I applied last week under the 18 month language! I was instantly approved, but FML! I have a feeling Citi is not going to honor it when it comes time to posting the certificates.
I haven't even got the card in the mail yet. I know for a fact it said 18 months because I was specifically looking for the language.
It's been about 22 - 23 months.
I specifically wanted to make sure I was months past the 18 mark since Citi doesn't always calculate properly. Now I wish I would have waited just a few more months!
