The loyalty partner page has become a sponsor board, built to show how many brands a program has signed. Count the logos and the program looks enormous. Then ask one member which of them she uses.
A consultant flies for work twice a month. Her week runs from a car to the airport before six to a dinner delivered on Thursday, and her airline’s partner page has a logo for almost every hour of it. She has linked three of them. The ride and the gate coffee earn her miles, and so does the card she already pays with.
The program counts its partners, and she uses three. Three is not a sign that the partner page failed. Those three are the partners that reached her week, and they are where a loyalty team should look to learn what a partner is worth.
Loyalty partnerships are measured in the member’s week, and a logo wall cannot show it.
Programs have good reasons to count partners
The count has a job. A long partner list shows the reach of a program and gives members more ways to earn, and American Airlines’ annual report counts more than 1,000 non-flight partners in AAdvantage.
The money explains the rest. An earn partnership, where another brand hands out the program’s points on its own sales, starts with one transaction: the partner buys the program’s currency and gives it to its own customers. Delta’s most valuable contract of this kind is its co-brand card deal with American Express, which paid the airline $8.2 billion in 2025. The American Express money also buys card perks such as lounge access, the use of Delta’s brand, and the right to market through Delta’s customer database.
That is the tension inside every partner page. A new earn partner brings revenue from its first purchase of points, while its value to the member arrives later, and only for the members who use it. The revenue is not the problem. The problem is what the revenue teaches a program to count, which is contracts signed, so the partner report has to add the thing a contract cannot show: what members do after they link.
Recent partnerships start from the member’s routine
The rest of the member’s week happens outside the moments a program already owns, and that is where a partner can reach her. Burger King joined Walmart+ in August 2024, and Walmart said partners help it “extend offerings outside of Walmart’s primary remit.”
Delta has used the same logic twice. SkyMiles members have earned miles on Uber rides since April 2025, which gave a currency to a ride that was already part of the trip. In July 2026 Delta reset its Starbucks partnership so that coffee miles go to members who have flown Delta within the past year. The rule ties the partner back to the airline, because the miles now go to a coffee drinker who flies.
Marriott Bonvoy and Japan Airlines went further the same month. Points and miles already moved between the two programs, and now status moves too: linked Bonvoy members earn credit toward JAL status without taking a flight. Status sets how a program treats a member, so sharing it asks more of both brands than sharing a currency.
Between them, these deals show the five kinds of work a partner can do. Earn partners issue the program’s points on their own sales, and redemption partners accept the points as payment. Transfer partners convert the points into their own currency, the way Bonvoy points become JAL miles. Status partners share recognition, and benefit partners add a perk to a membership the customer already pays for, the way Burger King does inside Walmart+.
Each of these deals takes a routine the member already has and routes it through the program. That is the brief to write before a partner is signed: name the hour of her week it will reach and the core behavior it should lead back to. Loyalty Juggernaut counts the partner network among the engines of enterprise growth for that reason: partners carry a program into the ordinary days its own business never reaches.
A partner earns its place by changing behavior
A loyalty partnership is a second place where the member relationship either grows or wears thin. A partner earns its place when members who see its offers do more of the core behavior the program exists for: more trips, more stays, or more visits.
A partner report can stop at two easier numbers: how many members linked the partner, and how many linked members use it. Linked is not the same as active, and active is not the same as changed.
The research gives reason for caution. One study followed five vendors sharing a single program and found that, for most of them, promotions barely moved sales. Joint promotions were no stronger than single-vendor ones, and no vendor’s promotions lifted sales at the others. A logo on a shared page does little for the logos beside it.
So each partner has to prove its own value, and the way to prove it is a holdout. Before a partner’s offers go out, set aside a randomly selected group of members who will not see them. Compare that group’s core behavior with everyone else’s over the same weeks, and count only the difference, which is the partner’s lift: the extra core behavior its offers caused. Comparing members who linked with members who did not gives only an estimate. Members choose whether to link, and the ones who do were already different. The loyalty program ROI guide sets out the holdout method.
Put that lift beside what the partner pays and what the partnership costs to run, and the partner review finally has a number it can act on. The per-partner scorecard at the end of this essay lays out the six measures in that order.
Partners belong in the finance review and the trust review
This is where the partner conversation leaves the marketing calendar. The price per point looks like a detail for the contract team. Set against the cost per point of redemptions, it is the program’s margin.
Every partner also adds work behind the page: reversals, invoices, disputes, currency conversions, tax, fraud holds, posting delays. That is settlement, and members feel it as the wait for their points. The partner settlement guide walks through the reconciliation.
A partner’s failure can land on the program. In November 2025, Marriott ended its Sonder agreement after Sonder defaulted, and Sonder filed for liquidation days later. Marriott’s first public step was the guests: it said it would contact guests who had booked Sonder stays directly through Marriott channels.
That step matters because members can file a partner’s failure under the program. In one multi-partner retail program studied, members who rated its special treatment as low became less loyal to the program itself after one partner’s service failure.
The quieter risks sit inside the contract, and each has a control a loyalty team can write in. At the largest programs, partner earn is the business model, and status follows it: American’s AAdvantage members earn the Loyalty Points that set their status from co-branded cards and more than 1,000 non-flight partners as well as from flying. The control is the price, so every point a partner buys has to cover what its redemption will cost, and every status point a partner can award has to be priced against what that tier costs to serve. A partner that sells what the core sells can compete for the same purchase, so pick partners that complement the core.
Revenue, margin, member data, and reputation all run through the partner contract. A decision with that reach belongs with the executive team, and finance belongs in the room before anything is signed. Run that way, the partner network becomes part of what makes loyalty an enterprise growth engine, paying the program and leading members back to the core business.
Six tests decide which partners stay
- Start from her week. Map where members spend time and money between the moments the program already owns, because a partner helps only if it reaches one of those hours. For the consultant, the map runs from the car before six to the dinner delivered on Thursday.
- Give her something new to do. A partner should add an action the program cannot offer alone, such as a ride that earns miles. A partner that repeats the program’s own offer adds a logo and a settlement line, and little else.
- Tie the partner to the core. A study of a European airline’s program found that buying from partners fed later purchases of the core service. Build partner earn so it leads back there, the way Delta’s Starbucks rule pays coffee miles to members who fly.
- Measure the lift per partner. Report each partner’s lift against a random holdout, beside what the partner pays, and label linked-versus-unlinked comparisons as estimates. Volume without lift is not growth, because it pays for trips she was taking anyway.
- Price the currency and settle on time. Review the price per point against redemption cost, and posting time against the deadline in the contract. The first protects the margin, and the second protects her patience.
- Write the exit before the launch. A partner can fail fast, and Marriott’s Sonder agreement lasted about 15 months from signing to termination. Decide who contacts members, how long open bookings and balances stay good, and which recognition survives, then sign that plan with the contract.
GRAVTY® shows what each partner’s members do differently
In GRAVTY®, the consultant’s three partners feed one record. Patented multi-dimensional behavior tracking gathers the early car and the gate coffee, the hotel nights and the card spend.
Agentic AI Compass, the team of AI analysts, brings that data together with partner data. It compares members who linked a partner with members who did not, and simulates a new partner offer before launch. The team treats that comparison as an estimate and tests it against a random holdout, so the decision rests on what the offer caused.
Say the evidence shows that coffee miles keep flyers close. GRAVTY Visual Rules, the patented no-code rules engine, lets the partner manager turn that finding into a rule. It takes the shape of Delta’s July 2026 rule: coffee miles only for members who have flown in the past year. AI-Trust flags anomalous earn and redemption behavior as it happens, so the partner review is not the first place a fraud pattern shows up.
GRAVTY® already runs a program built around that kind of week. Emirates Skywards Everyday, an airline’s everyday rewards program, lets members earn and redeem miles across 400+ partners and 2,000+ outlets. The number it reports is activity, not logos: 66% of members active, averaging 12.7 transactions a month.
The partner review that counted logos now asks what each partner changed. Her three stay. Several others leave the page, and nobody who flies twice a month notices they left.
She never reads the partner report
She notices a ride that earns something on the way to the airport. She notices a coffee that knows she flies, and a hotel that recognizes her status from another program. Each one makes the airline a little more useful in the hours between flights.
The partners she ignores cost her nothing. The partner that lets her down costs the program something harder to replace than a logo.
A sponsor board sells space, and a scoreboard records what happened on the field. A loyalty program needs both, and the trouble starts when it reads one as the other.
Programs sign partners. Her week decides which ones count.
The numbers behind loyalty partnerships
These are the partnerships and measures behind this essay. Each figure comes from the company’s own filing or terms, or from a peer-reviewed study.
Six partnerships and the design choice in each
Each row is a design decision another loyalty team can study: which partner type it is, how the earn rule is built, and what value moves between the two programs.
| Partnership | Since | Partner type | The design choice | What moves between programs |
|---|---|---|---|---|
| Delta SkyMiles and Uber | April 2025 | Earn | Earn scales with the ride, up to 3 miles per dollar; UberX earns only on airport rides; Uber Eats earns 1 per dollar on orders of $40 or more | Miles |
| Delta SkyMiles and Starbucks | 2022; new rules announced July 2026, in effect August 5 | Earn, tied to the core | 1 mile per dollar only for members who flew Delta in the past 12 months; newly linked members get 12 months to take that flight; double Stars on travel days | Miles and Stars |
| Marriott Bonvoy and Starbucks | June 2024 | Earn, both ways | Double Stars during hotel stays; 100 Bonvoy points for three purchases in a Bonvoy Week | Points and Stars |
| Marriott Bonvoy and Uber | Terms as of September 2026 | Earn and status | Up to 3 points per dollar on premium rides; Silver Elite for members with an annual Uber One plan; members earn with one partner program at a time | Points and status |
| Marriott Bonvoy and Japan Airlines | Longstanding; status added July 2026 | Transfer and status | 2,000 to 40,000 FLY ON Points a year toward JAL status, by Bonvoy tier, without a flight; matching Bonvoy status for JAL Sapphire members and above | Status, on top of points and miles transfers |
| Walmart+ and Burger King | August 2024 | Benefit | A dining perk inside a paid membership: 25% off one digital order a day and a free Whopper every three months | A member benefit |
The right-hand column shows the range: three of the six carry status or a member benefit.
A scorecard for each partner
Read the rows in order: use first, then lift, then the money and the member’s wait.
| Measure | What it tells the loyalty team | How to count it |
|---|---|---|
| Linked share | How many members connected the partner | Linked members divided by active members |
| Active share | How many linked members use it | Share of linked members with a partner purchase in the period |
| Lift in core behavior | What the partner changed | Trips, stays, visits, or spend of members who saw the offers, minus the random holdout |
| Partner revenue | What the partner pays | Points sold times the price per point |
| Cost to run | What the partnership costs | Redemption cost plus integration and settlement work |
| Posting lag | How long members wait for their points, and whether the partner meets its contract | Days from partner purchase to posted balance, against the contract deadline |
Partner programs in the filings and the research
| Source | Date | What it shows |
|---|---|---|
| Delta annual report | February 2026 | American Express paid Delta $8.2 billion in 2025, up 11%. Delta expects that figure to grow to $10 billion over the next few years |
| American Airlines annual report | February 2026 | More than 1,000 non-flight partners in AAdvantage |
| Study of a European airline’s program | 2009 | Buying from partners fed later purchases of the core service, with effects that varied by partner type |
| Study of five vendors in one shared program | 2011 | For most of the five, promotions barely moved sales. Joint promotions were no stronger than single-vendor ones, and no vendor’s promotions lifted sales at the others |
| Study of a multi-partner retail program | 2014 | When members rated special treatment as low, one partner’s service failure lowered their loyalty to the program itself |
| Sonder filing | November 2025 | License with Marriott signed in August 2024 and ended about 15 months later; Sonder filed for Chapter 7, the liquidation form of US bankruptcy, on November 14, 2025 |
A new partner launches with its exit already written
- Choose the partner from her week. Run the candidate through the first three tests, and name the one core behavior it should change.
- Set the price per point and the settlement terms. Agree who funds the points and what each one costs. The contract sets the payment schedule and the rules for reversals and disputes. It also sets a posting deadline.
- Integrate earn and burn. Decide which way value moves, into points (earn) or out of them (burn), then build the controls into the earn and burn rules. Price partner earn so each point sold covers its redemption cost. Decide whether partner spend earns status, and price each tier’s benefits against the volume that will reach it. Put an end date on any status match.
- Link accounts with her consent. Linking moves data between two companies, so tell her what moves. Marriott’s Uber terms spell it out. As of September 2026, linking means “you consent to Uber sharing your trip or order details with Marriott Bonvoy,” and she can unlink at any time. The same terms let her earn with one partner program at a time, so programs compete to be her pick.
- Measure with a holdout. Before the first offer goes out, set aside a random slice of eligible members who see none of the partner’s offers: 10% in an illustrative plan.
- Write the exit. Name who contacts members, how long open bookings and balances stay good, and which recognition survives. Sign the plan with the contract.
Frequently asked questions
What is a partner loyalty program?
A partner loyalty program lets members earn and use one program’s value at other brands, which gives the program a buyer for its currency and a place in more of the member’s week. The member links her accounts once, and each partner then issues or accepts the currency on its own sales under rules the program sets. Delta’s 2025 Uber deal shows those rules at work: linked SkyMiles members earn on premium rides, UberX airport rides, and Uber Eats restaurant and grocery orders of $40 or more, so a standard UberX ride earns only when it goes to or from an airport.
What are the types of loyalty partnerships?
The five types of loyalty partnership are earn, redemption, transfer, status, and benefit partnerships. Earn partners issue a program’s points on their own sales. Redemption partners accept the points as payment. Transfer partners convert them into their own currency. Status partners share recognition, as Marriott Bonvoy and Japan Airlines do. Benefit partners add perks to a paid membership, as Burger King does for Walmart+. When many brands share one currency and one rulebook, the model becomes ecosystem loyalty.
What is a partner loyalty program in B2B?
A B2B partner loyalty program rewards the resellers and distributors that sell a company’s products, so its rewards are built to help a business sell more. TD SYNNEX, a global IT distributor per its January 2026 annual report, runs one. Its program page offers partners marketing funds alongside paid travel as of September 2026. The guide to B2B loyalty programs covers channel programs in depth.
How do loyalty programs make money from partners?
Loyalty programs make money from partners by selling them points or miles, which partners hand to their own customers as rewards. Delta’s 2025 annual report shows American Express paid the airline $8.2 billion in 2025 under their card deal. The program earns its margin when redemptions cost less than partners paid. The airline loyalty economics guide traces how that sale works.
How do you measure whether a loyalty partnership works?
Measure a loyalty partnership with a holdout: withhold its offers from a random group of members and compare that group with everyone else over the same weeks. Count only the difference in core behavior, such as flights or stays. Set that lift against what the partner pays and what the partnership costs to run. A comparison of linked and unlinked members is only an estimate, because members choose to link.
How many partners should a loyalty program have?
A loyalty program should have as many partners as show lift in a holdout, drawn from brands its members already use and added one at a time. The best count varies by market: a 2026 model in Marketing Science found that optimal program size depends on market composition. Members also split their attention. Deloitte reported in January 2026 that the average consumer enrolls in eight programs and actively uses five, which limits how many partners any one member will notice.
What happens to members when a loyalty partner fails?
When a loyalty partner fails, members lose the ability to earn and use value with it, and the program has to look after the bookings they made through it. Marriott ended its Sonder agreement in November 2025 after Sonder’s default, and said it would contact guests who had booked through Marriott channels. In a 2014 study, one partner’s service failure lowered loyalty to the whole program when members rated its special treatment as low. Write the exit plan before the launch.
