Standard Operating Procedure
Never known it to be waived based on Status.
IND just started getting a lot of direct flights recently. Is it possible on the previous flights that one of your segments was in F and the rest were in Y? I think if any segment on the flight is in F you could have checked 3 bags.
As themicah stated, you can check bags up to 70 LBS as an elite no matter what cabin, but I think only F gets 3 bags, and I am not even sure if that exemption is still around. It sounds like it is though. I thought they had reduced both cabins to only 2 bags, but obviously was mistaken.
