Amex Offers $100 Cashback for SLH Stays Over $300 Between Sept 1 - Nov 15, 2026

American Express has launched a new offer for select cardholders to earn $100 in cashback when they spend at least $300 or more at participating Small Luxury Hotels of the World (SLH) properties between September 1 and November 15, 2026.

The offer is only valid on room rate and charges made directly with SLH online, excluding prepaid bookings, gift cards, and amenities. Cardholders must enroll in the offer through their American Express account and use the same enrolled card for qualifying purchases.

A PDF list of participating properties can be accessed by clicking on a link provided in the source. One potential workaround mentioned is booking through Hilton Honors for one of the listed properties, as long as it's made directly with SLH and not prepaid.
