Citi is offering me the Citi Select Amex card (I already have the visa signature version). The starting bonus is 25k miles. I probably plan on keeping the AA Platinum Visa for ~6 more months before closing it. Would I would be losing any future offers if I took this one. Is it possible to get them to bump up the bonus miles to comparable to a new card?

Another question I have is the card is pre-approved, if I apply will there be another credit pull?

Are they offering an Amex-network card on the same billing account a discussed in this thread:

...or are they simply inviting you to apply for an additional account?

Another card on the same account should not involve any credit pull because there is no new account, no new risk.

You will be hit with another hard credit pull. It happened to me.

Yes, you will be losing out on all AA future offers for probably 18 to 20 months. That is the time you have to wait between successful Cit AA applications (not counting special invitations like the one you got).

(Plus you can only submit two Citi card applications in any 65days between any Citi card applications, AA or not, successful or not. Try more or more often than that, and you're guaranteed to be denied, and then have to wait yet another 65ish days.)

And you can probably apply for two (2) Citi AA cards every 20ish months, but only if you apply for both on the same day (preferably the same hour), for safety using two different types of browsers (eg, one card in Firefox, the other card in IE) to avoid the system getting confused between your two applications.

(But if you wait a day or more between the two apps, the second app will be certain be deined! That's why it's so important to decide ahead of time which offers you want to apply for and whether you'll apply for one or two at a time.)

And there are way better offers out there than 25k per card. See these threads in MilesBuzz!:

Very unlikely. It's Chase that does bumps left and right, and still only when you apply for a new card, just not the new card with the best bonus, and then later you hear about the better bonus. (And they tend to have a few month time limit on it.) I don't recall hearing of anyone getting a successful bump up to a better bonus at Citi (the only bank that does AA cards).

Citi lets you apply for two cards at the same time, which IMHO more than makes up for the lack of "bumps", but it does mean you have to plan better at Citi than at Chase.

Thanks for feedback, I think I will skip this offer.

I thought it was around 12-18 months after closing the account?

It was a popular refrain in the thread where this post first appeared, but it's applicable here too: Read Post #2! http://www.flyertalk.com/forum/14386923-post2.html.

The clock is based on application date, not account closing date. And it's one of those weird mystical credit card things, there appears to be no hard and fast rule. Some people were getting approved just 12 months after previous apps, but those reports have died off recently. Many people get approved after 18 months, but others are denied. 20 months seems to be the safe line at the moment.
