More space, nicer seat and quieter cabin. But it's definitely closer to Economy than to Business. Nevertheless, Nowadays I always fly Premium Voyageur if I cannot fly Business. I think it's definitely worth the price ( in particular when you factor in the extra miles). Actually, while I would say for many airlines that Premium Economy is not worth the extra money (compared with Economy), AF's Premium Voyageur is so reasonably priced that for me it always makes sense (unless I am flying Business, of course).
