The 25 Most Important Travel Tips I Wish I Had Known Earlier

I have made most of the mistakes on this list. Some of them I made twice. The passport that almost expired mid-trip. The credit card blocked in Lisbon because I forgot to notify the bank. The Madrid airport hotel I booked thinking it was close to the terminal — it was close, but on the wrong side of the runway, a 45-minute taxi ride away. Travel rewards experience, but the tuition is paid in small disasters. Here are the 25 tips that would have saved me the most trouble, organized by when you need them.

Before You Leave

1. Check your passport expiration the day you start planning

Most countries require your passport to be valid for at least six months beyond your entry date. Get this wrong and you can be denied boarding at the airport, or turned away at immigration even with a valid visa. I check my passport expiration the day I book a flight, not the week before. Routine U.S. passport renewal currently takes 8 to 11 weeks. Expedited service (2 to 3 weeks) costs an extra $60. If you are reading this three weeks before your trip and your passport expires in five months, you need expedited service today, not next week.

2. Buy travel insurance — and read the exclusions

Travel insurance is the most skipped essential in travel planning, and it is the one I will not travel without anymore. A basic policy costs 4 to 8 percent of your total trip cost. It covers medical emergencies abroad (which can run into tens of thousands of dollars — a hospital stay in Tokyo averages $4,000 per day), trip cancellation, lost luggage, and flight delays. Before you buy, read the exclusions carefully. Most policies do not cover “fear of travel,” pre-existing conditions unless declared, or injuries from adventure activities without a rider. World Nomads, Allianz, and SafetyWing are reliable starting points. The cheapest policy is rarely the right one.

3. Email yourself scanned copies of every important document

Take photos of your passport, driver’s license, visas, vaccination records, and the fronts of your credit cards. Email them to yourself at an address you can access from any device. Store them in Google Drive or Dropbox as backup. If your wallet or passport is stolen, having these copies at an embassy or police station speeds up the replacement process dramatically. I keep a dedicated folder named “travel-backup-2026” that I update before every trip.

4. Tell your bank where you are going

If your bank does not know you are traveling abroad, they may flag your first international transaction as fraud and freeze your card. I have had this happen in Lisbon at 11 p.m. after a 9-hour flight. Most banks let you set travel notifications through their mobile app or website. Set the dates and destinations for your entire trip. Also confirm your card has no foreign transaction fees — these typically run 1 to 3 percent per purchase and add up faster than you would expect. The Chase Sapphire Preferred, Capital One Venture, and Wells Fargo Autograph are popular no-foreign-fee cards.

5. Download offline maps before you leave home

Google Maps lets you download city-sized areas for offline use. Do this for every city you will visit before your trip starts. The offline version includes driving, walking, and transit directions (though transit schedules will not update without internet). Save your hotel, key sights, and any restaurants you have researched as starred locations. If you are going to a country where Google Maps is blocked — China, for example — download Maps.me or Apple Maps offline equivalents instead. I once spent an hour lost in Kyoto because I assumed I could pull up Google Maps at the airport. The airport Wi-Fi was down.

On the Plane

6. Drink more water than you think you need

Airplane cabin humidity runs 10 to 20 percent, drier than the Sahara Desert. Dehydration is the main cause of jet lag, headaches, and the dry skin that makes you look ten years older when you land. I drink at least 8 ounces of water per hour in the air — roughly one liter for a four-hour flight. Avoid alcohol and caffeine, both of which dehydrate you further. Bring an empty water bottle through security and fill it at a water fountain before boarding. Yes, this means more bathroom trips. It is worth it.

7. Set your watch to destination time the moment you sit down

This is a psychological trick that works better than melatonin for many travelers, including me. The moment I take my seat, I set my watch, phone, and any other devices to my destination’s time zone. I start eating and sleeping on destination time as much as the flight schedule allows. If it is nighttime at my destination, I try to sleep even if it is afternoon where I took off. This accelerates jet lag recovery by up to 50 percent.

8. Get up and move every two hours

Sitting still for long periods increases the risk of deep vein thrombosis, a serious condition where blood clots form in the legs. Get up every two hours, walk the aisle, and do simple calf raises while seated. Compression socks also help — they are not just for older travelers. Flights over four hours warrant them; flights over eight hours absolutely require them. I wear them on every long-haul flight now and arrive with noticeably less ankle swelling.

9. Pack a change of clothes in your carry-on

Even if you check a bag, pack one full outfit (including underwear and socks) plus essential toiletries in your carry-on. Lost luggage affects roughly 1 in 200 passengers on international flights. If your bag is delayed, you will have a change of clothes for the next day while you wait. If your bag is lost entirely, you will have something to wear while you shop for replacements. I learned this on a flight to Rome where my bag spent three extra days in Frankfurt. I now pack a change of clothes, my medications, and my phone charger in my carry-on, every flight, no exceptions.

On the Ground

10. Carry only the cash you need for the day

Pickpocketing is a fact of life in tourist-heavy cities from Barcelona to Bangkok. Limit your exposure by carrying only the cash you will actually spend that day — usually 30 to 50 euros or equivalent. Leave the rest in your hotel safe. Distribute what you carry across multiple pockets so a single theft does not take everything. I keep 20 euros in my front pocket for small purchases and the rest in a money belt under my shirt.

11. Use a money belt for documents, not for daily spending

For passport, backup credit cards, and large cash reserves, use a money belt worn under your clothing or a hidden neck pouch. These are not fashion accessories. They are anti-theft devices. Wear them under your shirt, not visible. Yes, you will look slightly paranoid. The alternative is carrying your passport in a back pocket where pickpockets in Rome and Barcelona have a 30-second extraction time. I have watched a pickpocket in Naples lift a phone from a tourist’s back pocket in under five seconds.

12. Know the local emergency numbers

112 is the universal emergency number across the European Union. In the United States and Canada, it is 911. In Australia, 000. In Japan, 110 for police and 119 for ambulance and fire. Save these in your phone before you arrive. Note that 112 also works on most mobile phones worldwide as an emergency fallback, even without a SIM card.

13. Register with your embassy’s travel program

United States citizens can register with the Smart Traveler Enrollment Program (STEP) at step.state.gov. The embassy will email you security alerts, demonstration notices, and emergency evacuation information for your destination. Canadians can register with Registration of Canadians Abroad. United Kingdom citizens can sign up for FCDO travel advice alerts. All three are free. I have received real security alerts through STEP — most recently about a transit strike in Paris that I would not have known about otherwise.

14. Trust your instincts about situations, not about people

“Sketchy” neighborhoods often look rough but are safe. Tourist-heavy areas often look fine but attract pickpockets. Judge situations by behavior, not appearance: someone standing too close in an empty train car, someone insisting on helping you with your bag when you did not ask, someone offering a free gift that requires you to follow them. These are patterns of distraction scams, regardless of who is doing them. The most effective pickpockets in Europe are well-dressed women in their twenties, not the stereotypes you might expect.

Money

15. Withdraw local currency from ATMs, not from currency exchange kiosks

Airport currency exchange kiosks charge 5 to 15 percent in fees and offer terrible exchange rates. ATMs at the airport, or in town, almost always give you the interbank exchange rate, which is the best available. Use a debit card with no foreign transaction fees and ATM fee reimbursement (Charles Schwab and Fidelity both offer this). Always decline “dynamic currency conversion” — when a terminal offers to charge you in dollars instead of local currency, say no. The merchant’s rate is always worse than your bank’s.

16. Carry two credit cards from two different networks

Bring one Visa and one Mastercard, or one Visa and one American Express. If one network has an outage or your card is lost, you still have a backup. Discover is rarely accepted outside the United States. American Express is increasingly accepted in Europe but still lags Visa and Mastercard in Asia and Latin America. I once had my primary card declined at a hotel checkout in Marrakech because the Visa network was down. The Mastercard in my backup wallet saved the trip.

17. Research tipping customs before you arrive

Tipping expectations vary wildly. In the United States, tipping 18 to 22 percent at restaurants is expected; tipping less is insulting. In Japan, tipping is insulting — it can be refused and create an awkward scene. In France, a service charge is included by law; rounding up or leaving 1 to 2 euros is appreciated. In Italy, leave 5 to 10 percent for good service. Getting this wrong makes you look like a tourist or a cheapskate, sometimes both. A quick Google search before you arrive saves you the awkwardness.

Health

18. Pack a basic medical kit

Your kit should include ibuprofen or acetaminophen, antihistamines (Benadryl or Claritin), anti-diarrheal (Imodium), antacids, band-aids, antibiotic ointment, and any prescription medications in their original labeled containers. If you take prescription medications, carry a doctor’s note listing each medication and why it is prescribed. Some countries — Japan, the UAE, Singapore — have strict rules on what can be imported, even with a prescription. A friend had his ADHD medication confiscated at Tokyo Narita because he did not have the original prescription with him.

19. Drink bottled water in countries with questionable tap water

In most of Western Europe, North America, Japan, Australia, and New Zealand, tap water is safe. In most of Asia outside Japan and Singapore, Africa, and Latin America, stick to bottled water — including for brushing your teeth. The CDC maintains a country-by-country water safety index at cdc.gov. When in doubt, bottled water is 50 cents to 1 euro per liter. A small price to avoid a ruined week.

20. Use sunscreen even on cloudy days

UV rays penetrate clouds. At altitude (mountain trips, ski resorts) and near the equator, UV intensity is dramatically higher than at sea level in temperate zones. Apply SPF 30+ sunscreen every morning before leaving your hotel, and reapply every two hours if you will be outside. Sunburn not only ages your skin but also dehydrates you — a common cause of fatigue and headaches during travel. I once got badly sunburned on a cloudy day in Cusco, Peru (11,000 feet elevation). The headache lasted two days.

Cultural

21. Learn at least five words in the local language

“Hello,” “please,” “thank you,” “excuse me,” and “do you speak English?” in the local language will open more doors than any guidebook. Locals appreciate the effort, even if your pronunciation is terrible. Download Google Translate’s offline pack for the local language and use the camera translation feature to read menus and signs. I have watched shopkeepers in rural Italy light up when I attempted “buongiorno” instead of starting with English.

22. Dress slightly more conservatively than you think you need to

In religious sites — churches, mosques, temples — covering shoulders and knees is mandatory. In Japan, removing shoes is often required in homes, traditional restaurants, and ryokans. In Middle Eastern countries, women should cover their hair in religious sites. When in doubt, observe what locals wear and dress one notch more conservatively. You will be treated with more respect and avoid being turned away at the door. I once was denied entry to St. Peter’s Basilica because my shorts were an inch above the knee. Lesson learned.

23. Do not photograph people without permission

Locals are not tourist attractions. Asking before photographing — even just a smile and a gesture toward your camera — is the difference between a beautiful interaction and a hostile one. In some countries, including parts of Africa and indigenous communities worldwide, photographing people without consent is deeply offensive or even illegal. When in doubt, ask. The worst that happens is they say no.

When You Get Home

24. Save your receipts for at least 90 days

Travel insurance claims, warranty claims on items purchased abroad, and tax deductions (if you are self-employed and traveled for business) all require receipts. Photograph every receipt before you leave a restaurant or store. The thermal paper most receipts are printed on fades within 6 to 12 months, so a paper receipt alone is not reliable. A photo is permanent. I keep a dedicated album on my phone called “travel receipts” that has saved me twice on warranty claims.

25. Write down what you would do differently while it is fresh

The moment you return home, while memories are sharp, write down three things: what you would pack less of, what you would pack more of, and what you wish you had done but ran out of time for. Save this note in your phone. When you plan your next trip, you will have specific, personalized advice from your past self instead of generic lists. I have a note on my phone from a 2019 trip to Vietnam that I still reference before any Southeast Asia travel.
