Okay, not because I think you need to worry about cavity searches but just because it will make the whole experience smoother and less stressful - my airport tips.
Follow their rules, read the website the night before your flight just in case anything changes but as of today:
Have your boarding pass and ID in your hand when you reach security. If your carry on has a zip up side pocket that’s the perfect spot for them until that point.
Put all your liquids in one ziploc bag and make sure the total is not greater than 3 oz. Pro tip - toothpaste and other gel like substances are liquids. If you need to take more than that you’ll need to check a bag. Remember to take the ziplock bag out and put it in the bin separately.
Don’t wear a lot of metal jewelery, large belt buckles etc. I used to fly with no underwire bra and zipperless clothes but the metal detectors seem to be set better now and those don’t matter anymore but an arm of bangles is a poor choice.
Wear shoes that you can get in and out of easily. With you being 60+ and the recent changes you might not have to take your shoes off but better to be prepared.
When walking through security keep an eye on your possessions at least until they’re into the xray machine. Once you’re through grab your stuff and move to one of the reassembly areas to put everything back into your bag. At this point check that you have everything.
If you’re carrying on two items (carryon bag and personal item) have everything you need to access during the flight in the smaller bag. Getting into the overhead bins during the flight is a pain and you don’t want to deal with that if you don’t have to.
Give yourself time to get through security without rushing.
Bring a sweater or a scarf for the plane. They go nuts with the AC.
Bring an empty water bottle and fill it up after security. Drink lots while you’re in flight the extra bathroom trips are worth not getting dehydrated.
Even if you have an ereader you may want to bring a small magazine or book for the “turn all electronics off” times. I get bored easily so this one is important for me
