If you have a Chase card, like me:
The credit card has a closing date each month. Normally, you'll see the points from your purchases, within a few days after closing. When you stay at a Marriott property, you'll get 5 points for every dollar, including tax. You'll get 2 points for every dollar spent at restaurants, on airline tix, and renting cars. Then of course, you'll get 1 point for all other purchases.
I'm curious, did you just sign up for the credit card and it's 80,000 points bonus? If so, the T&C mention three months and $3000 spend to qualify. It also states 6-8 weeks after meeting the threshold for the points to be deposited.
Good luck and welcome to Insiders.
Give Chase a call. There should be a number on the back of your card.
By the way, I track all my stays and spending online at Chase. I have never caught an error. The only issue I've ever had was a day or two delay in points posting to my Marriott Rewards account. Honestly, I think the issue was on Marriott's side, not Chase.
