Okay, serious answer this time. There is no "level of application" in the 25% rule. All discount eco fares on BA will only earn 25%. The system is now set up this way and it is an automated process. The only exception being that the 500 mile minimum is still in place for shorter flights.</font>
This exception as you mention is not so. On an economy tickey which gets 25% mileage you earn 500/4=125 miles for each leg - this is the minimum.
