# Delta SkyMiles vs United MileagePlus 2026: Which Loyalty Program Wins?
By Daniel Rozin | A Versus B | July 4, 2027
Airline loyalty programs are worth real money if you pick the right one and use it strategically. Delta SkyMiles and United MileagePlus are the two most-compared programs among US airline travelers — both have a large footprint, competitive status tiers, and extensive redemption options. The differences between them determine which one actually benefits you.

Status Tier Comparison#
Delta SkyMiles Medallion Status#
| Tier | Qualification (MQM + Spend) | Benefits |
|---|---|---|
| Silver Medallion | 25,000 MQM + $3,000 spend | Priority boarding, waived fees, upgrade eligibility |
| Gold Medallion | 50,000 MQM + $8,000 spend | Same-day upgrade, 2 complimentary upgrades/yr |
| Platinum Medallion | 75,000 MQM + $10,000 spend | Complimentary upgrades, Delta Sky Club passes |
| Diamond Medallion | 125,000 MQM + $15,000 spend | 4 Sky Club passes, top upgrade priority |
MQM = Medallion Qualifying Miles. Both flight miles and spending count toward status.
United MileagePlus Premier Status#
| Tier | Qualification (PQP + Segments) | Benefits |
|---|---|---|
| Premier Silver | 4,000 PQP + 30 segments | Priority boarding, two checked bags |
| Premier Gold | 8,000 PQP + 60 segments | Complimentary Economy Plus, upgrade eligibility |
| Premier Platinum | 12,000 PQP + 90 segments | Complimentary upgrade priority on select fares |
| Premier 1K | 18,000 PQP + 120 segments | Top upgrade priority, United Club passes, 1K Desk |
PQP = Premier Qualifying Points, earned at 1 PQP per dollar spent on United purchases.
Key difference in qualification: United moved to dollar-based qualification (Premier Qualifying Points = dollars spent), which makes status qualification more predictable for business travelers. Delta uses a hybrid MQM (miles flown) + spending model.

Earning Miles: How Fast Do Miles Accumulate?#
Earning on Flights#
Both programs award miles based on dollars spent, not miles flown (the industry-standard post-2015 shift):
| Program | Base Earn Rate | Silver Status | Gold/Platinum | Top Status |
|---|---|---|---|---|
| Delta SkyMiles | 5 miles/$1 | 7 miles/$1 | 8-9 miles/$1 | 11 miles/$1 |
| United MileagePlus | 5 miles/$1 | 7 miles/$1 | 8-10 miles/$1 | 11 miles/$1 |
Earn rates are similar. The main difference is in partner earning and redemption value.
Credit Card Partners#
| Program | Primary Cobranded Cards | Typical Intro Offer | Earn on General Spend |
|---|---|---|---|
| Delta SkyMiles | American Express Delta cards | 60,000-100,000 miles | 1-2 miles/$1 |
| United MileagePlus | Chase United cards | 60,000-80,000 miles | 1-2 miles/$1 |
Both have strong cobranded card ecosystems. Chase's Ultimate Rewards points transfer to MileagePlus at 1:1, giving United miles a significant acquisition advantage — Chase Sapphire Preferred ($95/yr) earns 3x on dining, 2x on travel, all transferable to United. Delta requires the Amex Delta cards for cobranded earning.
The Chase advantage for United: If you hold Chase Sapphire Reserve or Preferred, your Chase points are transfer-flexible to United (among 10+ airline partners). This makes earning United miles through everyday spend more accessible.

Redemption: Where the Real Difference Lives#
This is where MileagePlus and SkyMiles diverge most significantly.
Delta SkyMiles: Dynamic Pricing#
Delta eliminated its award chart in 2023. All redemptions use dynamic pricing — the miles required vary based on cash fare prices, demand, and availability.
What this means:
- Off-peak flights can be excellent value (domestic one-way in coach: 8,000-15,000 miles)
- Peak demand flights can be poor value (same route: 40,000-60,000 miles)
- Business class and international redemptions are increasingly variable
- There is no fixed award chart to plan against — you must search and compare each specific date
SkyMiles' best use cases:
- Off-peak domestic coach travel
- Last-minute upgrades when upgrade miles are offered
- Delta Vacations packages (cash + miles combinations)
SkyMiles weakness: International premium cabin redemptions have become expensive and unpredictable. Delta's long-haul partner awards (via SkyTeam) often require more miles than MileagePlus partner awards for comparable routes.
United MileagePlus: Partner Award Flexibility#
MileagePlus is a member of Star Alliance — the world's largest airline network. This gives United's miles access to partner airlines with genuinely valuable redemptions:
| Route | Airline | Miles Required | Cash Equivalent |
|---|---|---|---|
| US–Tokyo (Business) | ANA | 88,000 one-way | $4,000-8,000 |
| US–Singapore (Business) | Singapore Airlines | 88,000 one-way | $4,000-7,000 |
| US–Frankfurt (Business) | Lufthansa | 70,000 one-way | $3,000-6,000 |
| US–Johannesburg (Business) | South African Airways/Lufthansa | 100,000 one-way | $4,000-8,000 |
| Domestic (Coach) | United | 12,500-25,000 one-way | $150-400 |
Star Alliance partner awards on ANA and Singapore Airlines via MileagePlus are among the highest-value redemptions in airline loyalty programs. ANA Business Class from the US West Coast to Japan at 88,000 miles round-trip can be worth $6,000-14,000 in equivalent cash value.
MileagePlus's weakness: United's own domestic award pricing is less competitive than SkyMiles for off-peak domestic flights. The real value is in partner redemptions.

Lounge Access#
Delta Sky Club#
- Day passes: $50/day (cash)
- Complimentary access: Platinum Medallion and above; Delta Amex Reserve cardholders
- Locations: Major Delta hubs (ATL, MSP, JFK, SEA, LAX, BOS, DTW, SLC)
- Quality: Generally excellent; varied food selection, comfortable seating, shower suites
United Club#
- Day passes: $59/day
- Complimentary access: Premier 1K (top tier); United Club Chase card
- Locations: United hubs (ORD, EWR, IAH, DEN, SFO, LAX, IAD)
- Quality: Solid; recent renovations at major hubs; inconsistent at smaller locations
Delta Sky Club is generally rated higher than United Club in traveler surveys for amenity quality and food.

The Upgrade Game#
Delta Upgrades#
Delta offers complimentary upgrades starting at Platinum Medallion (75,000 MQM). Gold Medallion receives 2 complimentary upgrade certificates per year.
Delta's upgrade system is complex: Medallion Upgrade Certificates (MUC) can be applied to specific flights, and complimentary upgrades clear based on availability and status.
United Upgrades#
United's upgrade system has been simplified: Premier Gold and above are eligible for complimentary upgrades on standard economy fares. Upgrade availability and clearing order is prioritized by status level.
Practical reality: Neither program offers reliable upgrades on busy routes or peak times at mid-status tiers. Top status (Diamond/1K) is required for consistent upgrade access.

Who Should Choose Each Program#
Choose Delta SkyMiles if:
- You fly primarily domestically in the US
- You live near a Delta hub (Atlanta, Minneapolis, Seattle, Detroit, Salt Lake City, NYC)
- You want reliable domestic off-peak redemptions
- You prefer the Delta travel experience
Choose United MileagePlus if:
- You fly internationally to Asia, Europe, or beyond
- You use Chase credit cards (Sapphire Preferred/Reserve) — direct 1:1 transfer to MileagePlus
- You want flexibility to book ANA, Singapore Airlines, or Lufthansa business class at partner rates
- You live near a United hub (Chicago, Houston, Newark, Denver, San Francisco)

The Verdict#
For domestic travel: Delta SkyMiles — better off-peak domestic redemptions, superior airline reliability and customer service, and excellent Sky Club access for upper-tier Medallion members.
For international premium travel: United MileagePlus — Star Alliance partner awards on ANA and Singapore Airlines are among the best redemptions in loyalty programs. MileagePlus miles earned via Chase Sapphire cards are among the most transferable points in the industry.
For most travelers: The choice should follow the airline, not the program. Fly Delta from Delta hubs, earn SkyMiles. Fly United from United hubs, earn MileagePlus. Status benefits compound on the airline you actually use.
