The short answer: Pack a carry-on for a week by choosing a 40L bag, rolling clothes into packing cubes, wearing your bulkiest items, and using travel-size toiletries. Stick to a capsule wardrobe with mix-and-match pieces, and you’ll fit everything into the overhead bin.
Many travelers think they need a checked bag for a week-long trip, but that’s simply not true. With the right strategies, you can easily fit everything you need into a carry-on. Not only does this save you time at the airport (no waiting at baggage claim), but it also saves money, as many airlines now charge for checked bags. Plus, you eliminate the risk of lost luggage. The key is to plan ahead, choose versatile clothing, and use smart packing techniques.
Your carry-on should be around 40 liters or less, with dimensions that fit your airline’s requirements (typically 22 x 14 x 9 inches). A backpack or a small rolling suitcase works well. If you’re considering a backpack, look for one with anti-theft features like lockable zippers and RFID-blocking pockets to keep your valuables safe.

Limit yourself to 5 to 7 outfits that can be mixed and matched. Choose a color palette of 2 to 3 neutral colors (like black, gray, and navy) with a few accent colors. For a week, you’ll need:
Remember, you can wash clothes in the hotel sink or use a laundry service if needed. Plan to wear each item at least twice, and you’ll have plenty of options.
Rolling clothes is more space-efficient than folding, and it helps reduce wrinkles. A good technique is the ‘bundle wrap’ where you roll small items into larger ones. For example, roll a pair of socks and tuck them into a pair of shoes, then stuff the shoes into a shower cap to keep dirt off your clothes.
Packing cubes are a game-changer. They compress your clothes and keep everything organized. Use one cube for tops, one for bottoms, and a smaller one for underwear and socks. You can even use a cube as a dirty laundry bag. When you arrive, you can unpack the cubes directly into drawers.
To save space, wear your heaviest shoes, your jacket, and any bulky sweaters. This includes your jeans if they’re thick. You can also layer: wear a t-shirt, a button-down, and a sweater. This not only frees up space but also keeps you warm on the plane. If you have a scarf, wear it or tie it to your bag. Avoid wearing high heels; pack a pair of foldable flats for dressier occasions.
Follow the TSA 3-1-1 rule: 3.4-ounce (100ml) bottles in a single quart-sized clear zip-top bag. Instead of full-size bottles, invest in travel-size containers and fill them with your favorite products. Many hotels provide shampoo, conditioner, and soap, so you might not need to bring those at all. If you’re staying in a rental, consider buying toiletries at your destination.
For electronics, bring only the essentials: your phone, charger, earbuds, and maybe a power bank. A tablet or laptop is optional; if you need one, it can go in a personal item (like a backpack) that fits under the seat. Keep cables organized in a small pouch to prevent tangling.
Can I bring a carry-on and a personal item? Yes, most airlines allow a carry-on (overhead bin) and a personal item (under the seat), such as a purse, laptop bag, or small backpack. Use this to your advantage: put your electronics, documents, and a change of clothes in your personal item in case you need something during the flight or if the overhead bins are full.
How do I handle liquids like shampoo and conditioner? Transfer them into 3.4-ounce travel bottles. You can buy reusable silicone bottles or use the ones that come with sample sizes. Remember to place them in a clear zip-top bag and have it easily accessible for security screening.
What if I need to pack a suit or formal wear? Use a garment folder to keep suits and dresses wrinkle-free. Fold the pants and jacket carefully, or roll them inside a packing cube. If you’re really worried, you can ask the flight attendant to hang your garment in the closet, but that’s not guaranteed. Alternatively, choose wrinkle-resistant fabrics like wool blends or synthetics.
