Hilton HHonors today updated its website with “Track My Offers” that you can access using the “My Offers” link on the account page (access here).
The page should now show all the promotions that the member has signed up for (it doesn’t) and it should later show all eligible offers that member could sign up for (don’t think that it will).
You can access Track My Offers here.
My Active Offers:
This should list all the offers that I have signed up for that is not the case. All the airline ones are missing.
My Eligible Offers:
This will list eligible offers sometime in late 2016.
Marriott and Starwood have both had something similar for a while and IHG Rewards Club has online promotion tracking as well. It is about the time for the Hilton to offer something similar.
I doubt that the “My Eligible Offers” tab would ever show all the airline promotions that you are eligible for. You cannot even easily find them on Hilton’s website currently.
