I will note for the forum here on FT that last year around this time the same situation appeared to have occurred. Credits for the UA TB were taking longer than usual and people reported this notion of it being "patched" by AMEX. It turned out that the code they use was just backed up and being updated. Credits posted a few weeks later. While longer than normal we have seen this situation year after year. I will not go as far as to claim this has not been patched because it very well could have been but I would find it odd for AMEX to patch this credit hack a month after the new year (refresh point on people claiming the credit) especially following a massive card refresh in 2025 where if they were to make changes they logically would have done it starting at the beginning of the year. I would implore people to wait the 3 weeks stated for credits to hit the account before determining whether the credit is applied or failed/ "has been patched". If the date people have been reporting as the cut off (2/5 and 2/6) you should wait till the end of FEB to start determining whether the system has patched the UA TB. AMEX does typically deliver these credits quickly but keep in mind that because JAN 31st is the day people need to choose the airline credit.... early FEB typically overloads the system scanning for what purchases to credit. Again, not claiming something with this comment but just providing context that can help clear up information we can't confirm yet.
