Travel Preparation Checklist

A guide to everything you need to prepare before you fly

Your guide to travel preparation

Planning a trip shouldn't feel like running a marathon before you've even left home. Yet somehow, between passport checks and packing lists, simple travel prep can turn into a stress fest that makes the actual journey feel like the easy part.

Here's the thing - good preparation isn't about being perfect. It's about covering the basics so you can focus on the fun stuff, like deciding whether to pack three pairs of shoes or four (spoiler: you'll only wear two).

Why proper preparation matters

Think of travel prep like insurance - boring, but brilliant when you need it. That visa you applied for three months early? Lifesaver. The backup payment card you almost didn't bring? Hero of the trip when your main card gets blocked for "suspicious foreign activity" (aka buying gelato in Rome).

Poor planning doesn't just cost money - it costs peace of mind. Nothing ruins a family holiday quite like discovering your passport expires next month, not next year.

This checklist breaks down everything by timeline, so you're not scrambling to renew your passport the week before departure or googling "do I need vaccinations for Thailand" at 2AM.

Our timeline-based travel checklist

This timeline breaks down what to do when, so you're not scrambling at the last-minute. Start with the earliest items that apply to your trip. Not everything will be relevant for every journey, but having a roadmap prevents those "Oh no, I forgot about..." moments.

The must-do bits you can’t skip

The timeline covers when to do things, but some preparation areas deserve deeper attention. These sections help you understand not just what to prepare, but why it matters and how to do it properly.

Two passports

Travel documents and legal requirements

Passport essentials 🌐

  • Your passport is your golden ticket, but it's not just about having one - it's about having the right one. Most countries require six months validity beyond your travel dates. Canada and Mexico are exceptions, accepting passports valid through your return date, but don't gamble on exceptions.
  • Real ID enforcement starts 7 May 2025 (for US travellers only). For domestic flights, you'll need Real ID-compliant identification or alternatives like valid passports. The process requires proof of identity, Social Security verification and two proofs of residency - allow 2-4 weeks in most states.

Visa applications and timing 💳

  • Tourist visas for popular destinations need 3-6 months advance planning. Business visas require 2-4 months processing. The mistake most people make? Starting applications too late when consulates require in-person interviews with limited availability.
  • Start visa research immediately after booking flights. Embassy websites provide current requirements, but they change frequently. When in doubt, apply earlier rather than risk missing your trip.

Travel insurance that covers what matters 🛡️

  • When you’re travelling internationally, aim for at least £200,000 cover for medical costs and emergency evacuation. Medical evacuations can cost anywhere from £75,000 to £225,000, so this level of cover isn’t just nice to have - it’s essential.

International driving permits 🚗

  • For US drivers, only AAA and AATA can issue an International Driving Permit (IDP). It costs $20, and you’ll need passport photos plus a copy of your valid licence. Make sure you get it before you travel - you can’t pick one up overseas.
  • Your licence alone works in Canada and Mexico, but many rental companies still like to see both documents. Don’t apply more than six months before your trip - IDPs only last one year from the issue date.

Digital document backup strategies 📱

  • Keep your important travel files safe and easy to find. Save encrypted copies in two or three trusted cloud services, store them in offline phone apps, and email them to yourself and someone you trust. Give each file a clear name so you can grab it fast, and test that you can open them before you go.
  • Key documents to back up include your passport photo page, driver’s licence, travel insurance, flight details, hotel bookings, prescription lists and emergency contacts.

Managing your money and budgeting for your trip

Smart ways to stick to your travel budget 💸

  • Get more from your money by using bank ATMs abroad. Airport exchange counters can charge 10-15% more than the market rate, so skip them.
  • Let your bank and card providers know your travel plans, including where you’re going and when, to avoid any surprise freezes.
  • Pack backup cards from different banks and networks. That way, if one is blocked, you’ve still got a way to pay. And if you’re heading overseas, a no-foreign-transaction-fee credit card can save you even more.

Emergency fund tips for travel ⚠️

  • It’s smart to keep a little extra money set aside for the “just in case” moments. Aim for around £75-£150 or $100-$200 in the local currency when you arrive. This covers immediate needs if card payments aren’t possible.
  • Keep this emergency cash separate from your everyday spending money. For extra security, think about using a travel money card. They’re easy to replace if lost and help reduce fraud risk.
  • If you go for a premium travel card, you could also get handy extras like trip delay cover, lost luggage help and emergency medical protection.
Vaccination certificate

Health and medical preparation

Vaccination rules for your trip 💉

  • The vaccines you need depend on where you’re flying and the rules can change fast. Some countries in Africa and South America won’t let you in without proof of yellow fever vaccination. If you’re travelling from a place where polio is still spreading, you’ll need to show you’ve had the jab.
  • It’s best to book a travel health check 4-6 weeks before you go, as some vaccines need more than one dose, spaced out over time.
  • Health agencies are also warning of a rise in measles cases worldwide in 2025, with other viruses on the move in certain regions.

Travelling with prescription medicine 💊

  • Rules around prescription medication can be tricky, and they vary from country to country. What’s fine at home can be banned abroad. For example, Japan doesn’t allow many common over-the-counter medicines like Sudafed, and the UAE has strict rules for pain medication and antidepressants.
  • Before you fly, check the rules for your destination on the country’s embassy website. Always keep your medication in its original labelled container and bring a letter from your doctor explaining why you need it. Using the generic name of the medication can also help, as brand names may be unfamiliar overseas.

Staying healthy before you fly 🩺

  • Give your immune system a head start before take-off. Book a health check 4-6 weeks before you travel to get any needed vaccinations.
  • In the run-up to your trip, aim for 7-9 hours of good sleep each night, eat plenty of whole foods with enough protein, and keep your hydration levels topped up - start sipping more water at least a day before you fly.

Common pre-trip mistakes to avoid

Before you set off, it’s worth dodging a few classic travel slip-ups. Here’s what to watch for so your trip starts smoothly.

  • The passport panic: Assuming your passport is valid when it expires within six months of travel. Most countries won't let you in, and airlines won't let you board. Check this first, not last.
  • The visa procrastination: Waiting too long to apply for visas, especially during peak season when appointments are scarce. Some visa processes take months, not weeks.
  • The medication mistake: Assuming your regular medications are legal everywhere. Research destination laws early - some common medicines are banned in certain countries.
  • The insurance afterthought: Buying travel insurance too late to get pre-existing condition coverage, or skipping it entirely for expensive trips. Medical evacuations can cost over £100,000.
  • The notification neglect: Forgetting to tell your bank you're travelling, then having your cards blocked when you try to use them abroad. Always notify financial institutions of your travel dates and destinations.

FAQs

How far in advance should I start planning my trip?

International travel needs 3-6 months minimum for visa applications and health preparations. Domestic trips can be planned 4-6 weeks ahead for better prices.

Popular destinations during peak season? Start 6+ months early or face limited availability and premium prices.

Do I really need travel insurance for every trip?

For international travel or expensive bookings, yes. Medical evacuations cost £100,000+ and trip cancellations can lose thousands.

For domestic weekend trips, your existing health insurance and credit card protections might be enough.

When in doubt, the peace of mind is worth the 4-10% of trip cost.

What documents do I need to scan and backup?

Passport photo page, driver's licence, travel insurance policies, flight confirmations, accommodation bookings, prescription medication lists and emergency contacts.

Store copies in 2-3 different cloud services and email them to yourself and a trusted contact.

When exactly does the Real ID requirement start?

7 May 2025. After this date, you need Real ID-compliant identification or alternatives like valid passports for domestic flights. Processing takes 2-4 weeks in most states, so don't wait until the last minute.

How much emergency cash should I carry?

£75-£150 ($100-$200) in destination currency for immediate needs like airport transport and first meals.

Keep it separate from your daily spending money and have access to funds through multiple sources - different banks, backup cards, wire transfer capability.

What vaccinations do I actually need?

Depends entirely on your destination and current health status. Yellow fever is mandatory for certain African and South American countries.

Schedule travel health consultations 4-6 weeks before departure because some vaccines need multiple doses with specific timing.

Can I take my regular medications abroad?

Most yes, but some countries prohibit common medications. Japan bans Sudafed, and UAE restricts pain medications and antidepressants.

Research destination laws through embassy websites, carry medications in original containers and get physician letters for controlled substances.

Should I notify my bank about travel plans?

Absolutely. Include specific countries and dates. Carry backup cards from different networks and banks.

Nothing ruins a trip quite like having your cards blocked for "suspicious foreign activity" while you're trying to pay for dinner in New York.

What's the difference between tourist and business visas?

Tourist visas are for leisure travel with shorter processing times (usually 3-6 months). Business visas are for work-related travel, require more documentation, and need 2-4 months processing.

Some countries offer visa-free tourist entry but require business visas for any work activities.

How early should I buy travel insurance?

Within 14-21 days of your first trip payment to waive pre-existing condition exclusions. This timing window is absolute - buy later and you lose crucial medical coverage. For expensive trips, Cancel for Any Reason policies must be purchased within this same timeframe.
