Frequent flyers often mix airlines within global alliances, expecting their loyalty benefits to follow them seamlessly. A common question among travelers planning international or transcontinental trips is whether United MileagePlus miles can be earned when flying with partner airlines such as Lufthansa or Air Canada. The short answer is yes—but the rules matter more than most travelers realize.
This article breaks down exactly how earning United miles works on Lufthansa and Air Canada flights, what affects mileage credit, how elite benefits apply, and how to avoid common mistakes that cause miles to be lost. Drawing on airline alliance structures, fare class logic, and real-world traveler experiences, this guide provides practical, experience-based clarity rather than surface-level answers.
United Airlines is a founding member of the Star Alliance, which allows passengers to earn and redeem miles across partner airlines. Lufthansa and Air Canada are also core Star Alliance members, making mileage earning possible under defined conditions.
Star Alliance operates under shared loyalty principles, but each airline controls how miles are awarded within its own program. When you credit a Lufthansa or Air Canada flight to United MileagePlus, United—not the operating airline—determines how many miles you receive.
Mileage earnings are influenced by:
Operating airline
Ticketing airline
Fare class purchased
Distance flown or ticket price
MileagePlus elite status
The most important rule to remember is that not all fares earn miles equally, and some discounted fares earn reduced miles or none at all.
United uses a revenue-based system for its own flights but switches to a distance-and-fare-class system for most partner flights. This distinction often surprises travelers expecting consistent mileage returns.
Lufthansa is one of United’s most significant long-haul partners, especially for Europe-bound travel. Earning United miles on Lufthansa flights is straightforward when booked correctly.
You can earn United miles on Lufthansa flights when:
The flight is operated by Lufthansa
The ticket is eligible under United’s partner earning chart
Your MileagePlus number is added before travel
Miles are generally awarded based on distance flown multiplied by a percentage tied to fare class.
Not all Lufthansa tickets earn the same mileage. Below is a simplified comparison:

Many travelers lose miles due to:
Booking deeply discounted promotional fares
Forgetting to add their MileagePlus number
Assuming all Star Alliance flights earn miles equally
If a fare earns zero miles, United will not retroactively credit it.
Air Canada operates under a slightly different model but remains highly compatible with United MileagePlus earning rules.
You can earn United miles on Air Canada flights when:
The flight is operated by Air Canada
The fare class qualifies for MileagePlus earning
The MileagePlus number is attached at booking or check-in
Unlike Lufthansa, Air Canada fares tend to offer broader eligibility, though earning rates still vary.

Basic Economy fares on Air Canada typically:
Earn no United miles
Do not qualify for Premier benefits
Cannot be upgraded using United instruments
Travelers focused on mileage accumulation should avoid these fares.
Mileage earning is not just about the airline you fly—it’s about how the ticket is structured.
A flight operated by Lufthansa but ticketed by United may earn miles differently
United-issued tickets sometimes earn miles based on price instead of distance
Always check the operating airline code and fare class before booking.
When United issues the ticket:
Mileage may be calculated using fare price
Some partner flights earn fewer miles than expected
This is especially relevant for multi-city itineraries.
Elite status with United can enhance partner flight experiences but does not override mileage earning rules.
Premier members may receive:
Priority check-in
Extra baggage allowance
Priority boarding
Lounge access on international itineraries
However, elite bonuses on mileage earnings are not always applied on partner flights.
United Premier bonuses apply fully on United flights
Partner flights may earn base miles only
Bonus miles depend on fare class eligibility
Based on publicly available information, there is no confirmed data on elite bonus consistency across all partner fares.
Following a simple checklist can prevent lost miles.
Verify fare class eligibility
Avoid Basic or ultra-discounted fares
Compare United-ticketed vs partner-ticketed options
Enter your MileagePlus number correctly
Save booking confirmation screenshots
Confirm fare class on the receipt
Wait up to 14 days for miles to post
Keep boarding passes
File a mileage request if needed
United generally allows mileage credit requests within a defined post-travel window.
