Marriott Bonvoy + United MileagePlus Promo 2025: Earn Double Rewards on Summer Travel

If you're flying United or staying at a Marriott this summer, there's a limited-time opportunity to earn bonus rewards in both programs. Through August 31, 2025, Marriott Bonvoy and United MileagePlus are offering a special promotion for elite members who register and link their accounts.

TL;DR

• Earn 750 Marriott Bonvoy points on eligible United flights
• Earn 500 United MileagePlus miles on eligible Marriott hotel stays
• Complete both and earn a one-time bonus of 1,500 Marriott points + 1,000 United miles
• Must register and travel by August 31, 2025

How the Promo Works

Marriott Bonvoy and United MileagePlus have teamed up again to reward travelers who engage with both brands. This summer, you can "double dip" and earn bonus rewards across programs:

• Flights: Book and complete a cash United or United Express flight by 8/31/25 to earn 750 Marriott Bonvoy points per eligible itinerary (in addition to normal MileagePlus earnings).
• Stays: Book and complete a paid Marriott Bonvoy stay of at least one night by 8/31/25 to earn 500 MileagePlus miles per eligible stay (on top of standard Bonvoy points).
• Combo Bonus: Complete both at least one flight and one hotel stay and you'll receive a one-time bonus of 1,500 Marriott points and 1,000 United miles.

Note: Bonus points and miles may take up to 8 weeks to post after completing qualifying travel.
