Loyalty points don't just come from flights, hotel nights and credit card spending. Airlines and hotels have quietly built webs of partnerships with everyday brands — coffee shops, ride-hailing apps, fuel stations, holiday rentals — and linking your accounts usually takes a couple of minutes and costs nothing. If you're not doing it, you're effectively paying full price for things you could be earning rewards on.

Delta has one of the richest everyday-earning setups. Link your Starbucks Rewards account and you'll collect one SkyMile per dollar spent at Starbucks, plus double stars on days you fly Delta. Uber rides earn between one and three miles per dollar depending on the tier — Reserve rides pay the most — while Uber Eats restaurant and grocery orders add another mile per dollar. Even Airbnb counts: one mile per dollar on qualifying stays and three on experiences and services.

American Airlines AAdvantage members can earn three miles per gallon of fuel at Shell by linking to Shell Fuel Rewards, plus miles on rentals across most major car hire brands, with elite members and some cardholders getting up to five miles per dollar at Avis and Budget. One thing to watch: the AAdvantage–World of Hyatt partnership is winding down, and members need to link accounts by 15 November 2026 to keep earning Hyatt perks through February 2027.

United leans on Lyft — up to four miles per dollar on scheduled airport rides — and its RewardsPlus tie-up with Marriott lets elite members convert miles to Bonvoy points at 1:1, with bonus miles on larger transfers. Vrbo bookings earn three United miles per dollar. Hotel-side, Hilton Honors pairs with Lyft for three points per dollar, and World of Hyatt has an unusual one: up to 1,000 points a month for qualifying Peloton workouts and equipment. Marriott Bonvoy members earn Uber and Uber Eats points, including double points on $40-plus food orders delivered to certain extended-stay properties.

The catch is that every partnership has terms — qualifying purchases, minimum spends, or a requirement to give your loyalty number at check-in (Southwest car rental partners, for instance, only pay out if you ask at the time of booking). Most also require you to choose points over the default hotel currency, so read the small print before assuming miles are stacking up automatically.

Why bother? Because these are rewards on money you're already spending. A airport Uber here, a rental car there, a week of coffee runs — it adds up to real miles that can shave hundreds off a future flight or hotel night. If you fly one airline regularly, spend ten minutes linking its partner apps and you'll never look at your coffee receipt the same way again.
