How to Go Through Airport Security Like a Pro (First-Time Traveler’s Guide)

If you’ve never flown before, airport security can feel intimidating. Everyone seems to know exactly what to do, while you’re standing there wondering if your shampoo is too big or if you’re about to hold up the line.

Don’t worry — once you know the steps, it’s simple. After 15 years of airports around the world, here’s my step-by-step guide to getting through security smoothly, without the stress.

1. Prep Before You Even Leave Home

• Liquids & gels: Must be in containers 100ml (3.4oz) or smaller, inside a clear, resealable bag.

• No aerosols: Leave them at home or pack them in checked luggage — they’re not allowed in carry-ons.

• Electronics: Laptops, tablets, and cameras need to come out of your bag and their protective sleeves.

• Travel documents: Keep your passport/ID and boarding pass in an easy-to-reach pocket.

💡 JD’s Tip: Put your liquids bag and laptop right at the top of your backpack. You’ll thank yourself in the line.

2. Know the Dress Rules

• Shoes: Usually stay on in most countries, but in the USA, you’ll be asked to remove them (so wear socks!).

• Outer layers: Jackets, coats, and bulky hoodies need to come off.

• Metal items: Belts, watches, coins, and heavy jewelry can set off alarms — tuck them into your bag early.

Wear easy layers — jackets always come off at security.

3. At the Security Line

• Have your ID and boarding pass ready to show.

• Start unzipping and organizing while you wait.

• Use the bins in this order:

1. Liquids bag and electronics (separate bin)

2. Jacket, belt, and metal items

3. Carry-on suitcase/backpack

💡 JD’s Tip: Even if you bought water inside the airport, you can’t take it through security unless you’ve already cleared the checkpoint.

4. If Your Bag Gets Flagged

Sometimes your bag is pulled aside for extra screening. It happens to everyone — often because of liquids, batteries, or food. Stay calm, answer the officer’s questions, and you’ll be on your way in minutes.

5. Repack and Move On

• Step aside to re-pack your things so others can collect theirs.

• Double-check for your passport, phone, and wallet before walking away.

🚫 What NOT to Pack in Your Carry-On

A few items almost always get confiscated:

• Aerosols (hairspray, deodorant, bug spray)

• Bottles larger than 100ml / 3.4oz (even if you bought them at the airport)

• Sharp objects (scissors, pocketknives, nail files)

• Lighters or matches (rules vary, but it’s best to skip them)

• Large sports gear (bats, trekking poles, fishing rods)

• Tools or any item that could be considered a weapon

💡 JD’s Tip: If you’re unsure, check your airline’s website or the airport’s “Security & Prohibited Items” list before you pack.

Final Thoughts

Airport security might feel overwhelming the first time, but once you understand the flow, it’s easy. With a little prep and a calm mindset, you’ll glide through like a seasoned traveler — and have extra time for coffee or duty-free shopping before your flight.

💡 JD’s Tip: The more organized you are, the faster you’ll move through. Think “easy access, minimal metal, clear liquids,” and you’re golden.
