I have a special fare ticket DFW-GRU-DFW.
We have now decided to go to GIG instead.
The fare difference is very high.

Can I book AA951/950 GRU-GIG-GRU on an award ticket? This would have to be on a different PNR.

I know it is suppose to be for on-line connecting traffic only. We would be this as we would be making an immediate connection DFW-GRU-GIG.

I would prefer this over GOL if possible.
