Disappointed by this airline. Had delays on both legs of trip, which caused us to have to take a taxi from Charles de Gaulles airport to the centre of Paris after midnight seeing as there were no more RER trains running by the time we got there due to the unexplained delays flying out from Warsaw. Was also perturbed by the fact that for the first 30 minutes of the return flight from Warsaw tiny icy flakes popped out from somewhere above me in the plane to fall on my bare skin or trousers. Took me a while to work out what the freezing tingling was as they only fell once every few minutes, but there was clearly a problem of some sort with the airconditioning or defrosting system? Finally, the flight attendants - though friendly - didn't speak up when people got up and moved along aisle during landing on the runway, or when the fasten seatbelts sign was on during turbulence. Their attitude towards safety did make me wonder and I'm not a nervous flyer!
