Congrats on your Citi AAdvantage Executive approval
Congrats on your Citi card and a very nice SL
Congrats! I went ahead and decided to go with the Executive card last week. My travels have led me to more Admirals clubs than anything else this year and the AMEX Plat still doesn't entice me to go back so in considering that coupled with I fly AA, no brainer. Got the exact same SL, wth? haha! Now what to do with my existing AAdvantage Platinum Select World Elite card, PC to something but not sure what.

@sophiebelleThats interesting. I got my Citi Executive card back in July and I got the identical credit line.
Congratulations on your CITI AAdvantage Executive approval and nice SL, @sophiebelle! 
Yes, there's something going on with that $30.5K limit that @MarkintheHV reported. I noted his approval was the same as mine, which was also $30.5K last October. That same limit was also reported by DoctorLoomis in May. That makes four of us in less than a year with an odd-number $30.5K limit.
I recon'd the approval and took another HP to get $5K more within 30 days (to $35.5K) and then got another $7K at the six month to bring me to $42.5K. 
It's a very nice card and data points seem to indicate it grows well. Here is a link also to my unboxing thread. For premium card enthusiasts, this is now CITI's heaviest metal card available and in the same weight-class as the AMEX Platinum.
I got it at the old AF of $450, but they've already started crediting me monthly on GrubHub purchases per the new higher AF/new credit system they implemented in July this year.
I've enjoyed the Admiral's Club access with the card on my AA travels. I hope you'll enjoy it too!
I only fly American and have managed to get EP for the past couple of years and I'll get it again this year, but I don't think I'm going to hit 250k LP's to get Admirals Club for free again.
The AMEX situation is real. I just paid my annual fee plus the extra for the AU and it just keeps getting more difficult to justify carrying this card as time goes on. I also have the Chase S.R., so carrying 3 cards now with "high" AF's is probably too much, but I have to decide to ditch one just not sure which. I fly out of DFW a lot but rarely in D terminal to enjoy the Centurion Lounge over there and I'm really just as happy in the Admirals Club and I run into them a whole lot more (STL, TPA, ATL and DFW are my frequent airport visits).
First world problems, I guess.
I also have the Platinum Select, but I am going to PC to Citi Custom Cash once my upcoming statement hits. I'd rather just give up a $200 intro bonus vs. having a new credit card hit my credit report.
I did get my card in the mail today and set it up. It's saying 100k miles for 10k spend by Dec. 18th. If this turns out to be true, then this is even better!
