Anecdotally, this is the opposite of what I've experienced. I generally fly first/business class for health reasons, and the quality of the in-flight meals has been steadily declining with most of the airlines I fly. In many cases, the in-flight meal that I can get now barely compares to the $5 snack box I could buy in economy 10 years ago. Maybe it's because I mostly fly domestic and thus generally with US-based airlines, but it's gotten to the point where I sometimes bring food with me through the security line just to have something edible on the plane.
