The smartest way to earn airline miles isn't through special travel purchases—it's through your everyday spending. By using the right credit card for general purchases like online shopping, dining, and department stores, you can earn significant airline miles on the money you already spend daily.
This guide focuses on cards that maximize airline miles rewards across general spending categories using Merchant Category Codes (MCC), helping you earn miles on everyday purchases rather than just travel bookings.
1. UOB Visa Signature - Best Overall for General Spending
Rewards Rate: 4 MPD = 10X UNI$ for a wide variety of expenditures

- Dining (MCC 5812, MCC 5814)
- Travel bookings (MCC 3000-3299, 3351-3500)
Best For: People who want a simple card that earns maximum airline miles on everyday purchases. Perfect for general spending across multiple categories without needing multiple specialized cards.
Key Considerations:
- Capped at $1,000 per month in bonus rewards

Why General Spending Matters for Airline Miles
Many people focus on travel-specific purchases to earn airline miles, but the real opportunity lies in optimizing your everyday spending. The average person spends significantly more on regular purchases—online shopping, dining, groceries, and bills—than on travel bookings. By using cards that earn high miles rates on these general spending categories, you can accumulate airline miles much faster than through travel spending alone.
The strategy is simple: use cards that offer 4 MPD on everyday categories, and let your normal spending fuel your next flight.
