Ive been wondering this for a long time. Why dont airlines do frequent flyer miles like the hotels do them, instead of miles flown somthing like 4 points for every doller spent. This would help in two ways, it would reward the business traveler on a full fare making him more likely to choose the airline implementing this system, and at the same time would reduce the amount of reward tickets being cashed in by leisure travelers buying the cheapest fares in the long run.
If the airlines awarded 4 points per doller spent a $3,000 business class tickt would net the business traveler 12,000 points which reward them while the $350 net saver type fare from JFK to LAX would get the leisure passenger 1400 miles rather than 6000. I would also go out on a limb and say that overall business passengers are less likely to use all their miles since I know many that just let them accumulate in their accounts and have hundreds of thousands if not millions. What do you guys think?
