Mileage credit missing No Boarding Pass
I flew on LAN/TAM from COR-AEP-GRU-CDG-GRU-AEP-COR on 6/6 returned on 7/6. All mileage posted to AAdvantage except for return from CDG to AEP. At first the TAM legs from Buenos Aires to Paris didn't post but after submitting a request to AAdvantage all but the CDG-AEP return hasn't posted. So AAdvantage asked me to submit ticket and boarding passes. On 7/20 I responded by attaching the ticket and explaining that I didn't keep or can't find the boarding passes. I haven't heard anything more. Am I out of luck if I can't find my BP?
