Just because AF is the dominant party of the new program doesn't mean that every FD policy will necessarily be scrapped.

The F+ people presumably can analyze the pros and cons of FD and F+ and attempt to incorporate the best of both programs, where such policies are financially viable and sustainable.

Remember, FD has a strong track record with the structure of their program (though not necessarily the execution of it!!). I think FD can make a strong case for retaining policies like

Webawards
benefit to airline; fill seats during offpeak periods; reduce mileage liability by allowing more award reemption opportunities
benefit to members: discounted award travel

One Way awards
benefit to airline: reduce mileage liability by allowing more award redemption opportunities
benefit to members: terrific flexibility of award usage

100% COS bonuses
benefit to airline: COMPELLING incentive to fly paid Business Class, whereas 25-50% COS bonus is not enough incentive; better ties mileage earning to money spent
benefit to member: ability to earn top-tier status more quickly, efficiently


I think FD has far less leverage in defending upgrades on ANY fare pr mileage earning on ANY fare.
