How to Plan a Round-the-World Trip: Cost, Route & Steps

People often treat a round-the-world trip like it belongs to a different category of traveller — someone who wins the lottery, quits their job, and disappears. It doesn't. Strip away the romance and it's a planning problem, and a manageable one. Most of it comes down to two questions: what will the trip actually cost, and how can you plan your route without letting flights consume your budget?

Get those two decisions right, and everything else — where to go, what to pack, and how to stay connected — becomes easier to manage. This guide breaks down the costs, compares flight options, shares a sample itinerary, and walks you through the practical steps to prepare for a long journey around the world.

How Much Does a Round-the-World Trip Cost?

The cost of a round-the-world trip depends on your destinations, travel style, accommodation choices, trip length, and how far in advance you book. The easiest way to estimate it is to separate your budget into two main categories: flights and everyday expenses.

1. Flight Costs

A round-the-world (RTW) airline ticket can cost approximately 3,000–8,000 in economy, although the final fare depends on your itinerary, mileage, travel dates, and ticket conditions. A specialist-built multi-stop itinerary may cost less or more depending on the airlines and routes involved.

For comparison, AirTreks reports that its custom round-the-world flight tickets often fall in the 2,500–3,500 range, including taxes, although individual itineraries vary. Treat these figures as planning estimates rather than guaranteed prices. Compare round-the-world trip costs with AirTreks.

2. Daily Spending at Your Destinations

Your daily expenses can make an even bigger difference to the overall budget. Accommodation, food, local transport, activities, and the time you spend in each country all affect how much you need.

Region	Approximate daily budget per person
Southeast Asia	30–100
South Asia, including India	20–50
Eastern Europe	50–80
Western Europe	80–150
Japan and South Korea	80–120
South America	40–80

These are broad estimates based on typical travel styles, not fixed prices. Staying in hostels, eating local food, and using public transport can lower costs, while private rooms, organised tours, and frequent activities can push them higher. Actual costs vary by country, city, season, and accommodation choices. See AirTreks' regional budget guidance.

What Is a Realistic Budget for a Year Around the World?

There is no single budget that works for every traveller. AirTreks estimates that a year-long trip can cost approximately 25,000–55,000, including flights and everyday travel expenses, although slower travel through lower-cost destinations can bring the total down.

The most effective way to manage your budget is to spend more time in affordable regions and limit your stay in expensive destinations. A few weeks in Western Europe can cost considerably more than the same amount of time in parts of South or Southeast Asia.

Keep your flight budget and daily spending budget separate. A cheap flight into an expensive destination may look like a bargain initially, but accommodation, meals, and activities can quickly make up the difference.

Remember to budget separately for travel insurance, visas, vaccinations, equipment, and emergency expenses.

How to Choose Your Round-the-World Flight Route

Your route influences your flight costs, travel time, and the number of destinations you can comfortably visit. There are four main approaches to consider.

1. Book an Airline-Alliance RTW Ticket

Airline alliances, including Star Alliance and oneworld, offer ways to book multi-destination journeys on a single ticket. These options can be useful if you already have a clear route and want to organise several long-haul flights together.

Rules vary by ticket and provider. For example, Star Alliance's round-the-world fare has requirements relating to the direction of travel, mileage, stopovers, and Atlantic and Pacific crossings. Its official planning tool allows you to build an itinerary and check whether it meets the fare rules.

Explore the Star Alliance Round the World planner before deciding whether an alliance ticket suits your route.

2. Build a Custom Multi-Stop Itinerary

A specialist such as AirTreks can help build a multi-stop itinerary using different airlines. This approach may work better if your preferred destinations do not fit neatly into one alliance's routing rules.

Compare the complete itinerary, including taxes, baggage conditions, change fees, and the cost of reaching each destination. A lower headline fare is not always the best value if it involves inconvenient connections or expensive additional transport.

3. Book Flights as You Go

Booking individual flights through platforms such as Skyscanner gives you flexibility to change your plans as you travel. It can also make sense if you want to stay longer in a destination before deciding where to go next.

The trade-off is that prices and availability can change, and you will need to manage each booking separately. Allow enough time to compare fares and understand the conditions, especially when different airlines are involved.

4. Combine Flights with Overland Travel

You do not need to fly between every destination. In regions with practical bus and train networks, overland travel can reduce flight costs and give you more time to experience the places between major cities.

For example, you could fly into Southeast Asia, travel between several destinations by bus or train, and book your next long-haul flight only when you are ready to leave the region.

This approach can be slower, but it may help you spend less on transport and avoid rushing through your itinerary.

Tools to Help You Plan Your Route

A few online tools can make route planning easier:

• Star Alliance Round the World planner: Explore eligible routes for an alliance ticket.
• FlightConnections: Explore flight routes and see which airlines operate between destinations.
• Skyscanner: Compare individual flight options.
• AirTreks: Explore custom multi-stop flight itineraries.

Compare the total cost and practicality of each option rather than assuming that one booking method will always be cheapest. Booking early can help, but flexibility with dates and destinations can also make a difference.

Building Your Round-the-World Itinerary

Once you understand your budget and flight options, you can start turning your ideas into a practical itinerary.

Step 1: List Your Dream Destinations

Write down the places you most want to visit, then mark them on a map. Look for a route that moves logically between regions rather than repeatedly crossing oceans.

You do not need to visit every destination on your list. Choose the places that matter most and leave room for unexpected discoveries.

Step 2: Decide How Long You Can Travel

Many round-the-world trips last three months to a year, but your schedule should reflect your budget, work commitments, and personal priorities.

A shorter trip may require more careful prioritisation. A longer trip gives you more time to travel slowly, although accommodation and daily expenses still add up.

Step 3: Estimate Your Long-Haul Flights

Identify the major international flights needed to move between continents. Then compare the cost of an RTW ticket with a custom itinerary and individual bookings.

Do not forget regional flights, trains, buses, ferries, and airport transfers. These smaller journeys can become a significant part of your total transport budget.

Step 4: Leave Room for Flexibility

A useful itinerary gives you structure without making every day feel fixed. Plan the broad sequence of destinations and decide which activities need advance reservations, but avoid booking every night too far ahead unless necessary.

Leaving some flexibility makes it easier to extend a stay, change plans, or take advantage of an opportunity that was not on your original list.

A Sample Round-the-World Route

One possible route is:

South America → New Zealand → Southeast Asia → India

This itinerary combines South American landscapes and cities with New Zealand's outdoor experiences, Southeast Asia's food and cultural attractions, and India's diverse destinations.

Another option is an eastbound journey:

Europe → South Asia or Southeast Asia → Australia or New Zealand → the Americas

These are starting points, not fixed itineraries. Before choosing a direction, compare seasonal weather, visa requirements, flight availability, and the cost of travelling in each region.

Follow the Seasons Where Practical

If you want to pack light, plan your route around the weather. Travelling through warmer destinations during their suitable seasons may reduce the need to carry bulky winter clothing.

However, chasing summer is not always the cheapest or most practical option. Consider local rainy seasons, extreme temperatures, major events, and peak travel periods before finalising your route.

Before You Go: Essential Travel Logistics

The practical work before departure can make a long trip much easier. Start preparing well in advance and work backwards from your planned departure date.

Set a Savings Target

Calculate your expected flight costs, daily spending, visas, insurance, vaccinations, equipment, and a contingency fund. Divide the amount you need by the number of months remaining before departure to create a realistic savings target.

Review your budget as you make bookings and confirm prices. Your initial estimate should be a starting point, not a limit you cannot adjust.

Check Visa Requirements

Check entry and transit requirements for every country on your route using official government sources. Some visas require advance applications, supporting documents, or processing time.

Also check passport validity, permitted length of stay, onward-travel requirements, and any entry authorisations that apply to your nationality.

Plan Your Health and Medication Needs

Arrange a consultation with a travel-health professional well before departure. Recommended vaccinations and precautions depend on your destinations, planned activities, and medical history.

Carry necessary medication in its original packaging where possible, along with relevant prescriptions. Check whether any medication is restricted in the countries you plan to visit.

Choose Suitable Travel Insurance

Look for insurance designed for the duration and type of travel you are planning. Check coverage limits, medical emergencies, evacuation, baggage, trip interruptions, and any activities you intend to do.

Read exclusions carefully and confirm whether you need additional coverage for particular destinations or adventure activities.

Budget for Equipment and Preparation

A backpack, suitable footwear, travel adapters, essential clothing, and other equipment can add up. Include these costs in your plan instead of treating them as last-minute purchases.

Pack for Multiple Climates

Choose versatile clothing that can be layered, dries reasonably quickly, and works across several settings. A reusable water bottle, basic first-aid supplies, travel documents, and suitable footwear are useful starting points.

Pack only what you expect to use regularly. Carrying less makes airport transfers, public transport, and moving between accommodation much easier.

Staying Connected Across the World

Your phone becomes an important travel tool on a round-the-world trip. You may use it to navigate unfamiliar cities, book accommodation, check transport schedules, translate information, manage reservations, and contact family.

Buying a new local SIM card in every country can be time-consuming, while international roaming charges may become expensive. A travel eSIM offers another option for accessing mobile data in supported destinations.

Use a Global eSIM for Multi-Country Travel

An Airhub Global eSIM can help you stay connected across multiple supported countries without needing to replace your physical SIM at every border. Airhub offers global plans with different data allowances and validity periods, and eligible plans support top-ups without reinstalling the eSIM.

Coverage, data allowances, validity, network availability, and calling or SMS features depend on the specific plan. Check that the countries on your itinerary are covered before purchasing, and confirm that your phone supports eSIM and is carrier-unlocked.

Explore Airhub Global eSIM plans to compare available options for your trip.

Install Your eSIM Before Departure

Install your eSIM while you still have access to a reliable Wi-Fi connection. Follow the plan's instructions and check how activation and validity work before you leave.

You can use our eSIM installation guide for step-by-step instructions.

Before travelling, download essential maps, booking confirmations, tickets, and important documents for offline access. Keep key contact details available even if you temporarily lose mobile data.

An eSIM can make connectivity easier, but it does not guarantee coverage everywhere. Remote areas, local network conditions, and the specific plan you choose can affect service.
