Security lines at Miami International Airport stayed manageable Tuesday with TSA wait times averaging under 15 minutes across most checkpoints, offering a bright spot for spring break travelers navigating the partial government shutdown that has snarled operations at many major U.S. hubs.
As of mid-morning on March 31, 2026, real-time data from the airport's website and third-party trackers showed general security waits ranging from 3 to 14 minutes depending on the checkpoint, with TSA PreCheck and Clear lanes often clearing in 1 to 5 minutes. Checkpoint 5, for example, reported general waits as low as 1-3 minutes, while Checkpoint 3 hovered around 10-14 minutes for standard lanes. Some priority and PreCheck options remained limited or closed at specific points, but overall flow remained far smoother than at hard-hit airports like Atlanta or Houston.
