I got the citi Executive AAdvantage world mastercard with 100K bonus last week. Wanted to apply for another AA card to increase miles for a flight from US to paris this summer. Looking at Citi Platinum select mastercard with 30K bonus for personal or Citibusiness mastercard with 30K bonus for a business card.

How long do I need to wait to apply for another card since I just got one last week? Gotten different answers on other forums as far as how far to space these out before re-applying. Am I more likely to be approved for a business card since I just got a personal card from citi or does that matter? Thanks for any advice.
