The Citi ThankYou Premier Card is now offering 50,000 bonus ThankYou Points after $4,000 in purchases within the first 3 months of account opening. For the majority of 2016 the ThankYou Premier had no sign up bonus whatsoever, then Citi came back with 40k points for a $3k minimum spending requirement bonus in December 2016.

Citi issues lots of cards that earn ThankYou Points, but not all of them earn a type of Thank You Point that can be transferred to airline and hotel loyalty programs partners like the Citi Prestige and Premier cards do.
