I’ve used FlixBus on several long-distance routes across Europe as part of budget travel, and I’ve noticed the experience can vary a lot depending on the route.
While the prices are generally very affordable and hard to beat, the actual quality of the journey is inconsistent. Some trips are smooth and on time, while others are significantly delayed or less comfortable.
It’s not always clear in advance which routes will be reliable, since the booking system doesn’t provide much indication of expected punctuality or service quality.
For people who have used it frequently, I’m wondering if certain regions or types of routes tend to be more reliable than others, and whether the app’s punctuality estimates are actually accurate in practice.
