Quick update: After several rounds of emails, Marriott's customer service has explained to me that it is completely normal that my 2025 upgrade awards will turn into 2024 upgrade awards because I have received them in January 2024. Be careful! I'm very disappointed in the lack of consistency. I'm also afraid this might happen to other certificates as well that are currently valid until December 2025 and which I'm planning to use sometime next year.
HTB.
You earned your 50 nights on Janaury 3, 2024?? Because thats the only way youd be getting 5 NUAs with 12/2025 expiration date.
Also with NUAs not automatically returning to your account after booking has been canceled is a known IT bug. Happened to me more than I care to count. Just calling in will fix that. Some agents say it will credit back to your account after a few days. That's a lie. HUCA or escalate to get back on the spot.
