I wasn't sure where to dump this, so you guys can throw it where it needs to go. I just wanted to post it to prevent anyone else getting as frustrated as I did.

I loaded up my account with 149,000 miles, woke up super early and booked suites on SQ12, NRT-LAX. When I got to the credit card page, I entered it in, there was a hold on my CC, but I got a technical error. I called and they said "Someone booked it, you took too long." I tried another day, took 3 minutes to do it, but got the same result. Frustrated and fed up, I called. The guy informed me that I had 5,000 miles that should not have been in my account. Back last year, there was a promo for 5,000 free Singapore miles, which I used. Because these miles were for Singapore Airlines Australia, they should never have been in my account, therefore I technically didn't have enough miles.

The representative put in a help ticket to reverse the miles out, reserved my ticket, and instructed me to transfer another 5,000 miles. I transferred them in and am waiting for the reversal (it started on Friday). They said my ticket is reserved, my seats are assigned, and I can see my booking on the website. Once the miles reverse, they'll send me a confirmed ticket.

Just wanted to throw this out because it was really, really frustrating. Those "free miles" promos actually can hurt sometimes. Stupid me for not really reading the terms. Lesson learned...
