I do this flt 1-2x/mo, personally like the RJ 9. Last month because of the construction at LAS, the RJ flts were not going out of the 32-34 gates as usual. Instead they were something like gate 9-13 or so. In other words, up to the escalator and go to the left instead of the right. Was told it will go back to the old gates when the remodeling is finished.
As for the LAX gate, this really is a wild card. Sometimes it is T5, sometimes T6. Seems most often it is T5 (yay!) but sometimes not.
Really nothing special about the flt. Personally like seat 1A, kind of feels more like a private jet but it is a very short flt so a couple drinks and brief snack basket service is about it.
