FlixBus runs Europe's largest long-distance coach network, reaching thousands of towns and cities that trains do not always serve. FlixBus is built around low fares, so it is a popular choice for students and budget travellers who want to get between countries without paying for flights.
The coaches come with comfortable seating and free Wi-Fi, and because a full bus carries a lot of people at once, it is one of the lower-carbon ways to travel. You book online or through the app and turn up at the stop, which keeps the whole thing simple.
