I simply cannot tolerate AF Y service. I find the meals, even ex-CDG, to be horrible. I haven't bothered counting how many things count as "courses" as it's irrelevant when you can barely stomach them. Delta's mains, in particular, are far superior, and DL is now rolling out metal silverware in economy.

Granted, it's been a few years since I travelled DL Transatlantic (AMS-DET) but I still remember the inedible, degusting catering. We all have different tastes, but I am surprised you find DL to be "far superior" to AF. I find AF Y meals are by a great margin the best on offer between US and Europe. (edit: TK is actually the best, but noone in their right mind would backtrack to IST to fly to the US)
