In the world of loyalty promotions, it rarely happens that you can earn points on both sides Without having to give up anything.

But this is exactly the case with the new initiative jointly launched by Marriott Bonvoy e United MileagePlus: a promotion that allows you to get extra points and miles For each hotel stay and each flight made by August 31, 2025. All with an additional bonus for those who complete both activities.
An attractive proposition for those who have already planned summer trips-perhaps taking advantage of some flight deals-and want to maximize point earnings, Without changing one's habits And without spending a penny more.
What is the double dipping (and why frequent flyers love it)
In the jargon of loyalty programs, the double dipping is the practice - perfectly legal - of Get rewards from two programs at the same time for the same activity. For example: book a Marriott stay and receive both classic Bonvoy points either miles United for the same night. Or fly with United and earn both miles MileagePlus which points Marriott Bonvoy as a bonus.
In times when many programs have reduced benefits and made accumulation more difficult, double dipping has become a key strategy for those who want to maximize the benefits without complicating their lives. And it is precisely on this mechanism that the Marriott-United promotion is based.

- Register for the promo on the Marriott or United website by August 31, 2025.
- Complete at least a paid stay at a Marriott Bonvoy facility and/or a paid flight operated by United Airlines.
Here is how bonuses are awarded:
- 750 Bonvoy points For each qualifying United flight
- 500 MileagePlus for each qualifying Marriott stay
- Extra bonuses by 1,500 Bonvoy points + 1,000 MileagePlus miles if you complete at least a flight + a stay during the promotional period
