Flew AF LHR-CDG-LHR last year and impressive as it is, it's underwhelming. The wing is ENORMOUS so I couldn't see out of the window which due to the double deck is quite far away from the seat so I couldn't rest me head against it. The take off is really quiet and not at all impressive alas.
Nice piece of kit for Joe Public though but for an enthusiast, I'm glad I did it but it's not something I'd be in a hurry to repeat.
Also, it is most FUGLY which doesn't help.
