They definitely are far more expensive. This is why I maintain loyalty with a frequent flyer program with an airline that has a generally decent business / first class. For shorter flights, I'll sit wherever and gain miles/points, but for anything 3+ hours, I'll use an upgrade (about 15k miles/points) for a better seat and service. This keeps the flights inexpensive, while opening up the option for more leg room when I really need it (I'm 6'6").
