United vs Delta: Which Airline Program Is Better?

By Bryce Casson, Founder · Cardocrat · Updated June 2026
The short answer: United generally offers better award value and a broader Star Alliance partner network, while Delta wins on operational reliability and domestic experience but charges more miles for awards. For maximizing miles, United edges it; for service and a strong domestic network, Delta appeals.

Award value and partners

United MileagePlus uses dynamic pricing but generally prices awards more reasonably than Delta, and as a Star Alliance member it has a huge partner network for international redemptions, plus the useful Excursionist Perk (a free segment on some round-the-world style awards) and no close-in booking fees. See United cards.

Where Delta wins

Delta SkyMiles is known for high award prices (miles often stretch less, which is why people grumble about their value), but Delta counters with strong operational reliability, a polished domestic experience, and a robust SkyTeam network. Delta miles never expire and awards have no close-in fees. See Delta cards.

The verdict

If your priority is getting the most from miles, United generally gives more value and broader partners. If you value reliability, route network from a Delta hub, and service, Delta is worth the richer mileage prices. Both earn via co-branded cards and transferable points (Delta from Amex; United from Chase), so where you live and fly often decides it. See best airline program.
