if you book closer to the time youre more likely to get a cheaper ticket on www.easyjet.com http://www.flights4less.co.uk/

i just did an advanced search on www.cheapestflights.co.uk

and it said the cheapest thursday-monday bristol-prague flight was... da da da da..

stupid stupid stupid stupid confusing websites at 5am.

goodnight.

my advice is wait till later- get cheaper flights.
