I just realized that our Delta flights from DC to Naples, via Paris, are on Air France.(thought we'd be on Delta). We are flying Premium Economy, supposedly on the newer A350-900-I know the aircraft can change between now and trip day. I've read mixed reviews on their seats. I have tickets through Tauck so of course I can make a change anytime-other option is Lufthansa. Any experience on seat comfort in PE on Air France vs. Lufthansa?
