Check Your Hyatt Points Balance for Extra or Missing Points
If you have earned Hyatt points or used them last month, check your accounts for unexpected changes in your points balance. There are a few reports of people seeing extra points posted to their Hyatt accounts.
One reason that is suggested for these points, is that Hyatt is doubling all the transactions that happened in May. So if you earned 10K points for example, you might see an extra 10K posted your account. This apparently is happening for redemptions as well, so you might be missing points.
Not sure how widespread this is, but take a look at your account and let me know if you notice anything unusual in your balance. I would thing that this is a glitch that should be fixed soon, but it might affect you temporarily if you need to redeem points.
