Free 1,500 Starwood Points

Now through March 31, 2015, you can earn 500 bonus Starpoints per stay, up to 3 stays, for booking via the Starwood app, and also using an American Express card.

All stays must be completed by March 31. Though clearly not as lucrative as Hyatt’s 1,000 bonus points per booking made via their app, it’s an easy way to pick up an extra 1,500 Starwood points. Redemptions start as low as 3,000 points, so this is halfway to a one-night stay at one of their low-level properties.

Here are the terms and conditions: Registration and Earning: Members must register online with a valid SPG account number at spg.com/appamexbonus by March 31, 2015, midnight Eastern Time (ET). Registered members, who have downloaded one of the SPG mobile apps, are eligible to receive 500 bonus Starpoints for up to three booked and completed stays December 10, 2014 and March 31, 2015 (the “promotion period”) that were booked through any SPG mobile app and charges were settled with any American Express® Card. Bookings made prior to the promotion period are eligible, but only eligible stays consumed during the promotion period will receive bonuses. Check-out must occur on or before March 31, 2015 to be eligible for bonus Starpoints. Registered members may earn a maximum of 500 bonus Starpoints per eligible stay, and maximum of 1,500 bonus Starpoints during the promotion period. This bonus is eligible at all properties that participate in the SPG program.
