The gap between stepping off the plane and reaching your bed is where most travel stress lives. You're tired, possibly jet-lagged, and suddenly need to make decisions in a place that runs on different rules. None of it is hard once you know the basics — here's what's worth sorting out for every destination.
Emergency numbers
The first thing to look up, and the thing you most hope to never use. There's no universal number, though a few cover huge areas: 112 works across the EU and much of the world from any phone, 911 in North America, 999 in the UK. Emergency calls usually connect even with no SIM and no credit. Save your destination's number before you go.
Tipping norms
Tipping is pure local custom, and getting it wrong cuts both ways — under-tip in the US and you've genuinely shortchanged someone; over-tip in Japan and it can read as odd. Rough map:
- US / Canada: 15–20% expected at restaurants, plus tips for bars, taxis, and hotel staff.
- Much of Europe: service often included; round up or leave 5–10% for good service.
- Japan, South Korea: generally no tipping — it can even cause confusion.
Plugs & voltage
Two separate things to check. Plug shape decides whether your charger physically fits (Type A/B in the Americas, C/E/F across Europe, G in the UK, and so on). Voltage decides whether it's safe to plug in — most of the world runs 220–240V, North America runs 110–120V. Phone and laptop chargers are almost always dual-voltage (check for "100–240V" on the brick), so you just need a plug adapter. Hair dryers and other heating appliances are the ones that can fry, so leave them home.
Currency & rough conversions
Know the currency and a mental shortcut before you arrive so you're not doing long division at a market stall. Pick a round anchor — "10 euros is about 11 dollars," or "1,000 yen is roughly 7 dollars" — and you'll spot a rip-off instantly. A couple of habits help everywhere: pay in the local currency, not your home one, when a card terminal offers the choice (the "convenience" rate is worse), and prefer ATMs over airport exchange counters.
One offline trick: note today's exchange rate before you fly. Rates barely move day to day, so a number saved on your phone is plenty accurate for mental math — no data needed.
Airport to city
Most airports have a cheap, well-marked public option — a train, metro, or official airport bus — running right alongside the taxi rank. It's usually a fraction of the cab fare and often faster in traffic. The classic trap is the unofficial "taxi" tout who approaches you inside the terminal; always use the marked rank or a known ride app. Look up your route before you land so you can walk straight past the chaos.
SIM & eSIM basics
If you do want data, you've got options:
- eSIM: a data plan you buy and activate online before you even land — no physical card, no shop. The fastest route if your phone supports it (most recent phones do).
- Local SIM: bought at the airport or a shop on arrival. Often the cheapest for longer stays, but needs an unlocked phone and a few minutes to set up.
- Carrier roaming: zero setup, but typically the priciest by far. Fine for a quick trip, painful for a long one.
And if you'd rather not bother at all, that's exactly what offline tools are for — your map, guide, and essentials work whether or not you ever buy a megabyte.
