Quick thoughts
As we’ve seen before, this is a win-win for eligible Bonvoy members and eligible MileagePlus elites because all the earnings from this promotion are just a bonus on top of any regular earnings that travelers would have accrued anyway when they stay with Marriott or fly with United.
Clearly, the bonuses on offer don’t represent a material rebate of any sort (we value 500 United miles at $6.00 and 750 Bonvoy points at $4.50) so there isn’t much here to encourage anyone to make any new booking, but the bonuses will no doubt be welcomed by anyone who was already planning an eligible stay or flight.
Before you register, however, be aware that the terms of this offer clearly state that anyone registering for this promotion will be ineligible for any other similar promotions that may or may jot be offered this calendar year.
With that in mind, I would advise not registering until just before you’re about to make a qualifying stay or book a qualifying flight as it would be a shame to disqualify yourself from any potential future earnings this year because you registered speculatively and then didn’t end up with any qualifying activity by 31 August 2025.

Bottom line
Through 31 August 2025, select MileagePlus elites can earn 750 bonus Bonvoy points for every qualifying Marriott stay and select Marriott Bonvoy elites can earn 500 bonus MileagePlus miles for every eligible United Airlines booking.
Eligible elites completing an eligible flight and an eligible stay during the promotion period will also receive a one-time bonus of 1,000 United MileagePlus miles and 1,500 Marriott Bonvoy bonus points.
Note: Not all stays made with Marriott and not all bookings made through United Airlines will qualify for this promotion so make sure you read the terms and conditions carefully before you set your expectations.
