Summer is peak travel season, so hotel and airfare prices climb across the board. For loyalty players, though, that same peak season is the best window all year to bank points and miles cheaply. Right now Marriott Bonvoy and United MileagePlus have teamed up on a summer-only dual-currency offer, and the entry bar is refreshingly low: one paid Marriott night plus one paid United flight earns you both hotel points and airline miles. If you’re already booking Marriott stays and United flights this summer, it’s close to free money — but 2026 quietly changed one rule that trips up returning players every year.
What Is the Marriott United Summer 2026 Promotion?
The mechanic is simple: complete one set of a paid Marriott stay + a paid United flight and earn 2,000 Marriott Bonvoy points + 1,500 United MileagePlus miles. Sets stack, so more aligned trips mean more rewards.
| Detail | What to know (all times EDT) |
|---|---|
| Registration window | July 1 – August 31, 2026 |
| Eligible travel period | July 15 – September 30, 2026 (stays by check-in date, flights by departure date) |
| Reward per set | 2,000 Bonvoy points + 1,500 MileagePlus miles |
| Posting time | Up to 12 weeks after the promotion ends |
One prerequisite catches newcomers off guard. You must first be enrolled in the Marriott × United Preferred Partnership Program, and enrollment is only open to Marriott Titanium/Ambassador Elite members or United Premier Gold, Platinum, or 1K members. Enroll first (via the official Marriott offer page or united.com/MarriottBonvoy), then register for the offer. Timing is generous — even trips booked before the promotion, or already completed, still count, as long as travel falls in the window and you register by August 31.
Rules, Traps, and the Smartest Way to Stack
This promotion only recognizes pure cash spend. Four hard conditions must all be met:
| Requirement | Must be |
|---|---|
| Airline | A flight actually operated by United / United Express (codeshares on partner metal don’t count) |
| Fare | A paid cash ticket (award or cash-and-miles bookings are excluded) |
| Account | Your own MileagePlus number on the flight |
| Room | A paid Marriott room, minimum 1 night (award or points-and-cash nights are excluded) |
Two traps hide in the fine print.
First, stays count by check-in date, so a September 30 check-in with an October checkout still qualifies.
Second — and by far the most common miss — your Marriott earning preference must be set to points, not miles. If your account auto-earns airline miles, you get nothing even when everything else is perfect. Verify it before you register.
Now the biggest 2026 change: rewards settle per stay, not per night. In past years miles stacked by nights, so a five-night stay paid five times. This year, one continuous stay — whether 1 night or 5 — counts as a single 1,500-mile set. The workaround for heavy earners is to split one long stay into several shorter bookings, each paired with its own flight. Two caps also apply: you only earn on the lower of your flight count vs. stay count, and you can join just one Dual Currency campaign per calendar year.
In short: cash flights, cash rooms, and match the number of stays to flights.
Fast-Track the Elite Status That Makes These Stays Pay More
Here’s the strategic angle. This promotion pushes you to book paid Marriott rooms all summer — and paid rooms are worth far more when you hold Marriott elite status. This is especially true if you’re qualifying through the United side and hold no Marriott tier: every cash room you book for this offer is leaving value on the table.
