Use Airline Miles Credit Cards for Free Flights

The Problem

You pay full price for every flight and earn nothing on daily spending.

The Hack

Get an airline credit card with a sign-up bonus (typically 50,000-75,000 miles after spending $3,000-4,000 in 3 months). Use for daily spending. Redeem miles for flights.

Why It Works

Sign-up bonuses often equal $500-1,000 in flight value. Ongoing spending earns 1-3 miles per dollar. A family spending $30,000/year on cards earns 1-2+ free domestic round trips annually.

Pro Tips

• Chase Sapphire, Capital One Venture, and Amex Gold are top options
• Sign-up bonus: 50,000-75,000 points = 1-2 domestic round trips
• Pay the balance in full monthly — interest destroys all rewards
• Transfer points to airline partners for maximum value
