty busy.
DTW B/C concourse late Thursday afternoon was nearly empty: I'd be surprised if there were more than a dozen people there. Glorious!
DTW North? (by Gate 68) this morning around 8 was near capacity.
