3 Weeks in Europe, One Carry-On — The Honest Trip Report

런던 — 3주 유럽 여행의 첫 번째 도시 (2026년 2월)

I want to start by being honest about where I was two months before this trip: sitting in my living room, staring at a half-packed suitcase, seriously considering just checking a bag for a third straight European vacation.

Then I did the math. London to Paris by Eurostar, then Amsterdam by train, then Rome by plane. Four cities. Four different check-in scenarios. Baggage fees that would have run me $180+ roundtrip — and that's before the time spent at carousels, the stress of delayed luggage, and the reality of rolling a large suitcase across cobblestones in Rome at midnight.

I used the TripPacked Carry-On Checker to verify my bag dimensions across all the airlines I'd be using (British Airways and Ryanair both on this trip — very different size limits), rebuilt my entire packing approach around what it allowed, and committed to carry-on only.

Three weeks, four cities, zero checked bags. Here's what actually happened.

The Route

The Bag I Used

An Osprey Farpoint 40 for the main carry-on, plus a small packable daypack (Matador Freerain24) that stuffs into a tennis-ball-sized pouch when not in use. The Matador counts as a personal item and is invisible when packed inside the Osprey during flights.

This combo is the single most flexible travel setup I've found. The Farpoint meets most European airline carry-on limits. The Matador means I have a full-size day bag at every destination without any added bulk on travel days.

What I Packed — 21 Days in Europe

The Laundry Strategy

This is what makes 3 weeks in one carry-on actually possible. I did laundry twice — once in Paris (used the hotel's guest laundry, €8 for a full cycle), once in Rome at a self-service laundromat two blocks from my Airbnb (€6 total).

Merino wool pieces could be hand-washed in the sink and dried overnight. I washed the t-shirts every 3–4 days this way. The pants and button-down went through the actual machines. Total laundry time across 3 weeks: about 2 hours, cost: €14.

Checked bag surcharges: $0. Time at baggage carousels: 0 minutes. Cobblestone rolling damage: none.

The Hardest Moment

Amsterdam, Day 2. It was cold and raining sideways. I'd done 14,000 steps on wet cobblestones. I walked past a beautiful wool overcoat in a shop window on the Jordaan canals, and I wanted it. It was the perfect Amsterdam coat. It was also absolutely not fitting in my bag.

I stood outside that shop for five minutes in the rain making the classic overpacked traveler's calculation: is this worth the problem it creates?

I walked away. I've thought about that coat twice since. But I also remember arriving at Rome Fiumicino at 11:30pm, walking straight past baggage claim, and being in my Airbnb bed by 12:15am. That memory is more satisfying than any coat.

City-by-City Packing Notes

London

Rain jacket is absolutely mandatory, not optional. The rest of the UK packing advice you've read is accurate: layer up, expect grey. The good news: London has outstanding thrift stores if you need anything. Seven Sisters Market and Portobello Road are cheap and excellent.

Paris

Paris dresses up more than London. The button-down shirt earned its weight here. I also bought a silk scarf at a market — flat, extremely packable, extremely French, and actually useful as a light layer. Best souvenir I've ever bought.

Amsterdam

Windier and wetter than expected in March. The packable rain jacket got real use here. Amsterdam's streets are beautiful and cobblestoned in ways that make rolling luggage genuinely difficult — the backpack setup was even more valuable here than expected.

Rome

The warm surprise of the trip. 18°C and sunny — I peeled off layers and spent most of the time in a single merino t-shirt. Also: cobblestones that make Amsterdam look smooth. The backpack was the right call.

Would I Do It Again?

I'm planning Portugal and Spain for later this year — 10 cities in 3 weeks. Same bag. Already started building the packing list on TripPacked.

The thing nobody tells you about carry-on travel is that it changes your entire relationship with a trip. You stop thinking about your luggage. You stop worrying about what gate it went to, whether it got transferred correctly, whether it'll be waiting when you land. It just becomes a non-issue, and all that mental bandwidth goes to the trip instead.

That's worth more than a coat.
