How to Pack for 3 Weeks in a Carry-On: An Easy Guide
Packing for a three-week trip with just a carry-on might seem daunting, but it can be the best way if you have the right strategy. Whether you're jetting off to explore European cities, basking on tropical beaches, or adventuring through mountain trails, here’s how to pack smart and travel light.
My thought process behind packing light always starts with flexibility. I want to be able to pack and carry everything I have with ease to eliminate stress. With a carry-on, I can seamlessly transition from one plane to another without waiting at baggage claim, even if I have a layover or delay, before taking a train or taxi to my final destination.
Another thing that always keeps me from packing a checked bag is the thought 'What if it doesn't make it?'. I like to eliminate that option from my travels especially if I am traveling farther with multiple legs, which have a higher chance of delays or missed flights.
Here are the steps on how to pack a carry-on for every trip, regardless of the length of time traveling.

1. Choose the Right Carry-On
Start with the right carry-on suitcase. Opt for one that maximizes space while adhering to airline size restrictions. Look for features like:
Expandable sections: To provide extra space when needed.
Compression straps: To help reduce bulk.
Multiple compartments: For organized packing.
2. Plan Your Outfits
The key to a streamlined wardrobe is versatility. This helps so much when packing a carry-on. Choose pieces that can be mixed and matched easily. Here is an example:
3-4 Tops: Opt for neutral colors and breathable fabrics.
2-3 Bottoms: A mix of jeans, trousers, and shorts.
2 Dresses/Skirts: For versatile day-to-night outfits—you can never go wrong with a little black dress here.
1 Light Jacket, Sweater, or long-sleeved shirt: For cooler evenings.
1 Heavy Jacket (if necessary): Wear it during travel to save space.
7-10 Pairs of Underwear and Socks: Enough to last between washes.
1-2 Pairs of Shoes: A comfortable pair for walking and a dressier option.
Lay it all out and get a good idea of how many outfits you have and visualize each day of your trip making sure you have something that works for any activities planned.
3. Utilize Packing Cubes
Packing cubes are game-changers for organization and space-saving. Use them to categorize your clothes, separating tops, bottoms, and undergarments. For clothes like tops and bottoms, I use a large packing cube, and for small things, like undergarments, socks, and workout clothes, I use smaller cubes.
Roll your clothes to maximize space and minimize wrinkles.
I also use a packing cube for my shoes to keep them separated from clean clothes and a spare empty cube for dirt clothes as well.

4. Limit Toiletries
Carry only essential toiletries. Most hotels and accommodations provide basics like shampoo and soap. Use travel-sized containers for items like:
Toothpaste
Moisturizer
Sunscreen
Makeup (just the essentials)
Remember, liquid items must be 3.4 ounces or less per container for air travel

I keep my travel toiletry bag prepped with basic necessities and travel-size containers, eliminating the need to pack from scratch each time.
For longer trips, I pack my toiletries bag in my personal bag that I place under the seat in front of me on the plane for easy access. This way, I can take it to the bathroom to brush my teeth or wash my face.
Here is the exact one I use:
5. Consider a Capsule Wardrobe
A capsule wardrobe is a minimalist approach where each item complements the others. Choose a color palette that allows you to mix and match effortlessly, creating multiple outfits from a few pieces.
6. Smart Accessories
Accessories can change the look of an outfit without taking up much space. Pack items like:
Scarves
Jewelry
Hats
Belts
7. Carry-on Tech
E-reader or Tablet: Instead of bulky books. (I use the library app or iBooks on my phone to eliminate just one more thing)
Phone and Chargers: Don’t forget adapters if traveling internationally.
Earbuds or Headphones
Just like my toiletries, I keep a prepped travel charger case, which is great for long trips or even weekend getaways.
8. Laundry Solutions
Planning to do laundry while on your trip can significantly reduce the amount you need to pack. Most hotels have a laundry service and provide laundry bags in the closets of the hotel rooms.
When booking Airbnbs, I always check for a washer and dryer. If that’s not an option, a laundromat is a great way to freshen up clothes mid-trip.
Bring:
Travel-sized laundry detergent or detergent sheets
A small packable bag or even a plastic bag for dirty laundry. Store your dirty clothes with a dryer sheet to keep them as fresh as possible.
Use hotel room hangers or a foldable drying line to hang wet items overnight.
9. Pack Multi-Use Items
Opt for items that serve more than one purpose. A sarong can double as a beach towel or a shawl. A light rain jacket can also be a windbreaker.
10. Be Strategic with Packing
Layer heavy items on the bottom: Shoes and bulkier items should go at the bottom.
Fill shoes with smaller items: Socks, belts, and chargers can be stored inside shoes to save space.
Use every inch: Fill in gaps with rolled-up clothes or small items.
11. Stay Organized
Keep important documents, medications, first aid kit, and valuables in a personal item like a backpack or a purse that you can easily access. Use a small pouch or ziplock bag to keep your travel documents, passport, and boarding passes handy.
12. Final Check - for your carry-on
Before you zip up your carry-on, do a final check to ensure you have everything you need and nothing you don’t. Remember, you can always buy items at your destination if you forget something. I always remind myself the only thing you can't buy is a passport so as long as you have that you are good.
13. Example of a Packing List
The first thing to do is make a list of everything you want to take, that way you can make it over the weeks leading up to your trip when something pops into your head and you won't forget. Then pack everything on the list; if you have plenty of space, congrats, you did it. If you have less space than you need, start the process of elimination.
Here is an example of my full packing list:
Carry-On Suitcase
- Shoes: Running shoes and sandals (or heels if there is an event)
- Running Clothes: Sports bra, top, bottom, socks (X the number of days planning to work out)
- PJs
- 2 Dresses
- Skirt / Shorts
- 2 Pants
- 4 Tops
Backpack
- MacBook Pro
- AirPods
- Water Bottle - Hydro Flask
Wear on the Plane
Sneakers
Jeans
T-shirt
Sweater
Weather Considerations
When packing for a longer trip, it’s important to keep climate change in mind. A general rule of thumb is to pack layers that can be easily added or removed as needed. For cooler weather, think about including a light jacket or trench coat, and make sure to have a few long-sleeved shirts for added warmth. For warmer destinations, a pair of shorts and a breathable shirt will be your go-to. If your trip involves fluctuating temperatures, items like a solid shampoo bar can save space in your toiletries, while a travel-sized sunscreen is a must. Packing versatile items ensures you’re prepared for changing weather without taking up too much space.
Packing for Activities
Your activities can greatly influence what you need to bring. For outdoor adventures like hiking or exploring, consider packing a smaller day pack that you can carry for those active travel days. A water bottle, extra shoes, and even a lightweight rain jacket can make all the difference. For city trips or evenings out, opt for a dressier option like a versatile dress or a pair of pants that can be dressed up or down. If you’re planning on lounging by the pool or beach, don’t forget a compact beach towel and flip-flops, and they won’t take up much room in your carry-on. The key is to balance the number of things you pack with the types of activities you plan to enjoy.
