A LoyaltyLobby reader dropped me a screenshot of the message that had popped up on his IHG app messages.
I have previously written about birthday bonus points that IHG Rewards Club seems to be extending to some members (I have never received them).
You can access IHG Rewards Club here.
Noe that you can have your birthday info on file with IHG that must be one of the requirements to get this message.
Seems that IHG Rewards Club is extending this birthday bonus to some members. Not sure if having an IHG app is now required. I believe that previously this came though via email.
