Hilton made an announcement back in April (access here) that they would be moving away from yearly award category changes and would adjust award categories “seasonally” that seems to mean monthly. There were quite a few changes last month (read more here).
Hilton HHonors has just updated its web page where they post these changes. I doubt that they would email Hilton HHonors members about these “enhancements”.
You can access Hilton’s web page for these changes here.
You have to bear in mind that Hilton’s award categories don’t mean as much as they used to because the number of points within an award category varies a lot per the table above.
Hotels Decreasing In Award Category
Hotels Increasing In Award Category
There are 12 hotels moving down in award category and 20 moving up. I have covered the Hampton Inn that moves from category 1 to 3 on my earlier Hilton HHonors award chart upgrade post.
