How to Pack for a Flight and a Week
Share

You know the moment. It's the evening before your flight. An open suitcase lies on the floor, surrounded by a mountain of clothes, gadgets, and shoes. You try to rationally plan what to bring, but your mind is racing with "what ifs": "What if it gets cold? What if we go to a fancy restaurant? Maybe I should take those third pair of shoes, just in case."

 

But this isn't just any trip. After landing in sunny Alicante or dynamic Warsaw, a car from a car rental company is waiting for you. This means a week of complete freedom, spontaneous plan changes, and discovering places you couldn't reach any other way. And here lies the challenge: how do you reconcile airline baggage limits with the needs of a comfortable, week-long road trip? How do you pack light for the flight but smart for the car journey?

 

The answer is minimalist travel. It's not the art of giving things up, but the art of intelligent choice. Here is a proven guide on how to fit everything you need into a single carry-on suitcase and enjoy complete freedom – from the moment you leave home until you return the car keys.

In this article:

Step 1: The Foundation – The Perfect Suitcase and Strategy

Before you start packing, choose the right tools. They will define your limits and enforce discipline. 

 

  • A carry-on suitcase on wheels: This is your best ally. Why? First, you save on checked baggage fees. Second, you don't waste time at the baggage carousel after landing. Third – and this is key – you are 100% sure it will fit in the trunk of any car from a car hire company's fleet, even the most compact one. 
  • Packing cubes: These are an absolute game-changer in organization. They allow you to compress clothes, divide them into categories, and maintain perfect order throughout your trip. No more digging through your entire suitcase to find a clean pair of socks. 
  • A backpack as your personal item: In addition to the suitcase, take a comfortable backpack. This is where you'll keep your most valuable items: electronics, documents, and a small toiletry bag, in line with airline requirements.

Step 2: The Capsule Wardrobe – The Secret of a Stylish Minimalist

This is the heart of the whole process. A capsule wardrobe is a small collection of clothes where almost every item matches every other, allowing you to create many different outfits.

 

How to build one for a week-long trip?

 

  • Choose a color base: Stick to 2-3 neutral colors that work well together (e.g., white, black, beige, navy, grey). 
  • Add one accent color: Add one bolder color to your neutral base (e.g., olive, mustard, terracotta) to liven up your outfits. 
  • The 5-4-3-2-1 Rule (example for a summer trip): 
    • 5 tops (e.g., 3 T-shirts, 1 linen shirt, 1 tank top) 
    • 4 bottoms (e.g., 1 pair of jeans, 1 pair of shorts, 1 pair of chinos, 1 skirt/dress) 
    • 3 pairs of shoes & accessories (e.g., 1 pair of comfy sneakers, 1 pair of sandals, 1 pair of dressier shoes, 1 belt, 1 scarf) 
    • 2 outerwear items (e.g., 1 light jacket/denim jacket, 1 sweater/hoodie) 
    • 1 swimsuit, 1 watch 
  • Materials matter: Choose clothes made from wrinkle-resistant fabrics (e.g., merino, lyocell/Tencel) or those that look good slightly wrinkled (linen!). 
  • Roll, don't fold! This is the most effective way to save space and avoid wrinkles. Place tightly rolled clothes into packing cubes.

Step 3: Toiletries and First-Aid Kit Under (Changing) Rules

The liquid limit in carry-on luggage (100 ml per container) is a rule that, thanks to modern CT scanners at airports, is slowly becoming a thing of the past. However, before you gleefully pack a full bottle of your favorite shampoo, be sure to check the regulations at your specific departure and arrival airports.

For now, the safest and most universal strategy, which also supports minimalism, is to stick to smaller containers.

 

  • Travel-size versions and samples: Pour your favorite cosmetics into small, reusable bottles. Collect samples of creams and perfumes – they are perfect for travel. 
  • Solid toiletries: Shampoo, conditioner, or shower gel in bar form are a minimalist's dream. They are not subject to liquid limits, take up extremely little space, and will never leak. 
  • First-aid kit: A small, handy kit is enough: painkillers, plasters, something for stomach issues, and any personal medication you take regularly.

Step 4: Electronics – The Smart Minimum

  • One universal adapter with USB ports: Instead of several chargers, take one that can charge your phone, power bank, and watch simultaneously. 
  • Power bank: An absolute must-have on a road trip when navigation drains your phone's battery. 
  • E-reader: Instead of heavy books, take an entire library in one lightweight device. 
  • Phone mount for the car: A small but crucial gadget. It's worth asking when renting a car if the vehicle is equipped with one, or if it's better to bring your own just in case.
