Update: It affects all brands (e.g American Airlines, Expedia, Hilton, Citi ThankYou Points). Can't edit title so if a mod can that would be great.
Citi TYP earning cards now read:
Bonus ThankYou points are not available if you have had ThankYou Preferred, ThankYou Premier or Citi Prestige cards opened or closed in the past 24 months.
Previously it was on a card by card basis, now these three cards are grouped together.
