I will be flying from Brussels to ORD and back in May, on a business class ticket. There are direct flights with AA, but I am not very satisfied with US airliners and don't mind a stop anyway.
As I can choose my airliner, I had a good look at the BA, LH, AF, KLM,... websites. I attach most importance to a personalized service, quality of food, the business class seat, and the AVOD system. I have no airmiles program preference. The LH product looks a bit dull/industrial. I am not a fan of AF as the Brussels-Paris link is by train. KLM/NWA have the advantage of going over AMS, which I like a lot as airport, but I have no idea of the quality of their service on 747s (KLM and NWA) or A330 (NWA).
So, BA seem to have the best product (lie-flat, AVOD, lounges,...). But they fly the LHR-ORD with 3 different planes: 777, 747, and 767 planes. Which one would you pick? Are the seats the same quality on all planes? Maybe the 767 offers more personalized service as it is a smaller plane? And its slower airspeed compared to the 747 offers a longer sleep eastbound. I'd go for the 747 if I can be sure that I will be on the upper-deck, but how do I know? On the other hand, the 777 is maybe the younger airframe and thus the most comfortable?
Thank you for sharing your insights!
