What to pack for your first international trip: a checklist

For your first international trip, pack the documents first: a passport with enough time left for your destination’s rules, any visa or travel authorization it asks for, travel insurance, and copies. Then two cards and a little local cash, an eSIM or a roaming plan, a plug adapter, and your medication in its box, all in your carry-on.

The story

It’s the night before your first trip abroad, a week in Lisbon, and everything you own seems to be on the bed. You start with what you can’t buy there. The passport goes into a zipped pouch; you checked its dates months ago, because Portugal, like the rest of the Schengen area, asks for at least three months left on it after the day you leave, and a new one takes weeks. The printed insurance policy, your return ticket, and the address of the first night go in with it. You take a photo of the passport’s photo page and save it where you can open it offline.

Then the money: two cards, one in your wallet and one in an inner pocket of your backpack, so losing one doesn’t stop the trip. This week you checked your bank’s app, and what it charges abroad. A few euros in cash will cover the first day. On your phone, an eSIM for Portugal is already installed, ready to switch on when you land.

The plug adapter goes in with the chargers: Portugal’s sockets take round two-pin plugs (types C and F), at 230 V. Your phone and laptop chargers are marked 100 to 240 V, so the adapter is all they need. The hair straightener works only at your home voltage, so it stays home.

Your carry-on gets everything you can’t do without: the pouch, the cards, your medication in its box with the prescription, the chargers, and the power bank, which isn’t allowed in checked bags anyway. A change of clothes goes in too, in case your suitcase is late, with a sweater on top. The liquids fit in one clear bag, no bottle over 100 ml.

At security, the clear bag goes through in a tray of its own. The flight is overnight, and around three in the morning the cabin turns cold; out comes the sweater. In Lisbon, the passport officer takes a photo and your fingerprints for the EU’s new Entry/Exit System, asks where you’re staying, and waves you through. There’s no stamp. By the time your suitcase comes around on the carousel, your phone has signal.

A first trip abroad comes down to a few things you can’t replace when you get there: documents, money, a phone that works, and your medication. Pack those first, in your carry-on, then the clothes for the weather.

What to pack for your first international trip

Pack the documents and the things you can’t replace first, in your carry-on, then the clothes.

Documents

A passport with enough time left: some countries ask for six months after your trip, and the Schengen area asks for at least three months after the day you leave.
A visa or travel authorization, if your passport needs one where you’re going: check on the official sites listed in Good to know.
Travel insurance with medical cover: the policy number and the emergency phone line, on paper and on your phone.
Your return ticket and the address of your first night: border officers may ask to see them.
A vaccination certificate, if your destination asks for one: check its entry rules.
Copies of your passport’s photo page and your insurance: a photo you can open offline on your phone, and a paper copy kept apart from the originals.
One last check at the door, item by item: passport, cards, phone, and keys. In Wayboard, the Don’t forget card keeps the documents in sight, and the Final check goes through them one by one.

Money

Two cards, a debit card and a credit card, kept in different places: if one is lost or blocked, the other still works.
A little cash in the local currency: enough for the first day’s bus, coffee, and tips.
Your bank’s app, checked before you go: some banks still ask for a travel notice, and fees for spending abroad vary from bank to bank.

Phone and power

An eSIM for your destination, or your carrier’s roaming plan, set up at home: an eSIM needs a phone that supports it and isn’t locked to a carrier.
Offline maps and your bookings saved on your phone, in case you land without signal.
A plug adapter for the sockets where you’re going.
Chargers marked 100 to 240 V: they need only the adapter. A hair dryer or straightener made for a single voltage stays home.
A power bank, in your carry-on: power banks aren’t allowed in checked bags.

Health

Your medication in its original box, with the prescription, a few days’ extra, and the generic name written down: flights get delayed, and brand names change from country to country.
A few basics for the first night: painkillers, adhesive bandages, and something for an upset stomach.

Your carry-on

Everything above that you can’t replace: documents, cards, medication, chargers, and the power bank.
A change of clothes and a toothbrush, in case your suitcase arrives late.
Liquids in containers of 100 ml or less, in one clear, resealable bag of up to a liter.
A sweater or light jacket for the plane: cabins can get cold on long flights.

Clothes

Clothes for the weather where you’re going, in the month you go, in layers you can combine: the blog has lists for places like Lisbon and Porto in spring and Paris, Rome, and Barcelona in summer.
Shoes you’ve already walked in: a first trip means long days on foot.

Good to know

Passport: check the expiry date as soon as you start planning. For the Schengen area, it must be valid at least three months after the day you leave and issued within the last 10 years, says Your Europe (checked September 30, 2026). A new US passport takes 4 to 6 weeks of routine processing, plus up to 2 weeks of mail each way, says travel.state.gov (checked September 30, 2026).
Entry to Europe: ETIAS, the EU’s new travel authorization for visitors from visa-exempt countries, isn’t running yet, and the EU will announce its start date months ahead; check the official ETIAS site (checked September 30, 2026). The Entry/Exit System has been fully running at the Schengen area’s external borders since April 10, 2026: on your first entry, officers take a photo and your fingerprints, and passports are no longer stamped, says the EU’s EES guide (checked September 30, 2026).
The US, the UK, and Canada: travelers from Visa Waiver Program countries, such as the UK and Australia, need an approved ESTA before they fly to the US, says esta.cbp.dhs.gov (checked September 30, 2026); if your country isn’t on the program’s list, check whether you need a visa. Most visitors to the UK need an ETA or a visa; an ETA costs £20, and the decision usually comes within a day, says GOV.UK (checked September 30, 2026). Most visa-exempt travelers flying to Canada need an eTA, which costs CAN$7 and is usually approved within minutes, says canada.ca (checked September 30, 2026). For other destinations, check with the country’s embassy, as travel.state.gov advises (checked September 30, 2026). Apply only on official sites: others add their own fees.
Liquids: in the cabin, each container holds 100 ml (3.4 oz) or less, all in one clear bag of up to a liter, and medicines and baby food are exempt, says Your Europe (checked September 30, 2026). Some airports with newer scanners allow more, so check every airport on your route, including the way back, as GOV.UK advises (checked September 30, 2026).
Medication: some prescription and over-the-counter medicines that are legal at home are illegal in other countries, so check your destination’s rules and carry copies of your prescriptions, as travel.state.gov advises (checked September 30, 2026).
Insurance: US health insurance, Medicare and Medicaid included, usually doesn’t cover care abroad, says the same checklist (checked September 30, 2026). Travel medical insurance covers emergencies and, depending on the policy, a medical evacuation.
Money: when a card machine or cash machine offers to charge you in your home currency, you can choose the local currency instead, which often works out cheaper.
