Hyatt Gold Passport has a new promotion for ANA Mileage Club members for double miles (500 base +500 bonus) for stays between December 1, 2013, and February 28, 2014.
There is no need to register for this promotion, but you need to use offer code AN660 at the time of making the reservation.
You can access ANA’s web page for this promotion here (couldn’t find anything on Hyatt.com) and Hyatt’s web page here for information about earning miles for your stays.
Conclusion
Seems that Hyatt has numerous promotions for double airline miles during the winter time. This likely indicates that there won’t be a global promo for bonus Gold passport points before February at the earliest.
If you make the booking using the Hyatt link above, you are supporting LoyaltyLobby at the same time.
