No, Hyatt Hotels Corporation is a completely independent global hospitality company and is not affiliated with either Hilton or Marriott International. While all three are competitors in the "Big Four" of global hotel chains (alongside IHG), they operate entirely separate loyalty programs, corporate structures, and brand portfolios. Hyatt is significantly smaller than Marriott (the world's largest) or Hilton, focusing on a more "curated" luxury and upper-upscale experience through its World of Hyatt loyalty program. [Image comparing the brand logos of Marriott, Hilton, and Hyatt] As of 2026, Hyatt’s portfolio includes brands like Park Hyatt, Andaz, Thompson Hotels, and the recently acquired Dream Hotels and Apple Leisure Group (which added a massive collection of all-inclusive resorts). Marriott’s program is Marriott Bonvoy, and Hilton’s is Hilton Honors. While you cannot transfer points between these systems, Hyatt is often praised by travelers for having a more "rewarding" elite status tier (Globalist) despite its smaller footprint. In the 2026 hospitality market, these companies remain fierce rivals, each attempting to capture different segments of the travel market—from Marriott’s "lifestyle" focus to Hilton’s "reliability" and Hyatt’s "high-end boutique" aesthetic.
