The App That Booked My Entire Trip and Got Everything Wrong

The App That Booked My Entire Trip and Got Everything Wrong

AI-powered travel planning tools promise to end the hours spent building itineraries. I tested three of them for a two-week trip to Japan. The results ranged from genuinely useful to dangerously bad.

I've been planning trips manually since 2016. Spreadsheets for flights. Google Maps with pinned restaurants. A notes app full of booking confirmations an museum hours and train schedules. It takes me approximately four to six hours to plan a two-week international trip. I enjoy it. My husband does not. He's been waiting for technology to rescue him from my color-coded spreadsheet system.

In June 2026, I let three AI travel apps take a crack at replacing me.

the first test was almost impressive

I used Wanderplan, a well-funded startup that launched its AI itinerary engine in late 2025. Input: two weeks in Japan, Tokyo to Kyoto to Osaka, moderate budget, interest in food and history, dates in July. Output: a day-by-day itinerary with hotel suggestions, restaurant picks, museum entries, and transit routes between cities.

The first three days in Tokyo were solid. Wanderplan suggested the Yanaka district for a morning walk, a ramen shop in Sugamo that I'd rarely heard of, and the Shitamachi Museum in Ueno, all of which were reasonable an logistically coherent. The app even calculated transit times between stops and warned that the Tsukiji Outer Market is less crowded after 10 a.m.

Then it fell apart. Day four had me visiting both the Ghibli Museum in Mitaka and teamLab Borderless in Azabudai Hills on the same afternoon. These are both timed-entry attractions on opposite sides of Tokyo. The Ghibli Museum requires advance booking months in advance and doesnt allow photography. teamLab Borderless takes two to three hours minimum. The app had em scheduled 90 minutes apart with a 45-minute transit window. Impossible.

I flagged the conflict in the app's feedback system. It regenerated that day's plan an moved teamLab to the following mornin. The fix took about 30 seconds. But I checked the fresh plan and now it had me doing teamLab at 9 a.m. when the venue doesn't open until 10. The AI had no understanding of operating hours. It was pattern-matching from guidebook data without verifying constraints.

the second app hallucinated a restaurant

I tried Roamr AI next, feeding it the same Japan trip parameters. Roamr generated a restaurant recommendation in Kyoto: a modest kaiseki place near Kiyomizu-dera that it described as "a hidden gem with only eight seats, known for its seasonal Kyoto vegetables an traditional multi-course presentation." It included a photo that looked like it had been pulled from a stock library.

I searched for the restaurant. Google Maps displayed nothin at the address. Tabelog, Japan's restaurant review platform, had no listing. I cross-referenced the phone number the app provided. It belonged to a dry cleaner in Osaka.

The restaurant didn't exist. Roamr's AI had fabricated it entirely, including the atmospheric description, the photo, an the phone number. When I reported this, the developer acknowledged it as a "known issue with our content generation pipeline" and said they were "working on verification layers." That's not reassuring when the tool is sposed to tell you where to eat dinner in a foreign country.

boring recommendations are almost worse

The rest of Roamr's itinerary was less catastrophically wrong, just boring. It suggested chain hotels that any Google search would surface, tourist attractions straight from the top 10 list on TripAdvisor, and restaurants with average ratings of 3.8 or below. The AI wasn't adding value. It was reorganizing obvious information into a daily format and charging $12.99 a month for the privilege.

the third one actually saved me money

TripAI, a tool built into a major travel rewards credit card's app, took a different approach. Rather of generating an itinerary from scratch, it improved an existing one. I fed it my spreadsheet and it analyzed the flight bookings, hotel reservations, and restaurant picks for cost savings an timing conflicts.

It found three things I'd missed. My flight from Tokyo to Osaka on JAL was 50 euros more expensive than a similar ANA flight departing 40 minutes later. My hotel in Kyoto was offering a 15 percent discount for stays of four nights or more, and id only booked three. The restaurant I'd booked in Shinjuku had a lunch set menu for 2,200 yen that wasn't listed on the English website but appeared on the Japanese version.

Total savings: about 180 euros on a two-week trip. That's real money. TripAI didn't plan my trip. It made my planning better. The distinction matters.

what ai travel tech actually gets right

The best application I found wasn't itinerary generation. It was real-time rebooking. During the trip, a train strike in France disrupted my Eurostar connection from Paris to London. Google Travel's AI assistant detected the disruption from railway operator alerts, rebooked me on the next available Eurostar departure, sent the fresh ticket to my phone, and adjusted my hotel check-in notification to reflect the later arrival. The entire process took about 90 seconds. Fore AI, I would have laid out an hour on hold with Eurostar's customer service.

Flight disruption handling has improved similarly. My husband's United flight from San Francisco to Tokyo was delayed by mechanical issues, an the airline's AI rebooking tool automatically placed him on the next day's ANA codeshare while we were still standing at the gate. No human interaction required. The old system would have had us queue at the customer service desk for two hours.

translation tech is the quiet winner

Language translation is another area where AI has made genuine travel improvements. Google's real-time translation on Pixel phones now handles Japanese signage, menu text, and spoken conversation with enough accuracy that I navigated two weeks in Japan without a single moment of language panic. The app even translated handwritten kanji on a chalkboard menu outside a noodle shop in Nara. My 2019 self, armed with a phrasebook and alot of pointing, would have been amazed.

what the travel industry isn't telling you

The tech improvements are real, but they're unevenly distributed. A solo traveler with a flagship smartphone and a premium credit card gets the full benefit of AI assistance. A family of four with budget phones and nah loyalty status gets the basic experience. The technology is widening the gap between premium and economy travelers, not narrowing it.

A travel agency colleague told me her agency's AI booking tool, which costs $200 a month per agent license, has reduced her booking time by about 30 percent for standard itineraries. But for complex multi-country trips with special requirements, she still builds em manually cuz the AI can't handle the edge cases. "It's great for Fresh York to Paris round trips," she said. "It's useless for anything with more than three stops and a visa requirement."

I'll keep using AI tools for the parts of travel planning where they honestly help. Real-time disruption management. Price optimization. Language translation. But the creative part of building an itinerary, choosing between a tiny kaiseki restaurant and a lively izakaya, deciding whether to spend the morning in a museum or wandering a neighborhood with no plan, that's not a problem AI solves. That's travel.
