CDG is truly Europe's most hideous hub and (not the first time I've said this on FT) the only airport I know of where the Frenchness of the design was placed far and above the safety and comfort of its users!

That said, some aspects of CDG are wonderful! CDG1 is an architectural masterpiece that should be frozen in time and not used anymore!!!!! The whole 60s future "Jetsons" look of CDG1 is a joy to behold and I love the bit where I queue behind a couple of hundred SQ passengers to get on a BD flight to LHR while panicking CDG employees try to sort the queue out!
