We stayed at Hilton during the recent promo period in November. The room was paid for with my credit card but we provided my husband's ff # because he is in need of these miles to reach elite status. We also provided our joint Hilton Honors #. Everything posted okay on the Hilton site but when they posted to NW, it says "name mismatch." Prior to contacting NW, can anyone tell me what we did wrong? Is it not possible for him to get credit because the room was paid for with my card? (We really need these miles for him to become elite!)
