Airline miles can seem mysterious, like a secret currency only seasoned travelers or credit card users know how to access. The truth is, you don’t need a premium credit card or huge budget to start earning miles.
With a bit of strategy, anyone can accumulate airline miles without spending extra money, and eventually use them to score free flights, upgrades, or perks.
In this guide, we’ll explore the best free ways to earn airline miles and how to maximize them.
1. Join Airline Loyalty Programs
The first and most important step is joining frequent flyer programs. Every major airline has a loyalty program, and membership is free.
How It Works:
-
Sign up online with your name and email
-
Receive a frequent flyer number
-
Enter it every time you book a flight
Even a single domestic flight earns you miles. Over time, these small amounts add up.
Example: Flying 500 miles domestically might earn you 500 miles in some programs.
2. Fly With Partner Airlines
Most airlines are part of alliances (Star Alliance, Oneworld, SkyTeam). Even if you don’t fly your main airline, you can earn miles by flying partners.
How It Works:
-
Book flights with a partner airline
-
Add your primary airline frequent flyer number
-
Miles accumulate in your main account
Pro Tip: Check which airlines are partners before booking to maximize miles earned.
3. Shop Through Airline Portals
Airline shopping portals are one of the easiest free ways to earn miles without extra spending.
How It Works:
-
Visit the airline’s online shopping portal
-
Click through to retailers like Amazon, Walmart, Macy’s, or Expedia
-
Earn miles for every dollar spent
Example:
-
$50 purchase at a partner store = 500 airline miles
-
No extra money spent—you’re just buying what you were already buying online
4. Participate in Airline Dining Programs
Many airlines offer dining reward programs. You earn miles every time you eat at participating restaurants, cafés, or bars.
How It Works:
-
Register your debit or prepaid card with the program
-
Dine at a participating restaurant
-
Miles automatically post to your account
Pro Tip: Use these programs for your regular dining, no extra spending required.
5. Take Advantage of Promotions and Bonuses
Airlines regularly run promotional campaigns that reward extra miles.
Types of Promotions:
-
Book flights within a certain window
-
Fly specific routes
-
Complete surveys or participate in special events
How to Stay Informed:
-
Subscribe to airline newsletters
-
Follow airlines on social media
-
Monitor frequent flyer forums
Example:
-
Delta sometimes offers double miles for flights to Europe during off-peak months.
6. Use Surveys, Contests, and Online Activities
Some airlines partner with platforms that let you earn miles by completing surveys or small tasks online.
How It Works:
-
Register with airline-affiliated survey sites
-
Complete surveys, quizzes, or watch short videos
-
Earn miles in your account
While not huge amounts, this is completely free and adds up over time.
7. Refer Friends or Family
Many loyalty programs offer bonus miles for referrals.
How It Works:
-
Send your referral link to friends or family
-
When they sign up or complete a flight, you earn bonus miles
Some programs offer 1,000–5,000 miles per referral, which can quickly add up.
8. Earn Miles Through Everyday Purchases (No Credit Card Required)
Even without a credit card, you can still earn miles through:
-
Airline grocery or fuel programs
-
Purchasing gift cards via airline portals
-
Participating in airline surveys or promotions
Pro Tip: Track what you already spend monthly and see how you can route purchases through airline programs.
9. Keep Your Miles Active
Some travelers earn miles but lose them due to expiration.
How to Keep Miles Alive:
-
Fly occasionally with the airline
-
Make small purchases via shopping portals
-
Participate in dining programs
-
Transfer points or use partner activities
Even 1–2 miles per month can reset your expiration clock.
