I currently have both the Gold and Platinum Delta - there is no real reason to have both, and I would like to use the Gold slot to apply for another Amex card. I have had the Gold card for 14 months, and I paid the annual fee already. Is it safe to cancel this card while preserving the ability to get new sign up bonuses? I have not cancelled any other Amex card. Basically, I am looking for data points of people that have cancelled Amex cards in recent months and have received sign up bonuses subsequent to the cancellation.
