Starwood Preferred Guest (SPG) Credit Card from American Express holders: Call 1-888-625-4990 and mention code UI to get a free upgrade to Gold status. If not approved, try again to reach a nice one.

Gold Status benefits:

• Earn Free Night Awards faster. Increase your rewards to 3 Starpoints for every eligible U.S. dollar spent -- a 50% bonus over Preferred Guests.
• Enhanced Rooms. Rather than redeeming Starpoints for a better room, you're entitled to an automatic room upgrade at check-in when one is available. An enhanced room includes rooms on higher floors, corner rooms, newly renovated rooms, or rooms with preferred views1.
• 4 p.m. late checkout, when available
• Gold Preferred Guest® special customer service telephone. Access number for reservations and information: 888-625-4990
