"I have to respectfully disagree with the opinion that the elite/priority line at the South terminal is faster. At certain times of day, yes, but on Monday morning, the main checkpoint is generally faster due to more TSA agents checking ID and more lanes to choose from. I use the priority line during the off business travel times."
This Monday I waited longer in the priority line than the regular Southe terminal line right next to us. But, still it was less than 20 minutes.
