Which Security Line Is Faster – Left or Right?

Here’s a little-known trick: the left security line is often faster.

Why? Most people are right-handed and instinctively veer right. TSA agents have confirmed this pattern at multiple airports.

Other Quick Line Tips

Avoid the center lanes. They’re visible first and attract the most traffic. Edge lanes—especially far left—move quicker.

Watch the families. Lines with lots of strollers and car seats take longer. A line of business travelers in suits? That’s your express lane.

Check the belt watchers. If a TSA agent is actively managing a lane and looks experienced, that line usually flows smoothly.

The Real Speed Hack

Regardless of lane choice, the biggest time-saver is being prepared: laptop out, liquids accessible, shoes ready to remove. The person who fumbles at the belt costs everyone 30+ seconds.

Be the prepared traveler, pick the left lane, and watch others wonder how you breezed through.
