Anecdotal story/take: The Aegean Airlines (Europe) business seat has much, much better food in a 20-minute flight than the comparable business 5-7-hour flight in the U.S. (And for a lower price, but I'm not sure that is important to the point.)

But the article does take a weird take. Also not sure how collusion is claimed here. I guess CAB counts as a forcing mechanism, but I am not sure one can argue collusion when it is the result of regulation. Was the regulation in bad faith?
