Searches for solo travel hit a 15-year high in 2026. The market is now worth $549 billion and growing at 14.6% annually. This is not a niche trend anymore — it is how a significant and growing share of the world has decided to travel. Here is what the data actually says, and what it means for how you plan your next trip alone.

The conventional story about solo travel is that it is mostly young people with gap years and hostels. The 2026 data breaks that story in several places at once. Women make up 84% of all solo travelers globally. Thirty-nine percent of solo travelers are now 40 or older. The market grew faster than the broader travel industry for the fourth consecutive year. And in a finding that surprised even the researchers who tracked it: TikTok solo travel content increased tenfold in three years, with the majority of that content coming from women over 35 documenting ordinary city trips, not extreme adventures.

The trend has infrastructure now. Dedicated solo travel insurance products, solo-supplement-free hotel rooms, apps built specifically for one person planning a city without someone else to negotiate with. The hesitation that used to come with booking alone — is this safe, is it weird, who will I talk to — is dissolving at scale. According to a March 2026 survey by the Solo Female Travel Club, 63% of first-time solo travelers plan to do it again. Once you try it, the data says, you are converted.

The numbers behind the shift

The market size figures are striking, but the behavioral data is more interesting. Solo travel is not growing because more people are lonely or single — it is growing because people have separated the idea of traveling from the idea of waiting for someone else to be available, interested, and able to afford the same thing at the same time. That coordination problem is the one solo travel solves.

The demographic shift is as significant as the market size. The fastest-growing segment of solo travelers is not Gen Z — it is women over 40, who according to the 2026 Solo Female Travel Trends Survey worry less about safety than younger cohorts, have done it before (37% have taken more than ten solo trips), and are choosing destinations based on cultural depth rather than how photogenic they are on Instagram. This group travels for food, history, and walking — which maps directly onto what a good city guide app can actually offer.

What solo travelers actually struggle with

The motivations for going alone are clear. The friction points are equally well-documented. A 2026 survey found that 49% of solo travelers worry about loneliness. The research behind that number, though, is more nuanced: the loneliness concern peaks before the trip and drops significantly once the traveler is actually somewhere. The thing that sustains the worry pre-departure is not social isolation — it is the planning burden. When you are traveling with someone else, the planning gets distributed. Solo, every decision sits with one person.

Which restaurants, which neighbourhood, which museum first, how to get from the airport to the hotel without paying for a taxi that costs more than the flight. The solo traveler does not have a partner to say “you figure out the first day, I’ll figure out the second.” All of it lands on the same person who also has to pack, show up on time, and remember the tickets.

The top destinations, and why they work for solo travel

The 2026 safety and preference data clusters around a consistent set of cities and regions. Iceland, Portugal, Japan, Ireland, and Denmark repeatedly top safety rankings for solo travelers. Spain scores 7.45 out of 10 on solo female safety indices — the highest of any non-Nordic country. The cities that appear most frequently in “best for solo” lists share the same characteristics: walkable, navigable on public transport, rich in free or low-cost cultural sites, and with a street food or cafe culture that makes eating alone unremarkable rather than conspicuous.

Where Wingman fits in the solo travel stack

The friction points solo travelers report — planning complexity, safety in new cities, budget management, language barriers, navigation — are a direct list of what a city guide app needs to solve. Most apps solve one or two of them. Wingman is built around all of them in a single itinerary.

When you generate a Wingman itinerary for a solo trip, you get a day-by-day walking plan with mapped routes and timed distances between stops. The city guide bundled into every itinerary includes a safety section with local dos and don’ts, emergency numbers, and neighbourhood-by-neighbourhood notes — the kind of information that is scattered across five blog posts and a Reddit thread otherwise. The budget breakdown covers hotel, food, transport, and activities across three spending levels, so you know before you arrive whether your daily budget is realistic. The language tips include pronunciation audio for key phrases. The audio tours run through your headphones at each major stop — which, for a solo traveler, is the closest thing to having a knowledgeable companion without needing one.

The Wingram element is worth dwelling on. One of the consistent findings in solo travel research is that the loneliness concern dissolves fastest when travelers can connect with a community — not necessarily in person, but in the sense of knowing that other people have walked the same streets and found them worth it. The ability to share a completed Wingman itinerary to the community feed, and to discover other travelers’ routes before you depart, addresses exactly this.

The gender data, and why it matters for how apps are built

Eighty-four percent of solo travelers being women is not a statistic that most travel app companies have responded to in their design. Most city guide apps are built around the assumption of a pair or group — itineraries that assume a partner to navigate with, safety information that is either absent or buried, social features that require mutual connections rather than a public community. The solo female traveler who arrives somewhere alone at 11pm needs to know which neighbourhoods are fine to walk through and which are not. She needs language tips that go beyond “where is the train station.” She needs a budget breakdown that tells her whether the neighborhood she is staying in has restaurants she can eat at alone without attracting attention.

What the $1 trillion projection actually means

The market is projected to reach $1.07 trillion by 2030 at a 14.3% compound annual growth rate. To put that in context: the broader travel industry grows at roughly 5–7% annually. Solo travel is growing at twice that rate. The gap reflects a structural shift — not a cyclical one — in how people decide to see the world.

The $1 trillion figure also reflects a change in the profile of the solo traveler. The backpacker spending $20 a day in Southeast Asia is still there, but the growing segment is the 42-year-old booking a week in Lisbon on a moderate budget, eating well, visiting museums, taking one good walking tour, and coming home more certain than she was before that she can do it again somewhere else next year. That traveler is not a niche. She is the mainstream of solo travel in 2026, and she is looking for tools that treat her itinerary as something to build properly, not something to improvise.

The city guide app that is built for this traveler — not as an afterthought, but as the primary user — has a significant market to address. Wingman covers 155 cities, runs audio tours for 650+ routes, and bundles safety, food, transport, language, and budget information into a single itinerary. It takes 45 seconds to generate one for any city. It costs nothing. The solo traveler who lands in Lisbon alone at 7pm and opens the app has, within a minute, a day-by-day plan, a safety guide, a list of places to eat alone without it being awkward, and audio company at every major stop.

That is not a small thing. It is the difference between the trip that happens and the trip that stays on the saved list.
