Has anyone used the Flick Bus? Looking to take it from Prague to Salzburg bc I found out there's construction from Linz to the Austrian border and we'd have to take 2 trains and a bus.
Assume you mean FlixBus.
Yes, I have. Here's a recent thread:

Used Flix bus twice this year between Lisbon and the Algarve and all was good-clean bus and on time.
Great, thank you.
