United Mileage Plus elite members who stay at any Hyatt worldwide property can earn 2,500 miles per stay through Jan. 31, 2011 (that’s right, 2011, so you have a lot of time to rack up those extra miles through Hyatt stays). Members normally earn only 500 miles per stay so each stay will bring in an additional 2,000 miles. Provide your Hyatt Gold Passport and Mileage Plus account numbers at reservation and check-in to earn the bonus and make sure you choose Mileage Plus miles as your earning preference. Hyatt brands participating in this offer include Park Hyatt, Andaz, Grand Hyatt, Hyatt Regency, Hyatt Place and Hyatt Summerfield Suites. Registration at http://insideflyerus.wpengine.com/link/?2129 is required and Mileage Plus members must have elite-level status to be eligible.
