I have some Diners Club points to transfer, so I looked on the DC site and it says it may take from two to six weeks. Since I use the card a lot, I'd like to know I don't have to transfer points in mid-October and miss out on six weeks worth. :)

Yeah, I think there are a lot of people in that position, trying to get point totals as high as possible before making the transfer. It would be nice if we could get a definitive answer from AA. My personal opinion is that the logistics of trying to incorporate backdated mileage deposits into the MM total after 1 December would be pretty obnoxious. I think it would be far easier for AA's computers to just reset on 1 December and that's that. So I suspect that backdated things aren't going to count, unfortunately.

They routinely back date bonus points, so I think they will. We shall see. :)

Well, this is one of those times when I hope you're right and I'm wrong! :D

P.S. I'm currently at 1.936 :p

I'm falling behind. 1.893 :(

In practice these transfers take 48 hours, see here:

Be aware also that AAdvanatge will leave Club Rewards when BMO/Harris Bank assumes full control of the Diners Club USA franchise. See here:

Again, not to thread hijack, but...

I just got hit with my Citi AA renewal fee (standard card, $85 I think), if I were to call Citi and threaten to cancel (SPG card is a better value now, even for purely earning AA points only for flights and not for any status objective as I'm EXP annually), in anyone's experience will Citi try to compete, offer bonus points, lower the fee? I did get some bonus points match earlier this year when it was available to match new customer offers.

Why? Miles know the date they were posted, so...

if (miles->posted_date < DEC_1_2011)
total_miles += miles->count;

not that hard.

This is AA's antiquated IT we're talking about ;)

I doubt that miles know the date they were posted on. This would involve a data structure with at least two elements per mileage transaction as opposed to a simple accumulation store. I doubt that they have the proper data structures for this.

Cheers.

While I don't suggest that every mile know where and when it came from, if you pull up AA.com, you can see the date that a given set of miles were posted on (and this history goes back), so clearly this information is recorded.

But yes, your "program total" is likely just a counter, however it would be trivial to look at the posted date when adding those miles to your account.

Two basic ways to do this. Either a data structure where the miles have some knowledge of when they arrived, or a rolling ledger sort of thing where the miles know nothing and the ledger just keeps records of dumb miles, and the scroll off after 6 months or so to be stored in paper records. I'm counting on the latter.

Cheers.

When they're posted, the information about the postdate is presumably available since that information is displayed for you, and they could decide whether to increment the program total (MM) mile count based on that. Of course, even if they could, we don't know if they will, but my point is they could.

Of course, I'm just speculating based on previous mainframe work I've done, and what data AA.com seems to have.

There is a whole thread about this very topic. But in general, yes, Citi will waive the annual fee or give some form of bonus miles, or both.
