Carry On Bags Are Stuffed In An Overhead Luggage Compartment On An Airplane

Make the most of that overhead bin space by finding the right carry-on suitcase, and learning the best way to pack it.

A carry-on bag is most people's security blanket, best friend and lifeline when traveling. Your carry-on often has essentials for the airplane - for me, that means mostly snacks but a carry-on may also include valuables such as passports, medicine, toiletries and cash. If you choose the right carry-on bag and pack it strategically, you can fit more and be hassled less as you move through the airport and TSA.

Following Transportation Security Administration guidelines for each major US airline is a must, and doing a little research on the latest rules and regulations can help you ace the experience without getting held up. (For more travel tips, explore the 12 travel essentials you need for every vacation and take a look at this travel checklist.)

What TSA officials do isn't in your control, but what you pack and how how you pack it for your next trip is. Here's how to pack your carry-on bag efficiently for your next business or pleasure travel.

The best carry-on travel bags

Before you start packing, you'll have to find the right carry-on bag. Here are a few important things to keep in mind.

What size carry-on should you get?

The first and most important aspect to think about is size. Federal Aviation Administration regulations say carry-on items can't exceed dimensions of 22 by 14 by 9 inches, though you might find an inch or two of difference depending on the airline. The general rule is that it must fit under your seat or in the overhead enclosed storage compartment on the plane. 

Here's a quick reference for size limits for the most popular US airlines.

Carry-ons should have an easy access tech compartment

If you decide to bring electronics like a laptop, iPad, Kindle or other tablet on board, your carry-on should ideally have a separate, padded compartment for secure packing. Be sure these compartments are easily accessible, since at security checkpoints, the TSA will require you to remove your electronic devices and place them in the plastic X-ray tray.

Make sure you're carry-on is comfortable on your back or shoulder

Remember, you'll need to lug your carry-on bag or suitcase across the airport and down long corridors, and you might even need to run with it so you don't miss your connection. Consider whether you need padded handles or cushioned straps or a backpack or a rolling suitcase for ease.

How to pack your carry-on the right way

Though what to pack in your carry-on ultimately depends on your preferences, there are a few guidelines for the best way to pack your luggage:

  • Pack items in layers (shoes one layer, clothes one layer, electronics one layer, etc.).
  • Pack the things you'll use the least at the bottom of the bag.
  • Keep most of your valuables in your carry-on luggage, and store them in side compartments or safely padded around other items.
  • Place valuables at the bottom of your bag, away from the opening.
  • Keep your wallet, credit cards and cash in an inner pocket so they'll be harder to steal.
  • Pack a small, separate bag for toiletries. (Liquids, gels and aerosols packed in carry-on must follow the 3-1-1 liquids rule: 3.4 ounces or less per container; all liquids must fit in one quart size, clear, plastic, zip-top bag; one bag per passenger.)
  • Roll your clothes tightly to save space in your luggage. 

Sometimes you lose your luggage. It happens. Though it's frustrating, it's important to pack a spare set of clothes (including socks and underwear!) in your carry-on to hold you over until your bags are found and returned. Pack clothing that can easily be rolled up and put in the bottom of your bag.

Essential items for your carry-on bag

There's some items that are just better in your carry-on luggage. If you do decide to check a bag, be sure to keep these items with you on the flight. Most of these carry-on essentials are items that would be hard to replace or purchase when you get to your destination. 

  • Prescriptions and medications
  • Contact lenses or glasses
  • Valuables like jewelry, wallets, passports, IDs and boarding passes
  • Cameras and smartphones
  • Entertainment like tablets, books and laptops
  • Headphones to watch TV or movies if a longer flight
  • Chargers for electronics
  • Printed itinerary, or hotel and flight confirmations

What you should never pack in your carry-on bag

The TSA has specific guidelines covering which items are banned from flights, and the agency takes those rules very seriously. In 2022 alone, the TSA screened nearly 761 million passengers and crew members nationwide, and it confiscated a record number of firearms (6,301) and many other items. TSA policy says that individuals carrying weapons, especially loaded firearms, can face fines or criminal penalties. 

These are some of the most commonly confiscated items:

  • Firearms
  • Fireworks
  • Box cutters, utility knives and razors
  • Bats, clubs and blades
  • Swiss Army knives
  • Sharp 

If in doubt, always refer to the TSA's guidelines on packing for flights, to ensure you have safe and easy travels.
