Some people say CDG is great, some say that it is hard for connections. It might be hard as the AFs flights are from the part 2 of CDG, the AF hub, and I think Britisch Midland is at CDG1, old terminal.
half of the AF 340 fleet is beeing equiped with PTVs, featuring the "promenade" program, with movies, games, music, geovision...
Hope you will get the chance to have PTVs.
Tempo is quite confortable, as is the 340.
Food is great. (but you might be dissapointed by the snak or breakfast)
Service is in general great.
F/As in general nice...
Hope you will have a great flight !
