International trips come with a longer to-do list than most of us realise.
There are the obvious things, like checking your passport and packing your clothes. Then there are the things you might only remember at the last minute: travel insurance, an adapter, mobile data, copies of your documents or a card that works in another country.
So, instead of trying to keep all of that in your head, use this international travel checklist to work through it before you leave.
It covers your travel documents, health and insurance, packing, phone and connectivity, and money, so you can check each one off as you prepare.
What travel documents do you need for an international trip?
Your passport is the obvious one, but there may be several other documents you need before you can travel.
Start by checking the entry requirements for your destination based on your nationality. Some countries allow visa-free visits, while others require a visa or electronic travel authorisation before arrival. Your passport may also need to remain valid for a certain period beyond your travel dates.
Do this early rather than assuming you can sort everything a few days before your flight. Depending on the destination, getting the right visa or travel authorisation can take time.
Before you travel, check that you have:
- A valid passport
- The visa or travel authorisation required for your destination
- Flight confirmations and your itinerary
- Accommodation confirmations
- Proof of onward or return travel, if required
- Any additional documents requested at immigration
- Digital or paper copies of important documents
It’s a good idea to keep copies of your passport, visa and other important documents somewhere separate from the originals. Having digital copies you can access from another device can also be useful if your phone or physical documents are lost.
If your journey includes a connection in another country, check its transit requirements too. Depending on your nationality and itinerary, you may need additional documentation even if you’re only changing planes.
What health and insurance preparations should you make?
Nobody wants to spend the weeks before a holiday thinking about getting sick. Still, a little preparation here can make a big difference if something does happen while you’re away.
Check the health requirements and recommendations for your destination well before departure. Depending on where you’re travelling, you may need certain vaccinations or proof of vaccination to enter.
The World Health Organization provides travel health information, but you should also check official guidance for your destination and speak to a healthcare professional if you have questions about vaccinations or medication.
Add these to your checklist:
- Check vaccination requirements and recommendations
- Arrange travel insurance
- Pack enough prescription medication for your trip
- Keep medication in its original packaging where possible
- Bring copies of prescriptions or supporting medical documents if needed
- Check whether your medication is restricted at your destination
- Save your travel insurer’s emergency contact details
Travel insurance is also worth arranging before you leave. Policies vary, so check what yours actually covers, particularly medical treatment, cancellations, delays and lost belongings.
If you take prescription medication, don’t assume you can simply buy more when you arrive. Rules around medication vary between countries, and some medicines that are commonly available at home may be controlled elsewhere.
What should you pack for international travel?
Packing depends heavily on where you’re going and what you’ll be doing there, but there are a few essentials that belong on almost every travel checklist for international travel.
Start with what you’ll genuinely use rather than trying to prepare for every possible scenario. Check the weather forecast shortly before you pack and think about your plans for each day. A beach holiday, work trip and week of hiking obviously call for very different suitcases.
For the basics, check off:
- Clothes appropriate for the weather and your plans
- Comfortable shoes
- Toiletries
- Prescription medication
- Phone and other devices
- Chargers and cables
- A travel adapter for your destination
- Headphones
- Reusable water bottle, if useful for your trip
- Any destination-specific essentials
Your carry-on deserves its own mini checklist. Keep anything difficult or expensive to replace with you rather than putting it in checked luggage.
That includes:
- Passport and travel documents
- Wallet and cards
- Phone
- Medication
- Valuables
- Chargers
- A change of clothes and basic toiletries
If your checked bag is delayed, having the essentials with you can make the first day of your trip considerably easier.
And check your airline’s baggage rules before packing. Cabin bag dimensions, weight allowances and restrictions can vary between airlines and ticket types.
How can you stay connected while travelling abroad?
Working out how you’ll get online is much easier before you arrive than after you land and discover your usual mobile plan charges a small fortune for roaming. International roaming is one option, and for short trips it may be convenient. But depending on your mobile provider and destination, it can be expensive.
A local SIM is another option. You can usually buy one at the airport, a mobile shop or convenience store after arrival, although you may need to show identification and physically swap your existing SIM.
If your phone supports it, an eSIM gives you another option. It’s digital, so there’s no physical SIM to insert or remove. You can buy a data plan for your destination and set it up on your phone, sometimes before you even leave home.
Before travelling, check:
- Your mobile provider’s international roaming rates
- If your phone is unlocked
- Which phones support eSIM
- How much data you expect to use
- Coverage at your destination
- That your eSIM or roaming plan is ready before arrival
If you’re an iPhone user, you can also check how to activate an eSIM on iPhone before your trip. It’s worth downloading anything important while you still have reliable Wi-Fi too. Save your boarding passes, accommodation details, maps and transport information offline where possible.
That way, you’re not completely dependent on finding airport Wi-Fi the moment you arrive.
How should you manage money when travelling abroad?
Money deserves a little more planning than simply checking that there’s enough in your bank account.
Before travelling, think about what currency you’ll need, how you’ll pay for everyday purchases and what you’ll do if your main payment method doesn’t work.
Start with:
- Check the local currency at your destination
- Find out how widely cards are accepted
- Check your card’s foreign transaction and currency conversion fees
- Make sure your card can be used internationally
- Have a backup payment method
- Keep a small amount of local cash if useful
- Check ATM fees and withdrawal limits
- Avoid keeping all your cards and cash in the same place
Having a card that works abroad can make everyday spending easier, particularly if you’re travelling between countries or paying in different currencies.
It can also be useful to hold multiple currencies rather than converting money every time you need to make a payment. With Grey, you can hold supported currencies in your account and use your Grey Card for international payments.
Before paying, always check which currency you’re being charged in. Some shops, hotels and ATMs may offer to convert the transaction into your home currency. The rate offered may differ from the rate your card provider would use, so check the amount and conversion before accepting it.
Your card can also be useful before the trip itself. From booking activities to paying on international sites, having an international payment method gives you more flexibility when arranging things in advance.
It’s still sensible to travel with a backup. Keep another card or some emergency cash somewhere separate from your main wallet so one lost wallet doesn’t leave you without access to money.
Your international travel checklist before you leave
A few days before your trip, do one final run-through.
- Passport is valid and packed
- Visa or travel authorisation is approved
- Flights and accommodation are confirmed
- Important documents are saved offline
- Travel insurance is active
- Medication is packed
- Clothes and essentials are ready
- Travel adapter and chargers are packed
- Roaming, SIM or eSIM is sorted
- Offline maps and important information are downloaded
- Your main card works internationally
- You have a backup way to access money
- You have any local cash you want to carry
You don’t need to prepare for every possible thing that could happen while you’re away. The aim is simply to take care of the things you can sort in advance, so you’re not trying to solve them from an airport terminal or hotel lobby.
Frequently asked questions about preparing for international travel
What should be on an international travel checklist?
Your international travel checklist should cover your passport and other travel documents, visas, health requirements, travel insurance, medication, clothing, chargers and adapters, phone connectivity and how you’ll access and spend money abroad.
You can also add destination-specific items based on the weather, activities you have planned and local entry requirements.
What documents do I need for international travel?
At a minimum, you’ll need a valid passport. Depending on your nationality and destination, you may also need a visa or travel authorisation, proof of accommodation, a return or onward ticket and other supporting documents.
Always check the official entry requirements for your destination before travelling.
Should I get travel insurance for an international trip?
Travel insurance can help cover unexpected costs related to medical treatment, cancellations, delays, lost luggage and other problems, depending on your policy.
Read the terms carefully before buying so you know exactly what is and isn’t covered.
How do I get mobile data abroad?
You can use international roaming from your existing mobile provider, buy a physical SIM at your destination or use an eSIM if your phone supports one.
Compare the cost, data allowance and coverage of each option before choosing.
What is the best way to spend money abroad?
The best option depends on your destination and how you prefer to pay. A card that supports international payments can be useful for everyday purchases, while a small amount of local cash can help in places where cards aren’t accepted.
It’s also a good idea to have a backup payment method and check any currency conversion or international transaction fees before travelling.
How early should I prepare for an international trip?
Start checking passport validity, visa requirements and vaccinations as soon as you know where you’re travelling, as some applications and health preparations can take weeks or longer. Packing, connectivity and spending arrangements can usually be handled closer to departure, but sorting them a few days in advance gives you time to fix any problems.
With the practical details taken care of, there’s one less thing competing for your attention when your trip begins.
