Vaccination & Health Checklist
- Routine vaccinations — Ensure your tetanus, MMR, and flu shots are current
- Destination-specific vaccines — Yellow Fever (required for parts of Africa and South America), Hepatitis A & B, Typhoid, Japanese Encephalitis, Rabies (for adventure travel)
- COVID-19 considerations — While most countries have dropped requirements, some may reinstate them during outbreaks. Check your destination's current entry rules
- Malaria prophylaxis — Consult your doctor if traveling to tropical regions in Africa, Southeast Asia, or Central America
- Prescription medications — Carry enough for your trip plus extras. Keep them in original packaging with a doctor's letter describing the medication and dosage
- Travel health kit — Pain relievers, anti-diarrheal, antihistamines, band-aids, antiseptic, rehydration salts, insect repellent, sunscreen
💰 Financial Preparation
Money problems abroad are among the most stressful travel issues. A little preparation goes a long way.
Heading to Europe? Our Italy packing guide has specific tips.
- Notify your bank — Tell them your travel dates and destinations so they don't freeze your card for "suspicious" foreign transactions
- Get a travel-friendly card — Cards like Wise (TransferWise), Revolut, or a no-foreign-transaction-fee credit card save you 2-3% on every purchase
- Carry some local currency — Have the equivalent of $50-100 in local currency for taxis, tips, and emergencies upon arrival. Airport exchanges have terrible rates, so order currency from your bank before departure or withdraw from ATMs at your destination
- Know the exchange rate — Familiarize yourself with rough conversions so you don't overpay. PackSmart's currency converter can help!
- Emergency cash backup — Keep a small amount of USD or EUR hidden separately from your main wallet. These are widely accepted in emergencies worldwide
- Photocopy your cards — Note down your bank's international helpline number in case your card is lost or stolen
📱 Digital Preparation
Your phone is your most powerful travel tool. Set it up properly before you leave.

- Download offline maps — Google Maps lets you download areas for offline use. Do this on Wi-Fi before departure
- Get an eSIM or local SIM plan — Services like Airalo or Holafly offer affordable eSIMs for most countries. Much cheaper than international roaming
- Download a translation app — Google Translate works offline if you download the language pack in advance
- Save emergency numbers — Police, ambulance, your country's embassy or consulate, and your travel insurance hotline
- Set up a VPN — Protects your data on public Wi-Fi networks at airports, hotels, and cafés
- Enable two-factor authentication — Secure your banking apps, email, and social media before traveling
- Download your airline's app — Mobile boarding passes, real-time flight updates, and easy rebooking if things go wrong
⏰ The Countdown Timeline
Here's when to do what, so nothing falls through the cracks:
Make sure you have travel insurance sorted.
3 Months Before
Check passport expiry (renew if less than 6 months validity remaining). Apply for visas if required. Schedule vaccinations. Book travel insurance.
1 Month Before
Notify your bank. Order foreign currency. Get International Driving Permit if needed. Buy an eSIM. Start a packing list.
1 Week Before
Print/save all documents. Download offline maps. Share itinerary with family. Check weather forecast. Confirm hotel bookings. Download airline app.
1 Day Before
Online check-in. Final pack and checklist review. Charge all devices. Set alarm. Check flight status. Place passport and documents in carry-on.
Travel Day
Arrive at airport 3 hours early for international flights. Carry documents in an easily accessible pocket. Keep medication in carry-on. Have entertainment downloaded for the flight.
🏠 Home Preparation
Don't forget about what you're leaving behind:
Compare flights for your international trip.
- Arrange pet/plant care — Confirm with your sitter or ask a trusted neighbor
- Hold or redirect mail — An overflowing mailbox signals an empty house
- Set timers on lights — Creates the appearance someone is home
- Unplug unnecessary electronics — Saves energy and protects against power surges
- Lock up valuables — Store important documents and valuables in a safe or with a trusted person
- Leave a key with someone you trust — In case of emergency at home while you're away
- Check stove, iron, and taps — You'll thank yourself for not worrying about this on the plane
🎒 What to Carry On Your Person
Keep these items in your carry-on bag or on your body at all times during transit:
- Passport and boarding pass
- Phone, charger, and power bank
- Wallet with cards and some cash
- Travel insurance card/printout
- Prescription medications
- A change of clothes (in case checked luggage is delayed)
- Pen (for immigration forms on the plane)
- Snacks and a refillable water bottle (fill after security)
🌍 Country-Specific Considerations
Different regions have unique requirements that catch travelers off guard:
Europe (Schengen Area)
Starting in 2026, non-EU travelers from visa-exempt countries (including the US, UK, Canada, Australia) need an ETIAS authorization — an online form costing €7, valid for 3 years. Apply at least 72 hours before travel. The 90/180-day rule applies: you can stay a maximum of 90 days within any 180-day period across all Schengen countries combined.
United States
Visitors from Visa Waiver Program countries need an ESTA ($21, valid 2 years). Apply at least 72 hours before departure. Travelers from other countries need a B-1/B-2 visa — apply months in advance as interview wait times can be long.
Southeast Asia
Many countries offer visa-on-arrival or visa-free entry for 30 days. Thailand, Vietnam, Malaysia, Singapore, and Indonesia all have different rules. Always check the latest requirements as these change frequently.
Middle East
UAE offers visa-free entry for many nationalities. Saudi Arabia now offers e-visas for tourists. Be aware of strict customs regulations — some common medications and items may be prohibited.
