I am always take on Elite lines that I am Silver Eilte with DL. When I am fly out PHX from last 2 months ago when I am gotten in lines when I am go through checkpoint. I show TSA with BP & ID, too. I am always special lines when I am go express lines. I can see the sign to had say Silver, Gold, Summit or Crown Room here in terminal 3 at PHX. What is reasonable that I can allowed go through Elite lines but, it is not in general lines. it is too long when I was go through employees lines. This morning it is too crowding to trying get through checkpoint mid-morning when they are fly out from PHX in north concourse with gates 15-26. Does you know anybody else why security checkpoint is always busy during peak hour. Because here in Arizona does not have operating daylight saving time.
