Make removing your shoes easy. The TSA requires passengers to remove their shoes when passing through the metal detector. There is not much room to squat down. People will try to pass around you and benches are inconveniently far from your bags. Wear shoes that you can slip off without bending down or undo your laces before getting in line and tuck them into your shoe. This way you will be able to slip them off easily to be place on the X-ray belt.
