Hi all. I'm traveling to Europe March next year with my girlfriend. I've already booked the departing trip, now I need to book the returning trip. I will be going from CPH to IAH. It's looking like I have two choices for Business Class:

KLM, CPH -> AMS -> IAH, Boeing 747-400 for the main AMS -> IAH leg.
AF, CPH -> CDG -> IAH, Airbus A330-200 for the main CDG -> IAH leg.

Both take around the same amount of time, and cost the same amount of points and nearly the same fees ($524 vs $558, in KLM's favor).

I read that KLM's 747 has lie flat seats in J, and AF does not. But that the food is better on AF. Lastly, I read that AF is in the process of upgrading its fleet to the new reverse herringbone business class seats, but I'm not sure if the A330-200 will be upgraded by the time we are traveling.

Which option would you go with and why? Thanks in advance!
