I have found a business class award ticket for next summer. SEA-AMS-FCO on NWA with AMS-FCO on KLM. or IAH-CDG-FCO on all AF metal. Both flights are on A330 aircraft. I'm a DL Skymiles PM. I'm ticketed on NWA/KLM though PDX on the way back due to scheduling and award seat availability. Is there a big difference between AF and NWA business cabins? My primary concerns are 1) Seat comfort 2) IFE 3) Food, in that order. I've heard AF is very strict about carry-on allowances, and their staff isn't always the best. I'm pretty sure connecting through CDG is terrible, and I seem to have read AMS is easier. Thoughts? ...
