With GOL it would be 0.3x miles, with no minimum, no elite points. TAM earning is on the IB's site by class, but I don't have any experience. I "credited" an ineligible flight to BA just in case, in the beginning of April, and it hasn't shown at all, even as 0. I expext IB to be even worse than BA.
