Understanding Airline Alliances and How to Earn Star Alliance Miles on a Different Airline
Before we get tactical about how to earn Star Alliance miles on a different airline, you need to understand what airline alliances actually are and why they exist.
What Is Star Alliance?
Star Alliance is the world’s largest airline alliance with 26 member airlines spanning every continent. It was founded in 1997 by five airlines (United, Lufthansa, Air Canada, SAS, and Thai Airways) who realized that partnering would benefit everyone—airlines get broader networks without buying more planes, and passengers get seamless travel across more destinations.
Today, Star Alliance includes major carriers like United, Lufthansa, Air Canada, Singapore Airlines, ANA, Swiss, Turkish Airlines, and many others. Together, they serve over 1,300 destinations in 195 countries. That’s the power behind knowing how to earn Star Alliance miles on a different airline.
The Other Major Alliances
Star Alliance isn’t alone. There’s also Oneworld (including American Airlines, British Airways, Qantas, Cathay Pacific, Qatar Airways) and SkyTeam (Delta, Air France, KLM, Korean Air). Each alliance operates similarly—you can earn and redeem miles across partner airlines.
For this guide, we’re focusing specifically on how to earn Star Alliance miles on a different airline, but the principles apply to other alliances too.
Why This Matters for Your Travel
Let’s say you’re based in Denver (a United hub) but you’re flying to Bangkok via Singapore Airlines. If you know how to earn Star Alliance miles on a different airline, you can credit your Singapore Airlines flight to your United MileagePlus account. Those miles then count toward United elite status and can be redeemed for future United flights or any Star Alliance partner.
Without this knowledge, you might earn Singapore KrisFlyer miles that are harder to redeem if you rarely fly Singapore Airlines. That’s why understanding how to earn Star Alliance miles on a different airline is game-changing.

How to Earn Star Alliance Miles on a Different Airline: The Mechanics Explained
Now let’s get into the actual process of how to earn Star Alliance miles on a different airline.
Step 1: Choose Your “Home” Frequent Flyer Program
The first decision in how to earn Star Alliance miles on a different airline is picking which Star Alliance program becomes your primary account. This typically depends on:
Your home airport: If you live near a United hub (Denver, Chicago, Houston, Newark, San Francisco), United MileagePlus makes sense. Near a Toronto? Air Canada Aeroplan. Near Washington DC? Consider United or Lufthansa Miles & More since both serve that area well.
Where you want to travel: Some programs are better for specific redemptions. ANA Mileage Club has excellent Star Alliance award availability. Avianca LifeMiles sometimes offers cheaper redemptions to Europe.
Program benefits: United MileagePlus miles never expire. Aeroplan recently revamped with no expiration as well. Turkish Miles&Smiles offers interesting sweet spots for certain routes.
Most people choose the program of their most-flown airline. If you fly United domestically but occasionally take international trips on other Star Alliance carriers, stick with United MileagePlus and credit everything there. That’s the foundation of how to earn Star Alliance miles on a different airline.
Step 2: Book Eligible Fare Classes
Here’s where many travelers mess up when learning how to earn Star Alliance miles on a different airline: not all fares earn miles, and not all fares earn the same amount.
Airlines use fare class codes (single letters like Y, B, M, K, etc.) to determine mileage earning. Generally:
- Full-fare economy (Y, B classes): Earns 100% of miles flown
- Discount economy (M, H, Q, etc.): Earns 50-75% of miles flown
- Deep-discount economy (L, K, etc.): Earns 25-50% of miles flown or sometimes zero
- Basic economy on some carriers: May not earn any miles at all
Premium cabins earn bonuses:
- Premium economy: Usually 100-125% of miles flown
- Business class: Typically 125-150% of miles flown
- First class: Often 150-200% of miles flown
Before booking, check the earning chart of your chosen frequent flyer program for the specific airline you’re flying. United’s website has a chart showing exactly how many miles you’ll earn when flying each Star Alliance partner in each booking class. This is essential knowledge for how to earn Star Alliance miles on a different airline.
Step 3: Add Your Frequent Flyer Number When Booking
When you book a flight on a Star Alliance airline but want to credit it to a different Star Alliance program, add your frequent flyer number during booking or after. This is the actual mechanism of how to earn Star Alliance miles on a different airline.
During booking: Most airline websites have a field for “frequent flyer program” where you select your program and enter your number. Choose your home program (like United MileagePlus) even though you’re flying a different airline (like Lufthansa).
After booking: You can usually add or change your frequent flyer number in “Manage Booking” on the airline’s website or by calling their customer service. Do this before you fly for best results.
At check-in: As a last resort, you can provide your frequent flyer number at airport check-in or the gate. But don’t rely on this—gate agents sometimes make mistakes or the system doesn’t process it correctly.
Step 4: Verify Miles Post-Flight
After your flight, check your frequent flyer account within 3-7 days. Most Star Alliance miles post within 48 hours, but some airlines (I’m looking at you, Air India and South African Airways) can take weeks.
If miles don’t appear within two weeks, file a missing mileage claim through your frequent flyer program’s website. You’ll need your boarding pass and ticket number, so save these documents. This is an important troubleshooting step in how to earn Star Alliance miles on a different airline.
Strategic Approaches to Maximize How to Earn Star Alliance Miles on a Different Airline
Now that you understand the basics of how to earn Star Alliance miles on a different airline, let’s talk strategy.
Focus on Earning Rates, Not Just Flying
Different Star Alliance programs award different amounts for the same flight. A Lufthansa flight from New York to Frankfurt might earn:
- 3,850 miles in United MileagePlus
- 3,850 miles in Lufthansa Miles & More
- 4,300 miles in Air Canada Aeroplan (with a 25% transfer bonus during promotions)
Research which program gives the best earning rate for the routes you fly most. Sometimes it makes sense to credit certain flights to different programs when you’re advanced at how to earn Star Alliance miles on a different airline.
Elite Status Considerations
Here’s where it gets interesting. When figuring out how to earn Star Alliance miles on a different airline for status purposes, miles usually credit as “redeemable miles” but not always as “elite-qualifying miles.”
For United MileagePlus elite status, you need Premier Qualifying Points (PQPs) and Premier Qualifying Flights (PQFs) or miles. Flying on Star Alliance partners earns you miles but typically fewer elite-qualifying credits than flying United metal.
However, some programs are more generous. Turkish Miles&Smiles counts all Star Alliance flights equally toward status. Research your program’s specific rules about how to earn Star Alliance miles on a different airline for elite status purposes.
The “Mattress Run” Strategy
Some savvy travelers book cheap flights on Star Alliance partners specifically for the miles and status credits—these are called “mileage runs” or “mattress runs” (since you might book a flight, check in, and literally sleep at the airport before flying home the same day).
If you’re close to hitting elite status and need a few thousand more miles, a cheap Lufthansa roundtrip from your city to a nearby destination could push you over. That’s advanced knowledge of how to earn Star Alliance miles on a different airline.
Credit Card Partnerships Multiply Earnings
Most Star Alliance airlines have co-branded credit cards that earn bonus miles. The United Quest Card earns 3x miles on United purchases and 2x on all other travel. Use it when booking Star Alliance partner flights and you’ll earn:
- 2x miles from credit card spending
- Flight miles credited to your MileagePlus account
You’re essentially double-dipping when you master how to earn Star Alliance miles on a different airline combined with strategic credit card use.
Book Through the Right Channel
Where you book affects mileage earning. Generally:
- Booking directly with the operating airline: Best for guaranteed mileage crediting
- Booking through a partner airline: Usually fine, but verify your frequent flyer number is in the reservation
- Booking through OTAs (Expedia, Booking.com, etc.): Often works but riskier—the frequent flyer number doesn’t always transfer correctly
For foolproof results with how to earn Star Alliance miles on a different airline, book directly or through your home airline’s website when possible.
Common Mistakes When Learning How to Earn Star Alliance Miles on a Different Airline
Let me save you from painful lessons about how to earn Star Alliance miles on a different airline.
Mistake #1: Booking Basic Economy and Expecting Miles
United Basic Economy, Lufthansa Economy Light, and similar ultra-low fares often don’t earn any miles on partner airlines. You saved $30 on the ticket but lost 3,000+ miles worth $60+ in value. False economy.
When booking, always check if the fare earns miles. Sometimes paying $20-40 more for a regular economy fare dramatically increases what you earn when learning how to earn Star Alliance miles on a different airline.
Mistake #2: Spreading Miles Across Multiple Programs
I see this constantly—travelers have 5,000 miles in United, 3,000 in Lufthansa, 2,000 in Air Canada. That’s 10,000 miles that can’t buy anything because they’re fragmented.
Pick one Star Alliance program and consistently credit everything there. That’s fundamental to how to earn Star Alliance miles on a different airline. The only exception is when you’re strategically using multiple programs for specific redemptions—but that’s advanced travel hacking.
Mistake #3: Forgetting to Add Your Number
You’d be shocked how many people forget to add their frequent flyer number when booking. Then they try to retroactively claim miles weeks later and discover the airline needs boarding passes they threw away.
Make it automatic: as soon as you book any Star Alliance flight, verify your frequent flyer number is in the reservation. This is basic housekeeping for how to earn Star Alliance miles on a different airline.
Mistake #4: Not Understanding Earning Charts
Every frequent flyer program publishes earning charts showing exactly how many miles you’ll earn on each partner in each fare class. These are publicly available on airline websites.
Before committing to one program for how to earn Star Alliance miles on a different airline, compare earning charts. You might find that Singapore KrisFlyer gives you 150% miles on certain Lufthansa business class bookings while United gives you 125%—that difference adds up.
Mistake #5: Ignoring Expiration Policies
United and Air Canada miles don’t expire. Lufthansa Miles & More miles expire after 36 months of inactivity. Turkish Miles&Smiles used to be great but now has expiration rules.
Factor this into your choice of program for how to earn Star Alliance miles on a different airline. There’s no point accumulating 100,000 miles if they’ll expire before you use them.
Advanced Tactics: Maximizing How to Earn Star Alliance Miles on a Different Airline
Once you’ve mastered the basics, these advanced strategies will supercharge your results.
The “Triangle Route” Strategy
Book positioning flights strategically. Instead of flying direct United from Chicago to Frankfurt, fly Chicago to Newark on United, then Newark to Frankfurt on Lufthansa. Both flights earn United miles, but you’ve flown more segments toward status and earned more miles total.
This is geography arbitrage applied to how to earn Star Alliance miles on a different airline.
Promotional Bonuses Stack
Airlines frequently offer bonus promotions: “Earn 2x miles on flights to Europe” or “1,000 bonus miles per round trip on Star Alliance partners.” Register for these before flying.
Some promotions stack, meaning you earn your regular miles PLUS promotional bonuses. Following promotion calendars is part of mastering how to earn Star Alliance miles on a different airline.
Hidden Partners and Codeshares
Sometimes an airline codeshares with a Star Alliance member even though they’re not in the alliance. For instance, you might book a United flight number that’s actually operated by Air Dolomiti (a Lufthansa subsidiary). Understanding these relationships helps with how to earn Star Alliance miles on a different airline.
Always check the “operated by” field when booking. If it’s operated by a Star Alliance carrier (even if the ticket number is different), you can usually earn miles.
Strategic Program Switching
Some advanced travelers maintain two Star Alliance frequent flyer accounts and strategically choose which to credit based on the flight. They might credit short-haul economy flights to Turkish Miles&Smiles (which has good short-haul redemptions) and long-haul business class to United (better transatlantic awards).
This is PhD-level how to earn Star Alliance miles on a different airline, but it’s how people maximize value.
FAQs About How to Earn Star Alliance Miles on a Different Airline
Q1: Can I earn miles on any Star Alliance airline by crediting to my United account? Yes, you can earn miles on any Star Alliance member airline and credit them to your United MileagePlus account. This is the core concept of how to earn Star Alliance miles on a different airline. However, the number of miles earned depends on the fare class and specific earning chart between United and that partner airline.
Q2: Do I need to be a member of multiple Star Alliance programs to earn miles? No, you don’t need accounts with every airline to master how to earn Star Alliance miles on a different airline. You just need one account with your chosen “home” program. You can then credit flights from any Star Alliance partner to that single account. However, some travelers maintain multiple accounts for strategic reasons.
Q3: Can I credit the same flight to two different frequent flyer programs? No, absolutely not. Each flight can only be credited to one frequent flyer account. You must choose which program receives the miles when booking. This is a fundamental rule of how to earn Star Alliance miles on a different airline—pick one program per flight, no double-dipping.
Q4: What if I forgot to add my frequent flyer number before flying? You can usually claim miles retroactively by submitting a missing mileage claim through your frequent flyer program’s website. You’ll need your ticket number and boarding pass as proof. Most programs allow retroactive claims for up to 12 months after the flight, though this varies. Save all boarding passes for this reason when learning how to earn Star Alliance miles on a different airline.
Q5: Do codeshare flights earn the same miles as regular flights? Usually yes, but it depends on the operating carrier. For how to earn Star Alliance miles on a different airline purposes, what matters is which airline actually operates the flight (not whose ticket number or flight number it is). A United flight number operated by Lufthansa earns miles based on Lufthansa’s earning chart when credited to United, not United’s own rates.
Conclusion: Your Star Alliance Miles Strategy Starts Now
Understanding how to earn Star Alliance miles on a different airline opens up a world of possibilities that most travelers never discover. Instead of accumulating small, useless balances across multiple programs, you can strategically funnel all your flying into one powerful account that gets you free flights and upgrades faster.
The key to mastering how to earn Star Alliance miles on a different airline is consistency and awareness. Pick your home program based on where you fly most and where you want to go. Add your frequent flyer number to every single Star Alliance booking. Check earning charts before purchasing tickets to avoid fare classes that earn nothing. Track your miles and file claims when they don’t post correctly.
Within a year of applying these principles, you’ll have accumulated thousands of miles—potentially enough for a free transatlantic flight in economy or a hefty discount on business class. And if you’re strategic about status, you could be enjoying priority boarding, lounge access, and complimentary upgrades across all 26 Star Alliance carriers.
The planes are flying whether you’re earning miles or not. The alliances exist whether you understand them or not. The only question is whether you’ll take advantage of how to earn Star Alliance miles on a different airline or leave thousands of dollars in value on the table.
Start with your next flight. Add that frequent flyer number. Watch those miles stack up. Your future self will thank you when you’re boarding that business class flight to Tokyo using miles instead of cash.
