Marriott Worldwide has been granted the trademark for the Bonvoy figurative logo below that I assume that we should soon start seeing instead of Marriott Rewards/SPG/Ritz-Carlton Rewards.
Marriott briefly had their production web page door left open with the Bonvoy name featured and they had applied for the regular trademark earlier for this name.
You can access Marriott Rewards here.
Conclusion
Difficult to get much excited about the made up word “Bonvoy” that must come from “bon voyage” in French that means good voyage.
