I called citi to inquire and see if they have something in the grapevine to "replace" the 15% discount and companion benefits. Turns out I got a supervisor for the Prestige customer service team and this was the first time she heard about this cut.
The super agrees that these two benefits are huge (probably the biggest benefit behind the $200 statement credit IMO) and hopes Citi will come up with something to replace both benefits.
