Training Wheels,
You are correct. You will notice that at sea level the foil is concave, and at altitude the foil is convex, thus proving your hypothesis.
Another thought.
Suppose this rumor is true, it won't take long for a competitor to realise that providing inflight service will gain them market share, and then inflight catering will come flooding back again.
I used to fly AN just because their catering and service was better, even though their average ticket price was more expensive. I will fly with any airline who treats and feeds me well, even if it costs a little more.
Food for thought
