United vs. American vs. Delta Miles: Where Do You Actually Win?

Choosing between United, American, and Delta miles isn’t just about who flies out of your home airport. Each program’s points are worth different amounts depending on partners, routes, and restrictions. With airline award charts constantly changing, knowing the quirks helps you squeeze more trips out of your hard-earned points.

Where Each Program Shines for the Right Flyer

001

United: Alliance Access

Unbeatable route map with Star Alliance partners, including access to Swiss, Lufthansa, ANA, and more—especially for international redemptions.

002

American: Premium Cabin Sweet Spot

Flagship premium partners (Qatar, JAL) have business class seats at still-reasonable rates if you can find them, especially on Asia routes.

003

Delta: Everyday Flexibility

Redemptions are easy for most flights, and flash sales can deliver exceptional value, especially on domestic and Caribbean routes.

How to Compare and Choose Your Main Miles Program

Break down decision-making with this step-by-step approach.

01

Assess Your Travel Patterns

Evaluate which airlines and alliances dominate your home airport.

Consider non-stop options, partner carriers, and frequency of international versus domestic flying.

02

Evaluate Award Value and Flexibility

Compare how many miles typical routes cost and the flexibility of redemptions.

Check sample bookings on each site for your usual destinations, and note close-in fees or redemption hurdles.

03

Consider Credit Card Transferability

Determine which programs partner with your main credit card points (Amex, Chase, Citi, Capital One).

United partners with Chase, Delta with Amex, and American mainly with Citi—but transfer policies differ widely.
