Security wait times at Charlotte Douglas International Airport (CLT) typically average between 15 and 25 minutes, but they can fluctuate wildly during "bank" periods when multiple flights depart simultaneously. During early morning peaks (4:00 AM – 7:00 AM) and mid-afternoon rushes (2:00 PM – 5:00 PM), standard wait times can easily climb to 45 minutes or more. CLT has undergone significant terminal expansions through 2025 and 2026 to improve passenger flow, but it remains one of the busiest hubs in the world. For travelers in 2026, the "Live Wait Times" feature on the CLT mobile app or website is highly accurate and should be checked before arriving. Having TSA PreCheck or CLEAR is a major advantage here, often reducing the wait to under 5 minutes even when the standard lines are wrapped around the atrium, making it a "must-have" for anyone frequently connecting through this major American Airlines hub.
