Every year, summer travel rankings show us where people want to go and how they want to travel. The destinations that rise, the ones that fall, and the choices travellers make along the way often reveal broader changes shaping the travel industry.

Summer has always been one of the busiest travel seasons of the year, and 2026 is no exception. According to Holafly’s 2026 Summer Travel & eSIM Report, 85.4% of respondents either plan to travel or have already travelled this summer, compared with 73% a year ago. International travel is growing even faster, with 46.4% of travellers planning trips abroad, up from 37.6% in 2025.

Major events such as the FIFA World Cup are also helping drive this trend. As travellers increasingly build entire itineraries around major events, host destinations stand to benefit; the United States, for example, ranked as the third most popular summer destination globally this year.

The data also shows that travellers are becoming more adventurous. Rather than visiting just one destination, many are combining countries, cities and experiences into a single journey. As trips become more ambitious, travellers are also relying more heavily on digital tools to help them stay connected and move seamlessly from one destination to another.

How the travel map is being redrawn

Spain remains the world’s most popular summer destination, holding onto the top position for another year. However, the most significant movements in this year’s ranking come from Asia. Japan rose to second place globally, while South Korea recorded the strongest year-on-year increase, jumping from 10th to 4th place. Thailand also entered the global top ten for the first time, reinforcing Asia’s growing appeal among international travellers. In contrast, destinations that performed strongly in previous years lost momentum, with South Africa recording the largest drop in the ranking, falling from 2nd to 9th place.

For years, Asia was often described as a tourism region with enormous potential. That potential is now becoming reality. The region is no longer attracting travellers simply because it feels new or undiscovered; instead, it is increasingly delivering the types of experiences modern travellers actively seek, from rich cultural heritage and world-class food to vibrant cities and unique experiences.

Japan and South Korea offer some of the clearest examples of this shift. Both destinations have benefited from growing international visibility and appeal to travellers looking for a mix of culture, entertainment, gastronomy and modern infrastructure. Their success also reflects a broader trend: travellers are increasingly choosing destinations that offer more than a single attraction, combining multiple experiences within one trip.

While Japan continues to attract visitors drawn by its unique blend of tradition and innovation, South Korea’s rise has been fuelled by the global popularity of Korean culture. Music, television, beauty and cuisine have introduced the country to millions of potential visitors, helping transform cultural influence into tourism demand. Together, both countries illustrate how Asia is becoming one of the most dynamic and influential regions in global travel.

Travellers are building longer trips

The report suggests that travellers are not only changing where they go, but also how they travel. International trips continue to grow in popularity, but perhaps more importantly, travellers are increasingly combining destinations and experiences within the same journey.

The traditional model of visiting one place and staying there for an entire holiday is gradually giving way to more dynamic itineraries; more than half of respondents expect to visit multiple destinations during a single trip, reflecting a growing appetite for exploration and flexibility.

Part of this trend may also be linked to major global events. For the first time in history, the FIFA World Cup will be hosted across three countries — the United States, Mexico and Canada — naturally encouraging travellers to extend their journeys beyond a single destination and explore multiple cities and regions during the same trip.

According to Holafly, 75% of travellers planning to attend the FIFA World Cup expect to visit two or more host cities during their journey. What begins as a sporting event increasingly becomes a broader travel experience, encouraging visitors to make the most of a trip that may already involve long-haul flights and significant travel planning.

But this shift goes beyond major events as travellers are increasingly viewing holidays as a collection of experiences rather than a visit to a single destination. Whether it is combining several cities in Japan, exploring multiple countries in Southeast Asia or extending a business trip with a leisure component, flexibility is becoming a defining characteristic of modern travel.

Connectivity is something as basic as hotel rooms

One consequence of these more ambitious travel patterns is that connectivity is no longer treated as an afterthought. For many travellers, staying connected has become an essential part of the journey itself; navigation, transportation, restaurant bookings, digital payments, translation tools and communication with friends and family all depend on reliable internet access.

While traditional roaming continues to decline slightly, eSIM adoption increased from 19% in 2025 to 27.4% in 2026, making it by far the fastest-growing connectivity option in the survey. At the same time, reliance on local SIM cards and public Wi-Fi continues to fall, suggesting that travellers increasingly prioritise convenience and flexibility over traditional alternatives.

There are some regions where eSIM adoption is growing particularly fast, and Japan is one of them. Nearly half of travellers heading to the country plan to use an eSIM, making it one of the destinations with the highest adoption rates in the report. This highlights an interesting pattern: travellers who are willing to venture further from home and explore new destinations also tend to be early adopters of technologies that make travel easier and more seamless.

How much can one connection failure cost a trip?

One of the most revealing findings in the report has little to do with technology itself and much more to do with human behaviour. Among travellers who have previously experienced stress due to connectivity issues while abroad, eSIM adoption is significantly higher than among those who have never encountered those problems.

This suggests that many travellers only recognise the value of seamless connectivity after experiencing the consequences of not having it. Missed directions, transportation problems, difficulty contacting family members or being unable to access bookings can quickly transform a minor inconvenience into a major source of travel stress. Once travellers experience that frustration, they become much more willing to adopt alternatives that reduce uncertainty.

At the same time, awareness remains one of the biggest barriers to further growth; nearly 30% of non-users say they simply do not know enough about eSIM technology, a figure almost as high as the percentage who continue relying on traditional roaming. This suggests that the challenge is no longer proving the value of eSIM technology, but ensuring travellers know it exists in the first place. Ultimately, the findings reinforce a simple idea: connection is often taken for granted until it fails.

What today’s destinations say about tomorrow’s travellers

The headline from this year’s report could easily be that Japan continues its rise, South Korea is gaining momentum and Thailand has entered the global top ten.

Yet the bigger story is not about destinations, but about travellers themselves. People are travelling further, combining more destinations into a single trip, exploring regions that until recently sat outside the traditional tourism map and relying more heavily on digital tools throughout their journeys. As travel becomes more ambitious, convenience and flexibility are becoming just as important as the destination itself.

The summer travel map of 2026 looks noticeably different from the one that existed just a few years ago, and it will likely continue evolving. Travel demand is increasingly influenced by cultural trends, global events and changing consumer behaviours. Spain remains a perennial favourite thanks to its beaches, climate and cultural appeal, while the rise of Japan and South Korea reflects the growing influence of culture, entertainment and social media in shaping travel decisions. Thailand’s entry into the global top ten follows a similar pattern, combining affordability, strong tourism infrastructure and growing international visibility.

Even destinations that have traditionally performed well can be influenced by global events. The United States, for example, ranked as the world’s third most popular summer destination this year. While it has long been a major tourism market, the fact that it will host the FIFA World Cup alongside Mexico and Canada is likely helping attract additional international interest and encouraging travellers to plan more extensive trips across North America.

If there is one conclusion from this year’s data, it is that travel is becoming more global, more connected and more experience-driven. Understanding where travellers are going remains important, but understanding why they are choosing those destinations may be even more valuable.
