      There's a distinct feeling of dread that creeps in while you watch the luggage carousel keep spinning after everyone else has collected their bags. You begin to bargain with the universe, promising yourself that if your suitcase arrives in the next five minutes, you’ll never overpack again. I’ve been there far too often. In the midst of delayed flights, gate changes, and the anxiety of lost luggage, I made a firm decision to stop using checked bags for good.

      However, that turned out to be easier said than done. Minimalism isn’t my style. I appreciate having options. I want an outfit suitable for a wine tasting and another one for a city sightseeing tour. Recently, during a jam-packed trip to Napa Valley, I needed all of that—along with my skincare essentials and a selection of shoes that could transition from off-roading adventures to farm-to-table dining. With just three days for the trip, the last thing I wanted was to waste time waiting for my luggage on the dreaded carousel.

      After years of traveling with just a carry-on (from weekend trips to extensive international journeys), I’ve crafted a packing strategy that has never let me down. It’s efficient and thoughtful while allowing for a fun top. On that Napa excursion, I managed to fit everything I needed into my Away carry-on with no stress, no compromises on style, and—importantly—no checked luggage. When opting for solely a cabin bag, making careful choices about what to bring is essential to ensure you have everything required without the risk of overpacking.

      Are you planning a trip soon? Here’s how I pack a carry-on to optimize space without sacrificing style.

      My 2-5-1 Carry-On Packing Formula

      I refer to it as the 2-5-1 method: two bottoms, five tops, and one outer layer. That’s all. It may seem simple, but the key lies in choosing versatile pieces. I typically select one casual bottom (like baggy jeans or linen pants) and another that can be dressed up or is suitable for a specific activity (such as tailored trousers, a flowy skirt, or— for my Napa trip—utility shorts that paired well with a tank and were suitable for outdoor activities).

      Having five tops gives you enough variety without going overboard. I categorize them as follows: one for daytime wear (like a ribbed tank), one for evenings (a more refined option), one that’s functional for active situations (something that can transition between workouts and regular wear), and two interchangeable options to pair with different plans. If each top works with both bottoms, you’ve effortlessly created at least ten outfit combinations.

      The outer layer is the last element (and it’s vital to consider your itinerary). I usually include one jacket that can adjust to either a casual or formal setting, depending on the trip's atmosphere. I often choose items like a light denim jacket, a cropped blazer, or a linen shirt that can be layered or worn alone. You only need one jacket, so it should be adaptable. Extra points for pockets.

      Before You Start

      Confirm your airline's carry-on size restrictions: Always check the particular guidelines of your airline, whether you're taking a domestic or international flight. Major U.S. airlines such as American Airlines, Delta, and Southwest often permit slightly larger carry-ons compared to international carriers.

      Be aware of TSA regulations for toiletries: The TSA permits liquids in containers of 3.4 ounces (100 milliliters) or smaller, and all liquids, creams, and gels must be contained in a single quart-sized bag. Depending on the airport, you may need to take your liquids bag out of your carry-on for security checks. With this in mind, keeping it in an easily accessible part of your bag is beneficial.

      Check the weather forecast for your destination: Look up the 10-day forecast for your location and note any significant temperature variations, chances of rain, and wind or humidity levels. This information will help you select outfits that suit your trip and avoid unnecessary items, ultimately conserving space in your packing.

      Draft a list of essentials: Before you begin packing, create a brief list of must-haves to prioritize space and ensure no important item is forgotten. This could be something as straightforward as the outfit for a wedding you're attending or a swimsuit for a beach trip. Identifying your essentials first helps you structure the rest of your packing list around them.

      Take care of your laundry: Nothing speeds up the packing process like having your entire wardrobe at your disposal. Doing laundry ahead of time allows you to "shop your closet" rather than scrambling to find clean basics or discovering that your favorite travel outfit is still in the wash.
