Courtesy of New Girl in the Air – Wow! You can get FREE Hilton Gold status for 15 months! Gold status will get you bonus Hilton points, plus free upgrades, free breakfast, and free internet at most Hilton properties. Just register for this promo. When it asks for a code to verify your credit card, just use 411945. It doesn’t seem to matter if you actually have a credit card at all! If you don’t already have a Hilton membership, sign up for one for free then register for this promo!
UPDATE: As of 12/28, this no longer seems to be working. Often when you see an opportunity like this you have to jump at it quick!
UPDATE: On 12/31, I read on another blog that people are now having success using the code 442394.
