This is a nicely thorough guide - but is this the most recent pattern or back from when the new LGA B opened?
For example, the precheck entrance has now changed. I
think the non-precheck priority line may be gone (I don't remember seeing it a few weeks ago), but I am not certain. Within that entrance I believe B-fast is on the left and everyone else was 1 lane on the right.
