The verdict

Reviewed by Matthis Duarte · checked 2026-09-05 · how we check

Flix SE was founded in Munich in 2011 by Daniel Krauss, Jochen Engert, and André Schwämmlein, building a network of long-distance buses (and later trains) that runs on a franchise-like model: Flix handles network planning, pricing, booking, and marketing while many buses are operated by partner companies. It has grown into a large European intercity travel platform, now spanning around 45 countries with over 5,600 destinations, and it acquired Greyhound Lines in the US in 2021 to extend its reach into North America. The app is free to use; pricing is per ticket and dynamic, rising with demand and how close to departure you book — a Berlin–Munich one-way fare, for example, was listed from around €30 for a direct bus on a search a week out. Ownership includes a mix of investors: EQT (Swedish) and Kühne Holding AG (the personal investment vehicle of Klaus-Michael Kühne, distinct from the Kühne+Nagel logistics company he also owns) jointly bought a 35% stake in 2024, alongside other holders such as Permira (UK), General Atlantic and TCV (US), and Porsche, with no single investor holding outright control and the founders still leading the company.

What Flix actually does

Flix is the app and website behind FlixBus and FlixTrain, letting travelers search, compare, and book long-distance bus and (on some routes) train tickets across Europe, and car tickets on Greyhound routes in North America. It's one of the widest single booking platforms for intercity travel in Europe, built on a network-operator model rather than owning most of the vehicles itself.

The core product

Flix SE was founded in Munich in 2011 by Daniel Krauss, Jochen Engert, and André Schwämmlein. Rather than running a traditional bus fleet, Flix mostly handles network planning, pricing, booking, and marketing, while many of the buses on its network are operated by contracted partner companies painted in Flix's green livery. That franchise-like structure is how the company scaled to around 45 countries and over 5,600 destinations from a standing start in 2011, and it's also why service quality can vary: you're not always riding with the same operator twice, even on routes that look identical in the app.

What's new or notable

Flix extended into North America by acquiring Greyhound Lines in 2021, meaning a single app now covers long-distance travel booking on two continents. The app itself is free to download and use — you pay per ticket, and pricing is dynamic, rising with demand and how close to departure you book; a Berlin–Munich one-way fare, for example, was listed from around €30 for a direct bus in a search made a week ahead of travel, rising past €60 on the same day for a similar departure time closer to peak demand. Ownership is spread across several investors rather than concentrated in one: EQT (Swedish) and Kühne Holding — the family investment vehicle of logistics entrepreneur Klaus-Michael Kühne, distinct from the Kühne+Nagel freight-forwarding business it also holds a stake in — jointly bought a 35% stake in 2024, alongside existing holders including Permira (UK), General Atlantic and TCV (both US), and Porsche, with the founders still leading the company and no single investor holding outright control.

Who should use Flix

Great fit if…

  • You're booking ahead — dynamic pricing rewards early booking, and Flix is consistently one of the cheapest ways to travel between European cities when booked in advance, often undercutting rail fares.
  • You want one app for a whole multi-country trip — coverage across dozens of European countries, plus Greyhound routes in North America, means one booking flow for most of an intercity itinerary.
  • You're flexible on which bus you end up on — since routes are often run by partner operators, riders who don't mind some variation between trips get access to the widest route network.

Skip it if…

  • You're booking last-minute — prices can rise sharply closer to departure under Flix's dynamic pricing model.
  • Consistent service quality matters more than price — because many routes are run by third-party partner operators rather than Flix directly, punctuality and vehicle condition can vary by route.
  • You have accessibility requirements and are traveling on US Greyhound routes — that part of the business has faced a Department of Justice investigation into disability-accessibility compliance.

Pricing in detail

Flix has no subscription fee; the app is free, and you pay per ticket at a dynamic price that depends on the route, demand, and how far ahead you book.

PlanPriceWhat's included
Single bus/train ticketDynamic, e.g. Berlin–Munich one-way direct buses listed from €30.48 up to €69.98 depending on departure time, in a search made a week ahead of travelOne-way seat on a booked route and departure time
Greyhound ticket (North America)Dynamic, priced per routeOne-way seat on a Greyhound-operated US route, booked through the same app

Where it falls short

  • Regulatory scrutiny — Germany's Federal Court of Justice ruled against Flix in February 2025 over misleading environmental claims ("environmentally friendly," "climate friendly") on its Belgian website, following a complaint from Belgium's economic inspectorate, and its US Greyhound operations have faced a DOJ investigation into disability-accessibility compliance.
  • Dynamic pricing punishes late booking — fares can climb sharply as departure approaches, so the advertised low prices apply mainly to early bookers.
  • Uneven reliability across partner operators — since many buses are run by contracted third parties rather than Flix itself, punctuality and comfort can differ noticeably route to route.

Privacy & data

Flix's booking flow requires standard travel-booking data — name, contact details, and payment information — to issue a ticket, and the app can use location to help with route search or nearby-departure suggestions. We did not find Flix publishing a detailed breakdown of location-tracking behavior or third-party data sharing beyond what's typical for an EU-based travel-booking company operating under GDPR, so we're not stating specifics on retention periods or third-party sharing that we couldn't verify from public sources.

How we checked this

This entry is based on a live fare search on Flix's own German booking site (shop.flixbus.de) for the Berlin–Munich route from an EU browser, checked on 2026-09-05, along with public reporting on the company's founding, its 2021 Greyhound acquisition, its 2024 ownership changes, and the February 2025 German court ruling against its environmental claims plus the US DOJ investigation. We did not book or ride a Flix route ourselves as part of this check; pricing figures reflect what was listed at the time of checking and will vary by date and route.

What you get, what you give up

What you get

  • Covers an unusually wide network for a single app — long-distance buses and trains across dozens of European countries plus North American routes via Greyhound — so one booking flow works across most intercity trips.
  • Consistently one of the cheapest ways to travel between European cities when booked in advance, undercutting rail fares on many routes.

What you give up

  • In February 2025, Germany's Federal Court of Justice (BGH) ruled against Flix over misleading environmental claims and ordered it to stop making them, rather than issuing a fine, and its US Greyhound operations have faced a Department of Justice investigation into disability-accessibility compliance.
  • Ticket prices are dynamic and can rise sharply closer to departure, and because many routes are run by third-party partner operators rather than Flix directly, service quality and punctuality can vary by route.
