I was wondering how long it takes for the bonus from various airline CC's to post. I know what their terms and conditions say, but I was wondering what the actually observed time frame is like. I was wondering for the Citi AA MC, the Chase United Visa, the Delta Gold Amex, and any other cards. After the purchase requirements are met ($750 in purchases for some cards, any purchase for other cards), how long does it take for the bonus to post? Thanks for any info.
