IAC Awards

Best Hotel and Lodging Integrated Ad Campaign

Flemings Hotels clinched the “Best Hotel and Lodging Integrated Ad Campaign” award at the 2023 Internet Advertising Competition, hosted by the Web Marketing Association.

Their triumphant “Black Week” Pre-Holiday Bookings Campaign, powered by Amadeus GMS Solution, ingeniously incentivized both members and non-members to join their loyalty program.

The campaign deployed targeted marketing emails, promotional banners on their iHotelier® Booking Engine, and pop-up ads on their Amadeus Web Solutions homepage.

This strategic move led to a remarkable 109% growth surge compared to their summer campaigns and an impressive 98% Return on Ad Spend (ROAS) in just two weeks!
