Carry-On Only: Packing List for a Family of Four

Carry-On Only: Packing List for a Family of Four

ByEvan Parker

Traveling light with a family sounds like an impossible dream—especially if you’ve ever found yourself at the airport, sweating over an overweight checked bag and digging through a suitcase for a lost toothbrush. My family has been there more times than I’d like to admit. But two years ago, after a wildly expensive baggage fee incident in Atlanta, we committed to a new rule: carry-on only, even for a family of four, even for trips up to 10 days.

So, how do you actually pull this off without sacrificing comfort (or sanity)? Here’s our real-world method for streamlined, carry-on only family adventures—complete with what to bring, what to ditch, and a step-by-step plan that genuinely works, even with kids.

Why Carry-On Only?

“We missed a connecting flight once because our bags got lost. Now, I’d rather wash socks in a hotel sink than play luggage roulette ever again.”

Going carry-on only isn’t just about saving a few bucks (though, hey, $35 per checked bag adds up fast). You also skip the baggage claim lines, roll off the plane and into your adventure, and never worry about lost luggage. Plus, you’re forced to pack smarter—less stuff, less stress.

Our Typical Trip Scenario

Here’s the context: family of four (two adults, two kids ages 6 and 9), 5 to 10 days, flying economy, staying in a mix of hotels and rentals. Most of our trips involve city exploring, some hiking, and maybe a beach stop. Weather? Sometimes predictable, sometimes not.

Step-by-Step: The Realistic Family Packing Game Plan

Step 1: Pick Your Luggage

  • Adult Carry-Ons: 2x 22″ hard-shell spinners (meets most airline requirements)
  • Kids’ Bags: 2x small rolling suitcases or sturdy backpacks (fits under seat)
  • Personal Items: 2x medium backpacks (adults), 2x small daypacks (kids)

Pro tip: If you’re flying budget airlines in Europe or Asia, always check their size rules—they can be stingy.

Step 2: Clothing—The Power of the 5-4-3-2-1 Rule

Here’s our golden packing ratio for each traveler (adult or kid):

  • 5 sets of underwear and socks
  • 4 tops (t-shirts, shirts, etc.)
  • 3 bottoms (pants, shorts, skirts, leggings—your combo)
  • 2 pairs of shoes (one worn, one packed)
  • 1 lightweight jacket or sweater

Adjust for weather. If laundry is possible, you can stretch this list for trips up to two weeks.

Step 3: Must-Have Extras

  • 1 swimsuit per person (if you’ll swim)
  • 1 hat and sunglasses per person
  • Small packable rain jacket (if rain is likely)
  • Travel-size toiletries (shared wherever possible)
  • Electronics: phones, chargers, universal adapter, e-readers/tablets (loaded with books, movies, offline maps)
  • Travel laundry soap sheets or a small bottle of Dr. Bronner’s
  • Minimal first-aid kit (band-aids, ibuprofen, kids’ meds if needed)
  • Reusable water bottles (empty through security!)
  • Snacks: a few granola bars, nuts, or whatever your kids will actually eat

Step 4: The “Don’t Even Pack It” List

  • Bulky towels (rent them at the beach or pool)
  • Multiple pairs of shoes (seriously—two is enough)
  • Heavy books (use a Kindle or download to your phone)
  • Full-size toiletries (buy at destination if needed)
  • Hairdryers (most hotels have them)
  • “Just in case” outfits (you won’t wear them)

Step 5: Packing Technique (aka Tetris Mastery)

  • Roll clothes instead of folding—less wrinkling, more space.
  • Use packing cubes (one per person, color-coded). Total game changer for family sanity.
  • Shoes go at the bottom, stuffed with socks and underwear.
  • Fill gaps with small items: chargers, toiletries, swimwear.
  • Keep a change of clothes and basic toiletries in your personal item—just in case your main bag has to be gate-checked (trust me).

A Quick Real-Life Story (Optional Reading, Humor Included)

Last summer, my daughter insisted on bringing her “lucky” stuffed llama, which took up half her carry-on. I caved, of course. Halfway through the trip, she decided the llama was “too big” and asked if we could ship it home. Now, my rule is simple: if it doesn’t fit with all your other stuff, it stays. (The llama still lives with us, but only travels virtually now.)

Final Thoughts

Packing carry-on only as a family isn’t just possible—it’s freeing. You’ll move faster, argue less, and probably spend less money. And even if you end up washing socks in a hotel sink at midnight, you’ll have more adventures and less baggage (literally and figuratively).
