All 24 travel hacks

Connectivity

• Your phone and laptop chargers are almost certainly dual-voltage. Look for '100–240V' printed on the brick; they work anywhere with just a plug adapter, no bulky converter. Check plugs & voltage →
• Set up a travel eSIM before you leave. It activates the moment you land, so you skip roaming fees and the airport-wifi scramble. Find an eSIM →
• Most travel data goes to maps and messaging, not video. Light use runs about 0.15 GB a day, so estimate before you buy and avoid overpaying. Estimate your data →
• Download an offline map of your destination before you fly. It gives you turn-by-turn navigation with zero data and zero signal.

Documents

• Airlines check your entry eligibility before they let you board, not just immigration on arrival. A missing eTA can strand you at your home airport. Check visa rules →
• Many 'visa-free' countries still require your passport be valid at least 6 months beyond your trip. Check the expiry date, not just the visa. Check visa rules →
• An eTA (like the US ESTA) is not a visa. It's a quick online pre-authorization, but you still have to get it before you fly, not on arrival. Visa types explained →
• Email yourself a photo of your passport's photo page. A copy dramatically speeds up a replacement if the original is lost or stolen.

Power

• A plug adapter only changes the shape. It does nothing to the voltage, so a single-voltage hair dryer can still fry on 230V even with an adapter. Adapter vs converter →
• A single Type C adapter covers most of Europe, Asia, and Africa. It's the most common plug on Earth, used in around 127 countries. Plugs by country →

Money

• When a card machine abroad asks whether to charge in your home currency or the local one, always pick local. 'Home currency' hides a padded exchange rate.
• In the world's cheapest countries your money goes 5–6× further than at home. Where you go often matters more to the budget than how you fly. Cheapest countries →
• Tell your bank your travel dates, or carry a card with no foreign-transaction fees. A card frozen on day one can derail a trip.

Jet lag

• Flying east is harder than flying west. Your body clock naturally runs a little long, so it delays westward more easily than it advances eastward. Plan your jet lag →
• Chase morning light after flying east, and evening light after flying west. Timing your light exposure shifts your body clock faster. Beat jet lag →
• Set your watch to destination time the moment you board. Thinking in local time early makes the whole adjustment easier.

Packing

• Roll clothes instead of folding. It fits more into the same space and leaves fewer creases.
• Pack one full change of clothes in your personal item. If a checked bag goes missing, you won't be stuck in yesterday's outfit. Build a packing list →
• The carry-on liquids limit is per container, not per bag. A large bottle fails screening even if it's nearly empty.

Logistics

• Screenshot your booking confirmations and boarding passes. You can't always count on signal or battery at the moment you need them.
• When you book across time zones, double-check the date, not just the hour. A red-eye can quietly land you a day later than you expected. Convert time zones →
• Set a daily budget before you go, not after. Knowing your daily number keeps a long trip from surprising you at the end. Estimate a trip budget →

Health

• Tap-water safety varies enormously by country. When you're unsure, stick to sealed bottled or boiled water, and check before you even brush your teeth.
• Move and hydrate on long flights, and go easy on alcohol. Cabin air is dry, and dehydration makes jet lag worse.
