The product is not quite as good and the service is... well its Air France, a by-word for shabby service.
The seats are Ok, but nothing special. The food is admired by some, but for your more experienced traveller it is nothing special, and the wine selection - which used to be excellent - is now no better than average.
Look back over these threads and you will get the idea...
Premium is not something AF does well, I'm affraid. I can't remember the last time they did wel in any reputable survey etc.
On the plus side, they have improved there Frequent Flyer Program this year!
They also have L'Espace Le Club and Alize Class on some routes to the Carribean and Indian Ocean.
