How have the TSA checkpoint lines been lately? Flying from DFW to LAS middle of next month. My mother does case management for TSA employees nationwide and has been telling me horror stories from "inside" saying how long the lines are and how they are way understaffed etc... But, she's been known to exaggerate a bit. So, has anyone been experiencing longer than usual wait times when getting to the airport? Wondering how early we should get there beyond the standard 90 minute rule. Last we flew it was Feb and the lines were fine. TIA!
