I'm really behind so you may have updated this since you first posted...I haven't heard back on my SM about a match to a higher offer yet on my AA biz. I also haven't bought the $250 gift card yet (which will be reimbursed)...but I will report back on both when I know more!
I asked for a match on my pers AA right around when you did yours (I know yours was biz) and I got the letter yesterday saying they would deposit 20,000 points into my account. So we shall see. Fingers crossed for you, I am sure you will hear soon!
I am hoping to get the credit on taxes/fees paid on points flights. I will admit that this card/app was one of my least thought out ever, so I have no idea if that will credit. Worst case I'll buy gcs, I could use those too.
