Hilton HHonors members earn 1,000 bonus miles with United Airlines Mileage Plus for each stay of two or more nights from October 1 to December 11, 2011. Up to 5 stays for 5,000 bonus miles may be earned during this promotion for Points & Miles earners choosing either Points & Fixed Miles or Points & Variable Miles. These bonus miles appear to me to be additional to standard miles earned for HHonors stays since terms state the bonus miles will post after promotion ends. Registration required at www.hhonors.com/mileageplus Promotion T&C To be eligible for this offer, you must (1) select United Airlines as your preferred Double Dip® Points & Miles Partner in your Hilton HHonors™ account profile, (2) complete a minimum 2-night stay at a participating hotel or resort in the Hilton Worldwide portfolio from October 1, 2011 through December 11, 2011, and (3) register online at www.HHonors.com/MileagePlus prior to check-out. You must be a Hilton HHonors member to earn points and miles for hotel stays. Bonus United Mileage (Both Fixed & Variable Miles Members): Earn 1,000 bonus miles per qualifying stay of 2-nights or more, for a maximum of 5 stays or 5,000 miles. Allow up to six weeks after qualification, and after promotion has ended, for bonus miles to be credited to your account. Miles accrued, awards issued and bonus offers are subject to the rules of the United Mileage Plus program. Hilton HHonors membership, earning of Points & Miles™ and redemption of points are subject to HHonors Terms and Conditions.
