Which previous program?

For as long as M+B has had the feature of reducing the Tier Miles requirement upon taking a certain number of flights on A3 and/or OA, they have never differentiated between flights in Economy and Business; a flight is counted as 1, regardless of the type of flight (domestic/international), class of service (Economy/Business), sector length or price paid (so long as it is not a M+B redemption flight)
