Welcome to FT.

If you have PreCheck, make sure you are not wearing anything metal that might set off the metal detector. I go through wearing only medically required items - eye glasses and wedding ring.

If you do not have PreCheck you will need to go through either a pat down by another female or go through the body scanner. The latter of which are notorious for giving false positives which will result in a cursory pat down. As such, make sure everything is out of your pockets and you are not wearing bulky clothing.

Anything you take off put into your carry on bag - not into the bowls that others maybe tempted by if for some reason you are held up or distracted.

All of the above really applies to all fliers which helps them avoid a secondary inspection.
