The First-time Traveller (2 of 3)

The three things you can't fake

People burn weeks on gear and packing cubes and forget that a trip only actually requires three things. A valid passport, reliable access to money, and a ticket, or proof you're leaving the country you're entering. Miss one and you don't board. Nail all three and everything else is a preference, not a requirement.

• A passport valid for at least six months past the date you fly home. Airlines and border agents check this, and 'it expires in four months' can get you turned away at check-in.
• Money you can actually reach abroad: a debit card that works in foreign ATMs, a backup card on a different network, and a little cash.
• A ticket, or proof of onward travel. Some countries won't let you in without evidence you're leaving.

That's the whole non-negotiable list. Here's the detail on each.

Your passport is the one thing you can't replace fast

Everything else on a trip is buyable or borrowable. A passport isn't, not quickly. Lose it in a small town and you're looking at a trip to the nearest embassy and a few days of your itinerary gone. So treat it like the valuable it is.

Before you leave, check the expiry date and count six months past your return. Renew now if it's close, because processing runs weeks. Flip through and make sure you've got blank pages for stamps and visas. Photograph the ID page, email it to yourself, and write the number somewhere separate from the book.

On the road, keep it in a money belt or the zipped inner pocket of a bag that stays on you, not loose in the daypack you set down at cafes. Don't hand it to a hostel to 'hold' unless you trust the lockbox. If it does go missing, call your embassy the same day. Emergency travel documents usually come through in a few days, so it's a hassle rather than a catastrophe, but only if you move fast.

Money: it's about access, not a fat wallet

You don't need to carry a brick of cash. In 2026 an ATM card and a phone cover most of it. What you need is reliable access and a backup for when the primary fails, because it will fail eventually, usually on a Sunday in a town with one broken machine.

Carry two bank cards on different networks, one Visa and one Mastercard, stored in separate bags so a single theft doesn't strand you. Pick a card with no foreign-transaction fee and free international withdrawals; over a few months that difference is real money. Tell your bank you're leaving so the first purchase in Bangkok doesn't trip a fraud lock. A low-fee account like Wise is worth setting up if you're gone a while. And keep $200-500 in USD or euros hidden separately for the day the cards don't work.

Most of your money should stay in your account at home, paying whatever bills follow you, while you pull out small amounts as you go. The cash on your body is always a fraction of what you're actually managing.

The ticket, and the onward-travel trap

Getting a ticket is the easy part now. The thing that catches first-timers is the onward-travel rule.

You have options on how to fly it. A true round-the-world fare makes sense if your route runs one direction around the globe with a few long hauls, since it locks your biggest cost up front. Booking legs separately or as open-jaw tickets, into one city and out of another, is often cheaper and more flexible. And you only strictly need your first flight booked to leave; later legs can wait, though booking ahead usually saves money. If you want the multi-stop version priced properly, that's what AirTreks does.

Here's the trap. Plenty of countries want proof you're leaving before they let you in, and airlines can refuse to board you without it. A booked onward flight covers it. So does a cheap outbound bus or budget flight, or in some cases a travel-insurance document showing repatriation. Check the entry rules for each country before you show up at the gate.

The stuff that supports the big three

Past passport, money, and ticket, a short list of things earns its weight. Health paperwork first: proof of any required vaccinations, your prescriptions in their original bottles, and a one-line medical summary if you've got a condition a foreign doctor would need to know about. Travel insurance, with the policy number saved offline, because a hospital in another country is the one bill that can end your trip financially. And copies of your passport, visas, and insurance, kept separate from the originals and backed up in the cloud.

For medications, bring your prescriptions plus a small kit for the boring stuff: something for diarrhea, pain relief, an antihistamine, and malaria pills if your route calls for them. Gear-wise, the real minimum is a backpack, clothes for the climates you're hitting, toiletries, a phone and charger, and basic first aid. Everything beyond that is optional, and you'll figure out what you actually reach for by week two.

What not to do

Don't keep your passport in the outer pocket of your daypack, and don't leave it lying in a room where housekeeping or a dorm-mate can pocket it. Use the money belt. Don't travel on a single card; the day it gets swallowed or frozen you'll understand why. Don't stash all your cash in one place either. Split it.

Don't convince yourself you need expensive gear to pull this off. Don't pack a bag full of 'just in case' items you'll carry for months and never touch. Don't take original documents when a copy does the job, and leave the jewelry, the good camera, and the spare gadgets at home.

The bottom line

Round-the-world travel comes down to three things: a passport that's valid, money you can reach, and a ticket. Get those sorted and you can leave tomorrow. Everything else is optimization.

And optimization has a cost. Overpreparing makes trips worse, not better, more weight on your back and more to keep track of. Start with the essentials, go, and let the trip teach you the rest.

FAQ

• Do I need visas sorted before I leave? Depends on your passport and route. Many countries do visa-on-arrival or an online e-visa, so you don't need every one in advance. Check each country you're entering, and get ahead on the ones that take weeks - India and some African nations are the usual slow ones.
• What if my card gets swallowed by an ATM? It happens. Use your backup card, then call the issuer to cancel the trapped one. This is exactly why you carry two on different networks plus some emergency cash.
• Is a round-the-world ticket cheaper than booking flights myself? Not always. Piecing together budget carriers and open-jaws often beats a RTW fare, especially in Asia. A RTW or multi-stop fare wins when you've got several long-haul legs and want the cost fixed up front. AirTreks will price the multi-stop version if you want a number to compare.
• How much cash should I actually carry? Enough for a day or two, plus a hidden $200-500 emergency stash. Pull larger amounts from ATMs less often to cut per-withdrawal fees, and don't walk around with weeks of budget in your belt.
• Do I really need travel insurance? Yes. It's one of the cheapest things you'll buy and the only one that stops a medical emergency from bankrupting the trip. Get a policy that covers evacuation.
• My passport expires in five months. Am I fine? Probably not. A lot of countries require six months' validity beyond your entry or return date, and airlines enforce it at check-in. Renew before you go.
