Yeah, flying my family of 5 to Hawaii using skymiles accrued on my Amex. Totally a scam.
They’re basically interchangeable with cash. I don’t get the issue. The main frustration I have is that I cant buy myself a ticket with cash and then pay skymiles for my child. If they weren’t of an age that they must be on the same reservation it wouldn’t matter. Feels more like a limitation of Delta’s abacus that sits behind their mobile app.
