The average value of United MileagePlus miles in 2025 is approximately 1.2 to 1.4 cents per mile (CPM) based on real-world redemptions. This valuation is consistent with historical trends but shows a slight compression due to award chart volatility and reduced saver-level inventory.
United eliminated its fixed award chart in favor of dynamic pricing, which means mile values now vary based on demand, destination, and booking time. However, partner airline awards, booked through United’s Star Alliance partners like ANA or Lufthansa, still follow more predictable pricing and offer higher redemption values, often exceeding 2.0 CPM for business class itineraries.
United Miles Value by Redemption Type in 2025
| Redemption Type | Average CPM Value | Notes |
| Domestic Economy | 0.9 – 1.1 CPM | Low value, especially with dynamic pricing |
| Domestic Business | 1.2 – 1.4 CPM | Better, but limited availability |
| International Economy | 1.3 – 1.5 CPM | Decent if booked early |
| International Business/First | 1.8 – 2.6 CPM | High-value redemptions via partners (e.g. ANA, SWISS) |
| Star Alliance Partner Awards | 2.0 – 3.0+ CPM | Best option for maximizing value |
Expert note: Travelers aiming for premium cabins on long-haul international routes extract the most value, particularly on partner airlines.
When Does It Make Sense to Buy United Miles in 2025?
Buying United miles makes sense only when the cost per mile is lower than the redemption value you expect to achieve. In 2025, the base cost to buy United miles without a promotion is 3.5 cents per mile, which is well above the average redemption value. However, this changes during promotional events.
Buying miles can be smart if:
- You’re topping up your balance to secure an award flight
- You need to book a last-minute premium cabin flight, and the cash fare is very high
- There’s a bonus sale offering at least 80%+, bringing effective CPM below 1.9
Example: Business Class Redemption vs Cash Fare
- SFO to Tokyo (ANA Business Class)
- Miles required: 88,000
- Cost to buy: $1,650 with 100% bonus (1.87 CPM)
- Cash fare: $4,800
- Value: 5.45 CPM → Excellent value
Bottom line: Buy miles only when you’ve identified a high-value redemption, not speculatively.

What Are the Hidden Perks of Buying United Miles?
Beyond just redemption, United miles come with operational and strategic advantages that aren’t always visible to casual flyers.
Hidden Perks
- Access to Star Alliance inventory: United.com often displays partner awards that aren’t visible elsewhere
- No close-in booking fees: Unlike American Airlines, United doesn’t charge fees for last-minute award bookings
- Award holds: United occasionally allows award holds while miles are transferred or purchased
- Customer-friendly change policy: Post-pandemic, United continues to waive many change and cancellation fees
These elements make United miles more flexible and usable, especially in dynamic planning scenarios.
What Are the Risks and Limitations of Buying United Miles?
While strategic buying can yield excellent value, the risks must be clearly understood.
Main Risks in 2025
- No refunds: Purchased miles are final; no returns or exchanges
- Devaluation risk: United has shown a pattern of stealth devaluations without notice
- Dynamic pricing: Saver awards are becoming rarer
- Award availability: Premium partner awards require planning and may not always be available
- Expiration: Miles expire after 18 months of inactivity (can be extended through activity)
Comparison With Transferable Points
Programs like Chase Ultimate Rewards transfer to United 1:1 and offer greater flexibility, making mile purchases a less optimal strategy for most travelers unless an urgent booking is required.
How Do United Miles Compare to Other Airline Loyalty Programs in 2025?
MileagePlus remains competitive in its global reach, but falls short on domestic redemptions when compared to Delta and American.
United vs Competitors: 2025 Comparison
| Feature | United MileagePlus | Delta SkyMiles | American AAdvantage |
| Award Chart | None (dynamic) | Dynamic pricing | Hybrid |
| Average CPM | 1.2 – 1.4 | 1.1 – 1.3 | 1.3 – 1.6 |
| Close-In Booking Fees | None | None | Yes |
| Partner Network | Star Alliance (26+) | SkyTeam | oneworld |
| Premium Award Availability | Good (partners) | Poor | Decent |
| Change/Cancellation Fees | Low | High (basic fares) | Moderate |
Expert takeaway: United offers the best global partner redemptions, but less value in domestic travel compared to AA’s MileSAAver options or Delta’s flash sales.

Should You Buy or Earn United Miles in 2025?
Buying miles remains less efficient than earning through flights or credit cards, except in limited use cases.

| Buying (with 100% bonus) | 1.75 CPM | Best-case scenario |
| Flying (paid ticket) | Varies (low) | Earn PQPs and status benefits |
| Credit Card Spend | As low as 0.7 CPM | Chase United cards offer multipliers |
| Transferring from Chase | Free (points earned) | Flexible and instant |
Verdict: If flexibility is important and time allows, earning or transferring miles is better than purchasing outright.
