If you’re a child of the 1970s, you probably looked to the whimsical optimism of the cartoon show “The Jetsons” for an idea of what the future of travel might look like. We would hop into flying “aero sedans” that folded into briefcases and take holidays on an asteroid.
Obviously, those things haven’t materialized, but some big changes in travel are expected by 2046.
We spoke with industry thinkers and researchers about what travel might look like 20 years in the future. Here is what they told us.
Your AI agent handles everything
The era of search-and-click travel, where consumers spend hours on booking sites comparing flight prices and room options, will be over. Scott Fleming, president of the travel practice at Aon, a global professional-services firm, describes a future where your personal AI agent handles the entire choreography of a trip, from that first search to the final taxi home.
“My agent will know the places I like, it will have insight into my finances, my budget, my risk tolerances, all my preferences from the kind of room I like to my pillow type,” Fleming says. That personal agent will interface with travel suppliers’ AI agents—not a human to be heard or seen—and book trips for people from their front door and back, according to their known likes and dislikes.
If a health risk emerges on a route or a flight is disrupted, AI agents will negotiate a solution in real time. The system will monitor conditions continuously, rerouting, rebooking and adjusting everything so that the traveler never has to make a call or chase a refund. “It will take a lot of that stress out of the process,” Fleming says.
The distributed airport
The modern airport, let’s face it, is a time suck. Ty Osbaugh, global practice leader for aviation at the architectural firm Gensler, believes that’s going to change.
He envisions a solution whereby the airport is deconstructed and scattered across its nearest city. In 20 years, New Yorkers won’t have to go to JFK airport two hours ahead of their flight. Instead, they will walk or take a driverless taxi to a neighborhood terminal, drop their bags and clear security biometrically, simply by walking in. No passport queues, no conveyor belts. Then they‘ll board a small, quiet electric air taxi that transports them and five other passengers from a building rooftop to the airport.
Since passengers have already been processed and completed security screening in town, airports will consist of lean, airside-only gate areas: runways, tarmac and jet bridges that you simply walk onto. If you have an important meeting you can’t reschedule, no worries; Your AI assistant will have reserved one of a handful of phone-booth-size private lounges adjacent to your gate, located where currently there are rows and rows of seats. Your oat cappuccino will be waiting on the conference table. Your wearable device will alert you when it’s time to walk onto the plane.
The system as he sees it will work like a subway network: Rather than all passengers converging on the same congested highway corridor to JFK, they can choose the neighborhood entry point nearest to them.
“The idea is to break the airport into different functions—security processing and boarding—and putting each where people want them, Osbaugh says. “Now all your time wasted at the terminal is completely cleared.”
The key to the successful execution of this distributed airport is penetration into the city itself. It will require terminals to be integrated into the vertical fabric of urban buildings, Osbaugh says. “Imagine if the terminal was part of a skyscraper that had apartments on the lower floors and the convenience that would provide,” he says. The more access points embedded throughout a city—and let’s not forget its suburbs—the more the single biggest source of travel stress disappears: the unpredictable slog from home to gate.
Frictionless security
Getting through security, meanwhile, is in for major changes. Aon’s Fleming sees biometrics replacing document checks across the entire travel experience—not just at airports but woven continuously throughout the journey, including at international borders. Security systems will read your face, as well as your gait, heart rate and physiology while allowing you to keep moving. “These systems will even smell you,” he predicts. “We use dogs now, but I think the level of security will be automated and be a benefit to all.” The queues, the bins, the removing of shoes will have totally disappeared, and you’ll be able to board a plane or ship without any friction.
“For comparison purposes, consider the old toll booth approach at the tollway or turnpike 30 years ago versus the Zip Cash or Toll Tag systems we see today,” Fleming says.
Demand-controlled destinations
Countries like India and China that together account for around a third of the world’s population are moving enormous numbers of people into the middle class. That could lead to even bigger crowds in Rome, Paris and many of the other places that have defined tourism for generations.
Richie Karaburun, a clinical associate professor at New York University’s Jonathan M. Tisch Center of Hospitality, believes “overtourism demand control” will reshape how the world’s most iconic destinations operate. To keep sites from being “loved to death,” cities may set visitor caps, requiring permits during peak seasons and compelling visitors to get timestamped reservations to enter popular sights like many museums do now. “What’s coming next is a shift from managing individual sites to managing entire destinations as controlled systems,” Karaburun says. “So instead of just needing a ticket for the Colosseum, visitors may increasingly need to plan and secure access to Rome itself in advance during high-demand windows.”
The pressure will ultimately redirect travelers toward places that are extraordinary but currently overlooked. “There will be new stars, new destinations added to the tourist’s list,” Karaburun says. “You’re already seeing this shift with Porto and Valencia relative to Lisbon and Barcelona, or Ljubljana and Palermo relative to Venice and Florence,” he says. In Asia, secondary cities like Kanazawa in Japan are gaining traction beyond Tokyo and Kyoto.
Smarter roads
The future of road travel is less about flying cars than about eliminating the tensions and anxieties that make driving so exhausting. Roads, signs, traffic lights and vehicles will increasingly talk to each other, sharing information in real time.
“When a car suddenly slams on the brakes in front of you, it will send out a message to roadway devices and to the cars behind it,” says Philip Plotch, a principal researcher and senior fellow at the Eno Center for Transportation. “You’ll know instantly what happened, giving you more time to react. Or the car might even slow down or stop on its own.”
Even before fully driverless cars arrive, this growing communication between vehicles and infrastructure will make driving safer and less stressful, reducing surprises and smoothing traffic flow. As more advanced automation takes hold, the experience of being in a car will start to feel fundamentally different.
Once you don’t have to keep your eyes on the road, a long drive begins to resemble a train trip, giving passengers time to read, watch something or rest instead of constantly focusing. That shift will change how and how far people are willing to travel, Plotch says.
Faster flight
The physics of travel itself will change by 2046. Supersonic flight—flying from New York to London in under 90 minutes at Mach 3 (three times the speed of sound) for dinner—could become routine for the affluent. Aon’s Fleming points to Boom Supersonic’s planned Overture jet, which is currently running successful supersonic tests at Mach 1.7 and could be in service as soon as the end of this decade. “It’s hard to see us not having supersonic travel in the 2030s at this point,” Fleming says, “but it remains to be seen if it’s at scale or limited to the upper end of the market.” Boom says it expects future versions of its aircraft to become faster and more affordable over time.
Commercial supersonic travel isn’t new, of course. The Concorde cut trans-Atlantic flight times in half beginning in 1976, but the flights were expensive to operate, carried relatively few passengers, consumed large amounts of fuel and faced strict noise limits after sonic booms triggered public backlash, confining most flights to ocean routes. A fatal crash in 2000 and falling demand after 9/11 helped lead to the planes’ discontinuation in 2003.
According to Fleming, the new generation of supersonic startups will be able to leverage advanced technology such as lighter and active-cooling composite materials, more-efficient engines and aerodynamic shapes, sustainable aviation fuel and quieter boom technology, allowing high-speed air travel to finally be commercially viable, especially for premium travelers willing to pay for time savings on long-haul routes.
“Supersonic travel will compress the world in a way we haven’t seen since the Jet Age,” says NYU’s Karaburun. If long-haul flights shrink to a few hours, cities like New York, London and Dubai begin to function less like distant hubs and more like a connected corridor.
Beyond supersonic travel lies hypersonic travel, which involves flying at Mach 5 or above and comes with intense thermal challenges that have yet to be resolved. Fleming notes that some aerospace companies are working to develop such aircraft, though he predicts passenger service won’t be available until “2035–2040 at the earliest.”
Space hotels
This may be a bit farther out, but it’s possible that the true “space hotels”—commercial space stations with hospitality amenities—could emerge as early as the 2030s, says Karaburun.
Like hypersonic travel, Fleming says, these trips at first will be accessible only to the ultrawealthy, but by the 2040s, as launch costs fall, that market could expand modestly. “I expect the first space hotels to be in orbit, much like the [International Space Station] today, with a few nice hotel rooms with a remarkable view, probably combined with a research facility,” he says.
Karaburun sees a similar future. “These will be small, expensive and tightly controlled, more akin to early Antarctic expeditions than traditional tourism,” he says.
