3월 28일부터 전산 통합 시작한다고 이메일이 조금 전에 날아 왔더군요. 

On March 28, we'll begin moving Dividend Miles^® members into the AAdvantage program. This transition to a single loyalty program will take several days. 

We’ll send you more details about the benefits you can expect as soon as everything has been completed. 

Thank you for your continued loyalty and for flying with us.

이제 드디어 시작이군요. ^^
