Just called to check the status of my Amex Hilton Honors application. The rep completed it and approved me over the phone. The limit isn't much (2K), but I will transfer some of the line from my Blue to this account after I receive the card. In the last two months I've been approved for Discover Gold, Diners Club Montage, Citi HHonors Visa Signature and now the Amex HHonors card. The bad news is that I'm loaded with inquiries now (6 in the last 6 months) so I'll have to wait some time before applying for anything.
