I do use Eurofleet sometimes. That is if Eurofleet is the one that services LHR to CDG. It's hard to judge though, because more often than one would like, you arrive at LHR to find on your LHR-CDG sector you have been downgraded to economy because they've changed the flight to eliminate Club Europe.
Also, the only thing you can reasonably enjoy on a 45 minute flight....is your better seat! Not time for much service. Though I always appreciate the cabin crew at the front who immediately confront with a smile the back of the plane denizens who try to stash their capacious reticules in the first CE overhead bin they encounter upon embarking and heading to the back!
That's service!
