WIKI Important limitation on these offers: "Hilton HHonors Bonus Points offer not available if you have had a Citi Hilton HHonors Visa Signature Card account that was opened or closed in the past 18 months."
HAVE FOUND "Hilton HHonors Bonus Points offer is not available if you have had a CitiŽ
Hilton HHonorsTM Visa SignatureŽ Card account that was opened or closed in the past
24 months
Looks like changed the rules to 24months or maybe once a life time
