This one is organised around what actually goes wrong, and it leads with the thing most travellers haven’t caught up on: European border rules changed in 2026, and they change again before the year is out.

The 2026 changes worth knowing about

Europe’s borders went biometric

The EU’s Entry/Exit System (EES) replaces passport stamping for non-EU travellers with a digital biometric record: facial scan, plus fingerprints for anyone aged 12 or over. France switched from pilot to full operation at its external borders in April 2026, and other member states are following.

The practical consequence is queue time. First registration takes longer than a stamp did, and the busiest crossings (Paris CDG, Frankfurt, Madrid Barajas, Rome Fiumicino, Athens) are where that shows up worst. If you’re connecting through one of those on a tight transfer, build in more margin than you’re used to.

ETIAS is coming, and it isn’t a visa

ETIAS is a pre-travel authorisation for visa-exempt visitors to the Schengen Area, closer to the US ESTA than to a visa. Current guidance points to the last quarter of 2026, at around €20, valid roughly three years or until your passport expires.

One honest caveat: ETIAS has been postponed repeatedly. Anyone telling you a firm date with confidence is guessing. Check the official EU ETIAS pages before a trip rather than trusting a blog, including this one, which will go stale.

Airport security is slowly getting less annoying

Newer CT scanners mean some airports no longer require you to remove shoes or unpack laptops, and there’s movement toward relaxing the liquid limit. Rollout is uneven, so the 100ml rule still applies in most places. Pack for the strict version and enjoy it when you’re waved through.

Before you book

Check passport validity properly. Many countries require six months’ validity beyond your return date, and some count from entry rather than exit. This is the single most common reason people are refused boarding, and it’s entirely preventable.

Check whether your destination needs an onward ticket. Several countries require proof you’re leaving. Airlines enforce it at check-in because they carry the cost of flying you back.

Book the insurance when you book the trip, not the week before. Cancellation cover only works if it’s in place before the thing you’re cancelling for happens. Buying it the night before departure means you’ve paid for a fraction of what you could have had. The reasoning is in our travel insurance guide.

Before you fly

Sort connectivity on the ground, not in the terminal. Install and activate a travel eSIM before you leave, while you’re on wifi you trust. Installing one on airport wifi with 4% battery is a bad time. Which one depends on where you’re going, because providers resell different local carriers in different countries. That’s the whole argument in our eSIM guide.

Tell your bank, and carry a second card on a different network. Blocked cards are the most common day-one problem, and Visa and Mastercard acceptance genuinely differs by country. Keep the backup somewhere separate from your wallet.

Test your VPN before you need it. If you’re going somewhere with heavy internet filtering, install and verify it works while you’re still home. Provider websites are frequently blocked once you land, which makes fixing it there considerably harder. More in our VPN guide.

Photograph your documents. Passport, insurance policy number, and any visa, stored somewhere you can reach without your phone. An email to yourself works. If the phone goes, you still have them.

At the airport

Arrive 2–3 hours before international departures and 1.5–2 hours domestic, and add margin at EES-affected European borders while everyone adjusts to the new system.

Beyond that, the classics genuinely do work: liquids at the top of the bag, electronics reachable, shoes you can get off without sitting down. None of it is clever, all of it saves minutes when you’re short of them.

One that isn’t obvious: if your flight is disrupted, get in the phone queue and the desk queue simultaneously. The phone line is often faster, and if the desk reaches you first you simply hang up. People lose hours choosing one.

On the plane

Change your watch to destination time at the gate, not on landing. This is the highest-leverage jet lag habit and it costs nothing. Once your devices show destination time, you start making decisions on that schedule (sleeping, eating, declining the coffee) instead of doing the mental arithmetic and getting it wrong.

Treat cabin wifi as a hostile network. Same as hotel and airport wifi. It’s fine for browsing; it’s a poor place to log into a bank without protection.

Hydrate more than feels necessary, move every couple of hours on long-haul, and don’t count on sleeping if you can’t normally sleep sitting up. Plan the first day around being tired rather than pretending you won’t be.

On arrival

Always pay in the local currency. When a card terminal or ATM offers to charge you in your home currency, decline. That option hands the exchange rate to the merchant’s processor, and it’s reliably worse than your bank’s. This one habit saves more than most card-switching decisions. Details are in our travel money guide.

Withdraw from a bank ATM, not an airport bureau. Airport exchange desks have the worst rates you’ll encounter, because they’re selling convenience to people without alternatives.

Take small amounts of cash. Card acceptance is near-universal in some countries and patchy in others. Enough for a taxi and a meal is usually right.

The things that actually ruin trips

Not the ones the listicles focus on. In rough order of how much damage they do:

• A medical problem without adequate cover. The tail risk (hospital treatment abroad and, at worst, a medically supervised flight home) is the only catastrophic item on this page.
• An uninsured scooter accident. Standard policies exclude motorcycle and scooter use, often unless you hold a specific licence category. Renting one for an afternoon is among the most common ways travellers discover they aren’t covered.
• An undeclared pre-existing condition. Declaring may raise the premium. Not declaring can void the entire policy, including for something unrelated.
• No way to communicate. Everything is harder without data. It’s also the cheapest of these to solve.
• A single card that gets blocked. Preventable in about two minutes before you leave.

Three of those five are insurance, and that’s not an accident: it’s the category people research least and the one where being wrong costs most.

The short version

Sort four things before you fly: data that works when you land, a card that doesn’t tax every purchase, access to your own services from abroad, and cover for the day something goes properly wrong.

That’s the whole setup, and it’s on one page: our travel tech stack.

Border rules, fees, and policy terms all change, the EES and ETIAS timelines above especially. Where we quote a figure we date it, and we say where it came from. That standard is set out in how we test. If you spot something that’s gone stale, tell us.
