Why MileagePlus Matters
United MileagePlus is the gateway to Star Alliance — 26 airlines including Lufthansa, ANA, Singapore Airlines, Swiss, Austrian, Air Canada, and others. Earning MileagePlus miles from Chase Ultimate Rewards (which transfers 1:1) and using them to book award seats on partner carriers is one of the most reliable paths to high-value international business class travel.
United's partner awards are priced using a distance-based chart for most partners — not dynamically. This means the prices are predictable and occasionally significantly lower than booking directly with the operating carrier.
Earning MileagePlus Miles Without Flying
Chase Ultimate Rewards transfer (1:1): The primary earning method for most points travelers. Cards that earn Chase UR: Sapphire Reserve (3x travel + dining), Sapphire Preferred (2x travel), Freedom Unlimited (1.5x everything), Freedom Flex (5x quarterly categories). Transfer to United at 1:1 instantly.
United co-branded cards (Chase): United Explorer ($95/yr, 2x United, dining, hotels), United Quest ($250/yr, 3x United + 2x select categories), United Club Infinite ($525/yr, 4x United + Club lounge access). Co-branded cards also earn PQPs (premier qualifying points) toward United elite status.
Shopping portal: United's MileagePlus Shopping portal awards miles for purchases at hundreds of retailers — Amazon, Best Buy, Gap, and others. Even small purchases keep your account active (18-month expiration rule).
Dining: United MileagePlus Dining awards miles for restaurant visits on a linked credit card — any card, not just United cards.
Best MileagePlus Partner Award Sweet Spots
ANA Business Class (US→Japan): 80,000 miles round-trip
One of the most consistently praised premium cabin products. United's 80,000-mile round-trip pricing for North America→Japan on ANA delivers exceptional value when ANA business class retails for $5,000–$8,000. That's 6–10 CPP on a round-trip.
Lufthansa Business Class (US→Europe): 70,000 miles round-trip
Lufthansa releases partner award space to United — but only close-in (typically within 2 weeks of departure for economy; business can be 3–6 months out occasionally). Booking Lufthansa business through United avoids the heavy fuel surcharges Lufthansa charges its own members. United doesn't pass through fuel surcharges on Lufthansa awards.
Singapore Airlines Business Class (US→Southeast Asia): ~80,000–100,000 miles
Singapore's regional and longhaul business class are consistently ranked among the best in the world. MileagePlus occasionally has availability on Singapore metal, particularly on regional Southeast Asia routes.
Short-haul partner awards in Europe: Intra-Europe business class on Lufthansa, Austrian, Swiss at 30,000–40,000 miles round-trip. Cash prices for intra-Europe business can be $400–$600, making CPP modest — but useful for positioning flights in a longer itinerary.
Saver vs. Everyday Awards
United uses a two-tier system: Saver awards (lower mileage, limited inventory) and Everyday awards (more availability, significantly more miles). Always search for and book Saver availability. Everyday awards frequently cost 2–3x more miles for the same seat — the extra miles are almost never worth it versus keeping them for a better Saver opportunity.
Close-In Award Booking
United adds a $75 close-in booking fee for awards booked within 21 days of departure. If you're planning an award trip, book more than 21 days out to avoid this fee. The fee applies to United metal — partner awards may not incur the fee (verify at booking).
The 18-Month Inactivity Window
MileagePlus miles expire after 18 months of account inactivity. Any earning activity resets the clock — shopping portal purchases, dining program, hotel stay, or earning from a credit card. Set a calendar reminder 15 months after your last activity to trigger a small earning event if you haven't naturally earned miles. The shopping portal makes this trivial — a $5 purchase at a partner retailer resets 18 months.
MileagePlus vs. Aeroplan for Star Alliance Awards
Both United and Aeroplan access most Star Alliance partners at competitive prices. Key differentiators:
- Aeroplan has no fuel surcharges on most partners — United does on some carriers. For Lufthansa awards, United waives surcharges; for others, verify before booking.
- United has better access to ANA space — their long-standing bilateral partnership provides more inventory than Aeroplan typically shows
- Aeroplan has more flexible routing rules — stopovers and open-jaws are allowed, letting you visit an extra city for free
- United has closer-in awards on its own metal — domestic US on United frequently releases last-minute saver space
For most international premium cabin bookings, having miles in both programs gives you more options than either alone.
