Packing · Travel Light. Travel Smart.

One carry-on.
That’s it.

The teachers who've led fifteen trips pack lighter than the students on their first. Borrow their list.

Why this matters

The carry-on rule isn’t a suggestion. It’s the difference between a great trip and a hard one.

Picture Florence, near the Duomo: most of the most charming hotels are in 300-year-old buildings with small elevators. Picture Lisbon: cobblestone hills steep enough to be staircases. Picture the train station in Munich during a transfer. Now picture all of that with a large suitcase.

A 21-inch carry-on changes the trip. You’re mobile. Every Tour Director on the Passports payroll travels carry-on only — they know.

Pack this

Six categories. The full kit.

Use this as your packing checklist the night before. If something doesn’t appear in one of the six categories below, ask yourself why it’s in your bag.

Climate adjustments

Layers beat thick coats.
Always.

Whatever season your tour falls in, the answer is layers. A cathedral is colder than the cafe across the street. A bus ride is colder than a coastal walk. Subtract layers as you go and you’ll be comfortable for nine days straight.

Summer

Light, modest, sun-prepared.

  • Lightweight long-sleeved layer for cathedrals + AC
  • Modest cover-up — sleeveless tops won’t enter many sites
  • Wide-brimmed hat + UV sunglasses
  • SPF 50, reapply every 2 hours
Spring / Fall

The layering classic.

  • Tee → long-sleeve → fleece → light rain shell
  • Compact umbrella or poncho — Europe rains horizontally
  • Closed-toe shoes; the cobblestones get slippery
  • One warm hat for evenings
Winter

Warmth without bulk.

  • Packable down + thermal base layer
  • Wool socks; cotton stays wet, wool stays warm
  • Waterproof boots, broken in
  • Gloves, hat, scarf — wear them, don’t pack them
Pack this, not that

A short list of things to leave home.

Every item in this column has been the source of a regret on a previous tour. We have the post-trip surveys. Here’s the list.

01

Laptops, fancy cameras, drones — leave them home.

02

Hair dryers and straighteners — hotels supply these.

03

Heels, dress shoes, fancy clothes — nobody dresses up.

04

Five novels — your phone holds a library.

05

A suitcase larger than 21 inches — it will not be your friend.

06

Anything you'd be heartbroken to lose.

Air travel regulations

TSA in 30 seconds.

The rules change. Always check tsa.gov in the days before your flight. The 30-second version:

Liquids: 3-1-1

Containers of 3.4 oz (100 ml) or smaller, in one quart-size clear plastic bag, one bag per traveler.

Medications: declare

All forms allowed once screened. Liquids over 3.4 oz are fine — declare to the officer at the checkpoint and have a script or doctor’s note ready.

Always prohibited

Fireworks, flares, flammables (matches, lighters), firearms, ammunition, hazardous materials. Sharp objects (large nail clippers, scissors over 4″) must be checked.

Carry-on dimensions

Standard: 22″ × 14″ × 9″. Personal item: 18″ × 14″ × 8″. We strongly recommend a 21″ for inner-airport flexibility.
