Additionally, frequent flyer loyalty is dead-meaningless to the business traveler. I'm a million miler on one airline and it gives them only the least edge. My expenses are scrutinized, so it is a balance of fare price and schedules, with my preferred airlines coming last.
Loyalty is like an available frequent flyer seat-nonexistent.
Perhaps this wouldn't be so if the airlines had made airline point a profit center. They probably made a lot of money, but at what cost?
