...stays at the airport?? lol
Adding to what the others said, it is very helpful to feel like YOU are organized. Here are some of the things I do particularly for Airport Security:
-Wear clothes that don't have any metal decorations. I usually try to wear pants that are pull on and don't have a zipper, but if you wear jeans you will probably be OK. Just don't wear ones that have a bunch of extra studs on them. (Are they popular anyway?? I live in Idaho so have no idea! lol) Do you usually wear an underwire bra? If you can avoid wearing one, do as they will sometimes set off the security scanner.
-Take ~everything~ out of your pockets. I usually have a chapstick in my pocket and altho my teeny airport has the regular scanners not the nude-o-scopes (total body scanners) I make myself go thru the routine before I get to security so I am prepared when I am leaving from a big airport to come back home. As I understand it, the total body scanners will even pick up a Kleenex in your pocket so have everything out.
-I take off my watch, FitBit, earrings, any jewelry, money belt. Actually when I dress at home I put all the stuff I normally wear into a ziplock bag (marked laughingly JOTD - Jewelry of the Day!) and put it in my purse right then so I don't forget it. This step is on my Leaving Home checklist. Yes, I have one.
-Do you have any artificial joints - knees, hips, shoulders? It works best if you tell the security person BEFORE you go thru as you will set it off and they will want to wand you on the other side. I don't have artificial joints but SIL has both hips and she is usually treated very nicely when she tells them ahead.
-Many wear shoes they can slip off, but I just wear my athletic shoes. When you approach the security area and are in line, start untying your shoes. I grab 2 bins to put things in. First bin is my shoes, sweater and 3-1-1 bag. Second bin is my purse or tote or backpack, completely zipped up. Behind those I put my carry on on the belt. I hold my hand against the first bin and I wont let it go thru the scanner until they are ready for me to walk thru. Truthfully at my little airport this is not a problem but I want to be thru the scanner when my purse comes thru.
***IF on your boarding pass you have the words TSA Pre-Screened you can leave your shoes on. Since you haven't flown a lot you probably will not have this unless you have purchased the Global Entry permit from the government. Don't worry about this if you don't have it.
-In the US I've not had to pull out my phone, Kindle or iPad Mini altho they will often ask. I leave them in ZIPPED compartments if they don't want them out.
-Don't get in a hurry. Take your time even if you feel people are trying to push you thru. It does drive me nuts when someone who looks like they fly a lot will wait until they are at the scanners to start taking things out of their pockets, taking off their belts, taking off their jackets, but maybe they don't fly a lot. If I get flustered, I feel like I will forget something. In fact one time I walked away from security without my 3-1-1 bag. They had sent it back thru to be rescreened and I didn't notice. Fortunately it was in my small airport and just steps away. Now I have my name and address taped to the outside.
-Go thru your purse the day before you leave when you are packing. Take out excess change that might have gathered at the bottom, organize stuff so you will know where it is, look for things you might normally have in your purse that need to go in your 3-1-1 like eye drops, hand lotion or Purell.
This will be easier than you think it will be. Is your airport near your house? If you are anxious and it's convenient, you might make a dry run and go stand and watch how people go thru the security lines.
You are going to have a wonderful time!
