The best hand travel bags

Before you start packing, you’ll need to find the right carry-on bag. Here are some important things to keep in mind.

What size hand luggage should you take?

The first and most important aspect to consider is size. Federal Aviation Administration regulations state that carry-on bags cannot exceed dimensions of 22 x 14 x 9 inches, although you may find an inch or two of difference depending on the airline. The general rule is that it should fit under your seat or in the closed overhead storage compartment of the plane.

Here’s a quick reference to the size limits of the most popular US airlines.

Hand luggage must have an easy-access technical compartment

If you decide to bring electronics like a laptop, iPad, To light up or another tablet on board, your hand luggage should ideally have a separate, padded compartment for secure packing. Make sure these compartments are easily accessible, because at security checkpoints TSA will ask you to remove your electronic devices and place them in the plastic x-ray tray.

Make sure your carry-on bag fits comfortably on your back or shoulder.

Remember, you’ll have to lug your carry-on or suitcase through the airport and down long corridors, and you may even have to run with it so you don’t miss your connection. Consider whether you need padded handles or padded shoulder straps, or a backpack or rolling suitcase for ease.

How to pack your carry-on luggage correctly

While what to pack in your carry-on ultimately depends on your preferences, there are some guidelines for the best way to pack:

• Pack items in layers (shoes one layer, clothing one layer, electronics one layer, etc.).
• Pack the things you will use the least at the bottom of the bag.
• Keep most of your valuables in your carry-on and store them in the side compartments or securely around other items.
• Place valuable items at the bottom of your bag, away from the opening.
• Keep your wallet, credit cards and cash in an interior pocket so they’re harder to steal.
• Prepare a separate small bag for toiletries. (Liquids, gels and aerosols packed in carry-on baggage must follow the 3-1-1 rule for liquids: 3.4 ounces or less per container; all liquids must fit in a 1 liter clear plastic zipper bag; one bag per passenger.)
• Roll your clothes well to save space in your luggage.

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

Essential items for your carry-on

Some items are just better in your carry-on luggage. If you decide to check baggage, be sure to keep these items with you during the flight. Most of these carry-on essentials are items that would be difficult to replace or purchase once you arrive at 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 for watching TV or movies on a longer flight
• Chargers for electronic devices
• Printed itinerary or hotel and flight confirmations
