The link below indicates that "O" class is not eligible for mileage accrual in AAdvantage making it unlikely that it would be in other programs.
Yes - I know that AAdvantage does not allow it. But I thought that another mileage programm allow it...
Certain airline tickets are not eligible for earning mileage credit. These include, without limitation, the following: all tickets issued as AAdvantage awards or other free ticket promotions including free or reduced rate tickets; companion tickets; charter flight tickets; travel agency/ industry reduced rate tickets; infant and unpublished fares. (American Airlines tickets booked in O class or tickets booked in Q class with travel originating in Europe); and tickets issued subject to special provisions.
