IME, the LAX T4 AC has always been ridiculously crowded except late at night when it is creepy empty.
I’ve noticed most of the AC’s I use (as a member) are typically crowded (sometimes uncomfortably). LAX, SNA, PHX, AUS, ORD, SFO, LGA. Too many members and boarding pass guests for capacity.
They need to to make it more exclusive, more expensive or basically scale the footprint to handle the traffic.
