However CDG has put a lot of work on other connections and it's not as bad as it once was, particularly if staying within the same part of T2C-T2A, for example. The other factor is that France tends to have the same fares / sales cycle as other parts of Europe so it's often the case that ex BRU, LUX, AMS, CPH (etc) are simply cheaper and all are easier than CDG. Even within France, LYS, NCE or perhaps MRS would be better than CDG and typically similar fares.
