You can actually go on beauvais airport's website and check what them your shuttle will be leaving depending on your flight. The shuttle cost €15 one way, it's the cheapest option!
The most restarted thing ever. The website told you that you MUST print your ticket, you arrive here and you figure out that you can simply scan your phone. Ryanair another fail.
1 hourand a half waiting by feet, I wonder if there is any better way to organise the shuttle. Never, never seen a thing like that in any civilized airport! Ryanair keep on beeing a bloody company.
