Direct answer: To gauge current busyness at IAH right now, you’ll want real- time TSA and airport queue updates, but I don’t have live feeds in this moment. The latest commonly used sources show IAH experiencing variable TSA wait times that can range from a few minutes up to around 30–40 minutes or more during peak periods, with occasional spikes during holiday travel or severe weather. For the most accurate read right now, check live TSA wait-time aggregators and airport status pages just before you head to the terminal. What to check for real-time accuracy

• TSA wait-time trackers: look for “live” or “current” wait times for IAH at TSA security checkpoints. Many sites display hour-by-hour averages and current conditions.
• IAH airport security updates: the airport or airline sites sometimes publish advisories about expected congestion, especially during peak travel times.
• Flight-queue/airport apps: services that pull real-time data from TSA and terminal queues can provide minute-to-minute estimates.

Tips to minimize time

• If you have TSA PreCheck or similar expedited screening, use it where available to cut typical wait times.
• Arrive earlier than you think you need; during busy periods, even a 30–60 minute buffer can save stress.
• Consider terminal and checkpoint variations; some days certain checkpoints move faster than others.
