My wife and I are both AS MVP.

I have read of many experiences here on FT where people purchased a ticket for BA operated flight that had a AA flight number and were able to credit that flight for to AS Mileage plan.

A couple weeks ago we did just that. We flew BA operated flights CDG-LHR-LAX and our tickets were from AA. The BA flight numbers were within qualifying range. We did not get the credit automatically which I knew would happen ahead of time. So I submitted copies of our BA boarding passes. A week ago we were asked for a receipt from our ticket purchase so i submitted that as well.

Today we received a response that our request for credit was denied due to the tickets being AA flight numbers.

Have the rules changed recently? Has anyone else had similar experiences recently? Is AS no longer basing mile credit on operating carrier?
