How to Earn 100,000 Miles in 90 Days: The Sign-Up Bonus Strategy
Why Sign-Up Bonuses Are the Fastest Way to Earn Miles
Organic spending earns 1–3 points per dollar. A typical household spends $30,000–$50,000 per year, generating 30,000–150,000 points from spending alone. But a single sign-up bonus can deliver 50,000–100,000 points in 3 months — equivalent to 1–3 years of organic earnings.
The Stacked Bonus Strategy
The most effective approach: open 1–2 new cards per year, meet the minimum spend requirement on each, and collect the bonuses systematically.
| Card | Bonus | Min. Spend | Timeframe | Approx. Value |
|---|---|---|---|---|
| Chase Sapphire Preferred | 60,000 pts | $4,000 | 3 months | $750–$1,200 |
| Amex Gold | 60,000 pts | $6,000 | 6 months | $900–$1,200 |
| Capital One Venture X | 75,000 miles | $4,000 | 3 months | $750–$1,275 |
Meeting Minimum Spend Without Overspending
The #1 mistake: spending extra money “to hit the bonus.” You must spend money you were already going to spend. Smart strategies:
- Pre-pay bills: Car insurance, annual subscriptions, even property taxes (if no fee)
- Buy gift cards at face value: For Amazon, gas stations, or grocery stores you use regularly
- Pay rent via Plastiq: Charges a small fee (2.9%) but earns points — only worthwhile if points value exceeds the fee
- Time big purchases: New appliance, home improvement project, or computer planned anyway? Apply for the card first
Does Opening Multiple Cards Hurt Your Credit?
Short-term: each application drops your score 5–10 points from a hard inquiry. Long-term: opening new cards increases your total available credit, which lowers your utilization ratio and can improve your score. The net impact of 1–2 new cards per year is typically neutral to mildly positive for people with good credit.
Key rule: never apply for new cards within 6 months of applying for a mortgage or auto loan, when your credit score matters most.
The “Cooling Off” Calendar
Chase enforces the 5/24 rule: if you’ve opened 5+ credit cards (any issuer) in the last 24 months, Chase will deny most applications. This is the most important rule in the miles game:
- Apply for Chase cards first (before you have too many new accounts)
- Then move to Amex and Capital One (more lenient policies)
- Wait at least 3 months between applications to let scores recover
Year 1 plan: Chase Sapphire Preferred (60k pts) + Chase Freedom Unlimited (no annual fee, $200 bonus) = 80,000+ points worth $1,000–$1,600 in flights — for spending you were going to do anyway. See the full miles card comparison →
Frequently Asked Questions
What is the Chase 5/24 rule?
Chase will deny most of its credit card applications if you’ve opened 5 or more credit cards from any bank in the past 24 months. This is Chase’s way of limiting bonus-chasing activity. Start with Chase cards before accumulating accounts elsewhere.
