Avionero is an AI flight search engine from Malmö that takes a country, a theme, or an open date range instead of a fixed city and day, and returns flights, hotels, and experiences together.
About Avionero
What Is Avionero
Avionero is a flight search site operated by Avionero AB in Malmö, Sweden. Lars Kristensson and Anton Tyulenev founded the company in 2015, and the first open beta went live in Sweden in January 2018. The search engine is built in house. It doesn't run on a large language model; the company describes it as a custom AI system meant to stay energy efficient while sorting through inventory from airlines and major travel sites.
The product targets a gap most search engines ignore. Traditional flight search assumes you already know where you're going and when. Avionero lets you start with a country, a continent, or the word anywhere, add a theme such as beach or warm weather, and give a date range rather than one departure and one return. The engine ranks the combinations by relevance, price, and value, then attaches hotel options and experiences to each flight.
Two limits matter. Avionero doesn't sell tickets, so every booking finishes on an airline or travel agency site, and multi-city itineraries aren't supported. The bigger caveat is the company's status. After canceling a planned listing on Spotlight Stock Market in late September 2026, the board decided on 9 October 2026 to file for bankruptcy. The site was still reachable in late October 2026, but how long it keeps running is an open question.
Getting Started
- Open avionero.com in a browser, or install the iOS or Android app. Searching doesn't require an account.
- Set the basics: departure airport, destination (city, country, continent, or Anywhere), number of travelers, and cabin class.
- Open the date calendar and choose exact days, a range, or a weekend pattern if your plans are loose.
- Read the ranked results. Each option lists price, total travel time, a CO2 estimate, and hotel suggestions for the same dates.
- Select a flight and continue to the airline or travel agent to complete the booking. Avionero takes a referral fee for the handoff.

Key features
Flexible Destination Search
Instead of a city or airport code, you can enter a country, a continent, or Anywhere. This is the core of the flexible flight search idea: the engine explores destinations you didn't name and returns the ones that match your budget and dates. Themes such as beach or warm destinations narrow the pool further.
Date Range and Weekend Calendars
The calendar accepts a spread of dates, a fixed number of nights, or a weekend pattern. The recommendation engine then tests the combinations and ranks them, which saves the manual work of checking several date pairs one by one. For anyone with slack in their schedule, this is where most of the savings show up.
Flights, Hotels, and Experiences in One Search
Each flight result comes with hotel options for the same dates and location, plus experience suggestions. You still choose the hotel yourself, so it works more like a bundled view than a package tour. The point is to skip re-entering the destination and dates on a second site.
AI Recommendation Engine
Avionero ranks options by relevance, price, and value rather than price alone. A cheap itinerary with a 20-hour layover won't automatically sit at the top. The ranking is the part the company built in house, and it's the reason the site can handle vague inputs like a continent plus a month.
Saved Trip Tabs
You can keep several searches open in tabs on the left of the screen and compare them in parallel. The tabs, filters, and preferences are remembered on the same device, so a planning session that spans a few days doesn't start from zero. It's a small feature that matters when you're tracking three possible trips at once.
CO2 Estimates per Itinerary
Flight details include a CO2 equivalent calculated by the partner Trikorona, so you can weigh emissions against price. The figures sit next to the fare rather than behind a separate report. Avionero also links to a carbon offset option for travelers who want to pay for the footprint.
Pros and cons
Pros
- Handles vague trip plans: a country, a theme, or an open calendar works as a starting point, which most flight search engines can't do.
- Wide price coverage: results come from airlines directly and from large travel sites, so the cheap flights list draws on several sellers.
- Free to use with no markup: Avionero takes a referral fee from partners and says it doesn't add commission to the fares you see.
- Hotel and experience context: each itinerary arrives with places to stay and things to do for the same dates.
- Emissions data on the results page: the CO2 flight emissions estimate makes a greener choice visible without extra research.
Cons
- No multi-city trips: the company says combining several routes isn't supported yet, so round-trip and one-way searches are the limit.
- Booking happens elsewhere: Avionero doesn't sell tickets, and support for changes or refunds sits with the airline or agent you're sent to.
- No public API: there's no developer access, so the search can't be wired into another app or workflow.
- Uncertain future: the October 2026 bankruptcy filing puts the service's continuity in doubt, and there's no migration path for saved trips.
Frequently asked questions
Yes. Searching and comparing flights costs nothing, and you don't need an account. Avionero earns a referral fee when you click through to a partner and book there.
