We are talking about the Liberec game and travelling to Prague ! But yes, you are quite right, Davos is miles from Prague.
As an aside, if you are thinking of travelling to the away Davos game, you can fly via Dublin to Zurich for around £220.
Then travel from Zurich to Davos plus hotels etc. Would imagine it would be quite expensive compared to travelling to watch the away Liberec game in comparison, in total around £500 I'd say.
