Mistake #1: Carrying a Balance
This is the #1 mistake that destroys all travel hacking value. If you carry a balance and pay 20-25% APR interest, you lose money even with the best rewards.
Example: You earn 75,000 Chase points ($750-1,500 value) but carry a $5,000 balance for 6 months at 22% APR. Interest cost: $550. Your net gain: $200-950, but you're paying unnecessary interest.
Rule: If you can't pay your statement balance in full every month, don't open new credit cards. Focus on paying down debt first.
Mistake #2: Letting Points Expire
Most airline and hotel points expire after 18-24 months of inactivity. Per program terms, you must earn or redeem at least one point to reset the expiration clock.
Expiration Policies
- Chase Ultimate Rewards: Don't expire as long as your card is open
- Amex Membership Rewards: Don't expire as long as you have an Amex card that earns points
- United MileagePlus: Expire after 18 months of inactivity
- Delta SkyMiles: Don't expire (as of 2020 policy change)
- Southwest Rapid Rewards: Expire after 24 months of inactivity
- Hyatt points: Expire after 24 months of inactivity
- Marriott Bonvoy: Expire after 24 months of inactivity
How to prevent expiration:
- Use a shopping or dining portal to earn 1-5 points
- Book a cheap award (even 5,000-point hotel stay resets the clock)
- Transfer points from a credit card program
- Make a purchase with a co-brand credit card
Mistake #3: Applying for Chase Cards Over 5/24
Chase auto-denies if you've opened 5+ personal cards in the past 24 months. Applying when you're over 5/24 wastes a hard pull and delays your next application by 30 days.
Check your 5/24 status before applying: Count all personal credit cards opened in the past 24 months (from any bank). Business cards don't count (except Capital One). Authorized user cards might count (but can be removed).
Mistake #4: Transferring Points Before Confirming Award Space
Always search for award availability before transferring points. Award space can disappear in minutes. If you transfer 50,000 Chase points to United and the award sells out, those points are stuck as United miles forever.
Correct order:
- Search for award availability on airline website
- Find the exact flight you want
- Transfer points (Chase transfers are instant)
- Book immediately after transfer posts
Mistake #5: Redeeming Points at Low Value
Never redeem flexible points below their baseline value. Chase Ultimate Rewards have a 1.25¢/point baseline (Sapphire Preferred portal). Redeeming for 0.8¢/point is wasting 36% of your value.
Example bad redemption: Using 50,000 Chase points for a $400 domestic flight = 0.8¢/point. Portal price for same flight: 32,000 points at 1.25¢/point. You wasted 18,000 points.
Use our CPP calculator to check redemption value before booking.
Mistake #6: Not Using Shopping Portals
Forgetting to click through shopping portals costs 2-10x extra points on every online purchase. A $500 purchase could earn 500-5,000 extra points depending on the retailer and portal.
Solution: Before buying online, check Chase Shopping, Rakuten, or airline shopping portals. Clicking through takes 10 seconds and earns thousands of points per year.
Mistake #7: Overspending to Hit Minimum Spend
Don't buy things you don't need just to earn a welcome bonus. Spending $1,000 on unnecessary purchases to earn a $750 bonus is a net loss of $250.
Only apply for cards when you have natural spending coming up: rent, utilities, large planned purchase, upcoming travel. If you can't naturally meet the minimum spend, wait to apply.
Mistake #8: Closing Cards Too Early
Closing cards within the first 12 months can get you blacklisted by the issuer. Chase, Amex, and other banks track account closures. Close too many cards too fast and they'll deny future applications.
Rule: Keep cards open for at least 12 months. Downgrade to no-annual-fee versions instead of closing if you don't want to pay the fee.
Mistake #9: Not Tracking 5/24 Status
Losing track of your 5/24 status leads to wasted Chase applications. Keep a spreadsheet with every card opened, the open date, and when it drops off your 5/24 count (24 months later).
See Lesson 19 for tracking templates.
Mistake #10: Booking Through Third Parties
Booking hotels or flights through Expedia, Priceline, or Booking.com means you don't earn loyalty points and can't use elite benefits. Always book directly with the airline or hotel to earn points and status credits.
Exception: Using Chase or Capital One portals is fine because you're redeeming your own points. But don't book with third-party sites using cash.
Mistake #11: Ignoring Bonus Categories
Using the wrong card for purchases costs 2-4x earning potential. Paying for groceries with a 1x card when you have an Amex Gold (4x groceries) wastes 3x points on every purchase.
Solution: Carry 2-3 cards and use the right one for each category:
- Groceries/dining: Amex Gold (4x)
- Travel: Chase Sapphire Preferred (2x) or Amex Platinum (5x flights)
- Everything else: Chase Freedom Unlimited (1.5x) or Capital One Venture (2x)
Mistake #12: Not Planning Redemptions
Earning 500,000 points with no travel plan means points sit unused and lose value to devaluations. Have a general redemption goal before opening cards.
Strategy: Pick 1-2 dream trips (see Lesson 3), calculate points needed, then apply for cards to reach that goal. Use points within 1-2 years.
Mistake #13: Missing Minimum Spend Deadlines
Missing the 3-month minimum spend window forfeits the entire welcome bonus. If you need to spend $4,000 in 3 months and only spend $3,800, you get zero bonus points.
Prevention: Track spend weekly in a spreadsheet. Set a reminder 7 days before the deadline. Only apply when you're confident you can meet spend naturally.
Mistake #14: Applying Too Fast (Velocity)
Opening 3 cards in one month triggers velocity denials. Issuers see rapid applications as risky behavior and auto-deny even if you meet all published requirements.
Safe pace: 1 card every 3-6 months per issuer. Space applications even if you're excited about a new bonus. Patience prevents denials.
Mistake #15: Not Reading Terms
Every card has bonus eligibility rules. Chase Sapphire family cards have a 48-month restriction: you can't earn a Sapphire bonus if you've received one in the past 48 months. Applying without reading terms wastes a hard pull.
Always check:
- Bonus eligibility rules (24-month, 48-month, lifetime restrictions)
- Minimum spend amount and deadline
- Annual fee and when it posts
- Cancellation/downgrade restrictions
How to Avoid These Mistakes
- Set up autopay to pay full balance every month
- Track your 5/24 status in a spreadsheet
- Search award space before transferring points
- Calculate CPP before redeeming points
- Use shopping portals for online purchases
- Keep cards open 12+ months before closing/downgrading
- Space applications 3-6 months apart
- Read all terms before applying
