Most family travel stories that end badly didn’t start at the airport. They started two weeks earlier, when a small detail was missed — an expired passport, a vaccine certificate left at home, an unblocked card, an insurance policy that didn’t quite cover what it was supposed to.
This guide is the checklist that prevents most of those stories. It assumes international travel with children, but the structure works for any trip that involves more than one person and more than a hotel stay.
Three weeks out: documents and bureaucracy
Most of what goes wrong on trip day is set in motion now.
Check every passport’s expiry date. Many countries require six months of validity beyond the date of return. A passport that expires three months after your return is not valid for entry in dozens of countries. Renewing one takes weeks; renewing a child’s takes longer.
Check whether you need a visa or travel authorisation. This includes ESTA for the US, ETIAS for Europe (now in force), and ETA for the UK. These are quick to apply for, but they require lead time and the children need their own.
Confirm vaccinations. Some destinations require proof of specific vaccines for entry, and children’s vaccines need to be on a different schedule than the parents’. Travel clinics get fully booked in peak season; book the appointment now.
Set up travel insurance. Read the medical coverage limits, the activity exclusions (if your kids will be doing anything not in a hotel pool), and the trip cancellation terms. Pay attention to pre-existing condition clauses. Better policies cost a little more — the difference matters precisely once, and that’s the only time it’ll matter.
Take photos of every document. Passports, ID, vaccination cards, insurance policy summaries, prescriptions. Store them somewhere accessible offline — a phone album, an encrypted file, or with a service that keeps documents available without internet (this is one place where having a digital assistant that stores your documents earns its keep).
Two weeks out: money and connectivity
Tell your bank you’re travelling. Most cards no longer require this, but some still do. The fix is two minutes; the consequence of skipping it is a blocked card in a foreign country with three crying children at a taxi rank.
Set up an eSIM or activate roaming. Roaming charges can be brutal. eSIMs from Airalo, Holafly, or Saily give you data in most countries for a fraction of the cost. Set them up before you leave — most activate in minutes but require a working connection.
Withdraw a small amount of local currency. Not for everything — most places take cards — but for taxis, tips, and emergencies. Airport exchange rates are punishing; do it at your bank.
Save offline maps and translation apps. Google Maps offline maps for your destination, Google Translate offline language pack, and a local taxi app installed and tested. The first ride from the airport is not the time to find out an app needs verification by SMS.
One week out: the house and the routine
This is the part travellers forget until they’re packing the night before.
Mail hold. Set it up online with the postal service. A pile of post visible from the street is one of the more reliable advertisements that no one is home.
Lights on timers. Cheap and effective. Plug a couple of lamps into mechanical timer plugs and set them for an evening cycle.
Pet, plant, and key arrangements. Confirm in writing with whoever is looking after them. Leave a printed sheet with veterinary information, watering instructions, emergency contacts, and the wifi password.
Update an emergency contact. Make sure someone who is not travelling with you knows your itinerary, your flight numbers, and the name of your accommodation. If you have an in-app travel project for your trip, share access with that person.
Adjust the kids’ sleep schedule. If you’re crossing more than three time zones with young children, start nudging bedtime by 15–30 minutes per day in the direction of the destination. It softens the first two days dramatically.
Three days out: the pack
The honest secret of family packing is this: pack lighter than you think. Most destinations sell most things. You will end up wearing the same three outfits anyway.
Clothing
- Layers, not bulk. A merino base layer plus a light insulating layer plus a waterproof shell handles almost any weather better than one heavy coat.
- One nice outfit per person. Not three. One.
- Comfortable walking shoes that are already broken in. This is the most predictable failure point on family trips. Do not start a new pair of shoes on day one.
- Swim gear if there is any chance. Hotels with pools, unexpected beaches, hot springs. It packs flat.
The toiletries kit
- A small, structured toiletry bag is worth the money. Brands like Bagsmart, Calpak, or Béis make ones that hang. They’re easier than rooting through a tote.
- Travel-size containers refilled from your own products. Most resort shampoos are bad.
- Prescription medications in original packaging, with copies of the prescriptions. Not in your checked bag.
- A small first-aid roll: plasters, paracetamol or ibuprofen, child versions if relevant, anti-diarrhoeal, antihistamines, electrolyte sachets.
The bag for the journey itself
This bag stays with you. It is not your overall hand luggage; it’s a smaller subset.
- Passports, boarding passes, the photos of documents
- One change of clothes for each child (small)
- Wet wipes and a small pack of nappies for the youngest
- Snacks that aren’t sticky and aren’t loud (apple slices, breadsticks, crackers, dried fruit)
- A refillable water bottle for each person, empty through security
- Wired headphones for the kids — most planes only have wired jacks
- Downloaded films and audiobooks (download them the night before, on home wifi)
- Phone chargers, a power bank, a multi-plug travel adapter
What goes in the main suitcase
If it’s not on this list, ask whether the destination has shops. They almost certainly do.
- The clothes, in packing cubes if possible. Packing cubes are the one travel gadget that’s worth it.
- Spare prescription medications
- Camera or anything fragile, wrapped in clothing
- Empty space for what you’ll buy
What doesn’t go in the suitcase
- Power banks (must be in hand luggage on most airlines)
- Lithium batteries beyond the airline’s stated limit
- Liquids over 100ml if you’re not checking the bag
- Anything sharp
- Anything irreplaceable
The day before
The point of preparation is that the day before should be calm.
Re-confirm. The hotel reservation, the airport transfer, the seat assignments. A surprising number of these change at the last minute and getting a polite email about it the day before beats finding out at check-in.
Charge everything. Phones, tablets, headphones, power banks, cameras. All of them.
Print backup paper copies of the first hotel reservation and any document you’d need at immigration. Phones run out of battery at the worst times.
An early night. This is the cheapest and most ignored travel advice in existence.
The day of
The day-of list is short, because if the rest of the list was followed, today is mostly execution.
- Leave for the airport with two and a half to three hours buffer for international.
- Carry a printed photo of each child showing what they’re wearing today. If anyone gets separated in an airport, this saves time.
- Drink water on the plane. Far more water than feels necessary.
- The first thing you do on arrival, before anything else, is buy water and snacks. Hangry travellers make terrible decisions about the rest of the trip.
A final note
The work of preparation feels excessive when you’re doing it. It feels worth it the moment something doesn’t go wrong — when the connection is tight but you’re already at the gate, when a child needs a plaster and you have one, when you arrive and the eSIM is already working.
Most family travel stress is preventable. The prevention happens in the three weeks before the trip.
