Was looking for a way to use hotel points for the upcoming trip and ended up getting a very nice deal in Cat 2 SPG property (my first SPG point redemption). Afterwards I've then decided to do some reading and most travel bloggers push SPG card saying that the bonus is valuable due to the ability to transfer those points to the airlines. Doing some quick math, assuming one got 35k bonus after $5k spend and ended up with 40k SPG points best case those miles transfer to 50k AA/UA miles...which is an everyday offer for the respective Citi / Chase cards. Am I missing something?
