@hummelav Do you want the trivial stuff?
U can go to hang out in plaza premium lounge at the airport with the new credit card and drink free coffee and eat free breakfast
You can...call dedicated hotline at your bank and maybe they will pick up your phone 2 seconds faster than then plebeian phone number
Got discount at the golf course, some hotel chains. If you T1, exclusive access or concierge services when you travel
And um, sometimes banks give u a car sticker so you can get priority parking
You get...uh nicer angpao from your bank if you maintain RM250,000 or above
Other than the obvious advantages which are entirely personal i.e. being able to help monetarily with friends and family, being out of debt, being able to invest, financial freedom etc.
