Taipei to Europe business class in peak season regularly costs NT$150,000 to NT$200,000. Readers I’ve helped redeem miles for the same flight, same flat-bed seat, have paid under NT$50,000. The difference isn’t “saving a bit” — it’s “a whole additional Southeast Asia trip budget.” This is the most complete 2025 beginner’s miles guide: how to earn from zero, how to redeem smartly, and how to lie flat to Europe on what you’d otherwise spend on economy.

The Core of Miles: Why Miles Beat Cash Rebates for Big Trips
Most people think of miles as a “savings tool,” but experienced miles players know: the highest value of miles has never been redeeming cheap economy tickets — it’s redeeming business class and first class seats that you could never afford to buy with cash.
Taipei to Europe business class in peak season runs NT$150,000 or more. But with miles, China Airlines requires approximately 80,000 miles (one-way), EVA Air around 90,000. If each mile has a redemption value of NT$0.5–0.7, you’re trading NT$40,000–60,000 worth of miles for a seat that costs NT$150,000+ in cash. That’s the real magic of miles.
Where Do Miles Come From? The 3 Fastest Earning Methods in 2025
Rational Travel Guide
Is Your Trip Actually Bulletproof?
Most travelers discover missing visas, wrong connections, or closed hotels only after landing. Our 40-point Pre-Trip Audit catches everything — in 24 hours.
The most common beginner question: “I have zero miles — where do I start?” The answer is simpler than you think: get one miles credit card, join one airline’s loyalty program, and let everyday spending accumulate from there.

Miles come from three main paths:
Path 1: Earn from flying. Join China Airlines’ “Flying Miles Program” or EVA Air’s “Infinity MileageLands.” Each flight earns miles based on cabin class and ticket price. Business class typically carries 125%–200% mileage multipliers — meaning your one business class flight to Europe comes back with enough miles to start building toward another ticket. But it’s slow; accumulating enough to redeem through flying alone takes years.
Path 2: Miles credit card spending. This is the main engine. In 2025, mainstream miles credit cards earn approximately 1 mile per NT$10–15 of overseas spending, and 1 mile per NT$15–25 domestically. With NT$500,000 in annual overseas spending, you accumulate 30,000–50,000 miles per year — enough for a Europe business class redemption within three years. Find your best flight combination →
Path 3: Sign-up bonuses. This is the fastest shortcut for beginners. Many miles cards offer 5,000–20,000 bonus miles just for reaching a spending threshold within a specified window. Strategically apply for 2–3 cards, and sign-up bonuses alone can get you close to a short-haul business class redemption.
How to Read an Award Chart: China Airlines vs. EVA Air
For Taiwan-based travelers, the primary choice is China Airlines (SkyTeam alliance) or EVA Air (Star Alliance). The two programs don’t transfer between each other — pick one and focus.
China Airlines award redemption (one-way): TPE→Japan Business Class 30,000 miles; TPE→Europe Business Class 80,000 miles; TPE→North America Business Class 100,000 miles. EVA Air award redemption (round-trip): TPE→Japan Business Class ~50,000 miles; TPE→Europe Business Class ~170,000–200,000 miles.
Airlines don’t open every seat to miles redemption — only a limited number of “award seats” can be redeemed. These seats are scarce, and in peak season they’re gone in minutes. Strategy: start searching 6–11 months in advance (when booking opens, the most seats are available). Target off-peak flights. If your target trip falls in peak season and you’re searching last-minute, redemption is nearly impossible.
Upgrade Strategy: Getting Maximum Value from the Fewest Miles
Upgrades work two ways: pay cash for an upgrade before departure, or redeem miles for an upgrade seat. Using China Airlines as an example, short-haul miles upgrades require 8,000–20,000 miles; long-haul requires 30,000–60,000 miles.
Miles upgrades typically offer better value than cash upgrades because you’re trading accumulated miles — the marginal cost is essentially zero, provided you’ve been consistently earning. Upgrade award seats are also subject to availability, and they’re typically harder to secure than full award ticket seats in peak season.
Three principles for smart redemption: Redeem for high cash-value flights (same miles, higher cash price = better deal); avoid low-value redemptions (discount vouchers, shopping credits yield only NT$0.1–0.2 per mile); watch expiry dates (accounts expire after 3 years of inactivity — make at least one transaction per year to keep the account alive).
Redeeming miles directly for a business class award ticket is usually better value than using miles to upgrade — because upgrading requires buying an economy ticket first, then paying additional miles on top. If your goal is to sit in business class, the most efficient path is to accumulate enough miles to redeem a full business class award ticket directly, rather than buying economy and upgrading.

15 Most-Asked Miles Questions — Answered
Q1: I’ve never earned miles before. Where do I start?
The fastest starting point is applying for a miles credit card with a high sign-up bonus. Simultaneously, join the loyalty program of your main airline (China Airlines or EVA Air), and enter your member number every time you book a flight. Don’t try to juggle too many programs at once — focus on one airline for more efficient accumulation. First step: join the frequent flyer program (free), then choose a miles card.
Q2: What’s the difference between miles and rewards points? Which is worth more?
Miles (airline loyalty currency) are primarily used to redeem flights or upgrades. Rewards points are bank or retailer rebates — some transfer to miles, others only offset bills. Miles redeemed for business class tickets are typically worth far more than rewards points used as cash rebates. With the same NT$1,000,000 in spending, a miles card’s business class value can be 3–5× what you’d get from cash rebates.
Q3: Should Taiwan travelers accumulate China Airlines or EVA Air miles?
Key factors: which airline you fly most, which service you prefer, and which alliance partners you want to redeem. China Airlines is in SkyTeam; EVA Air is in Star Alliance. The two programs don’t transfer between each other. Choose one and focus — don’t split your miles across both.
Q4: When do miles expire? How do I prevent them from disappearing?
Most airline miles expire after 3 years of account “inactivity” — but any miles activity (spending, flying, transferring) resets the clock. Recommendation: make at least one miles card transaction per year to keep the account active. Warning: if you’ve accumulated 50,000 miles and leave them untouched, they’ll be zeroed out after 3 years — the most common tragedy for beginners.
Q5: Can I transfer or gift miles to someone else?
Most airline accounts don’t allow direct transfer, but you can use your miles to book tickets for family members (the beneficiary doesn’t need to be the account holder). Some airlines (like EVA Air) offer a paid miles transfer service. Third-party miles buying/selling violates most airline terms of service and risks account suspension — not recommended. The most practical legal option: book family tickets using your account directly.
Q6: Do miles awards still require paying taxes? How much?
Yes — award tickets still require payment of airport taxes, fuel surcharges, and other fees. For TPE–Europe, these fees can range from a few thousand to NT$10,000–20,000 depending on the airline and route. Some credit cards offer tax/surcharge subsidies — check before applying. Even with taxes included, a business class award redemption costs far less than the cash ticket price.
Q7: What is an “award seat” and why can’t I find one sometimes?
Airlines don’t make all seats available for miles redemption — only a limited number of “award seats” can be redeemed. These seats are scarce and gone in peak season in minutes. Award seat strategies: search 6–11 months in advance (most seats available when booking opens), target off-peak flights, or search partner airline award availability. If your target trip falls in peak season, start searching a year in advance.
Q8: Can I use miles to upgrade from economy to business class?
Yes — but you need a confirmed economy ticket first, then apply for a miles upgrade. China Airlines short-haul upgrades cost 8,000–20,000 miles; long-haul costs 30,000–60,000. Upgrade award seats are subject to availability and typically harder to secure than regular award tickets. Rational Life recommendation: if your goal is business class, accumulate enough miles to redeem a direct business class award instead of buying economy and upgrading — it’s almost always better value.
Q9: Are miles credit cards worth applying for? Is the annual fee justified?
Depends on spending habits. If you have more than NT$500,000 in annual overseas spending, miles card return rates typically outperform cash rebate cards. Annual fees: many banks offer first-year fee waivers or fee waivers with spending thresholds — confirm before applying. Key: you have to actually use and redeem the miles. Unused miles waiting to expire are wasted money. For low spenders with minimal overseas transactions, a cash rebate card is often more practical.
Q10: Can miles be used for first class?
In principle, miles can redeem any cabin class including first class — as long as award seats are available. First class requires the most miles and first class award seats are extremely rare. For flights departing Taiwan, first class redemptions are uncommon but not impossible. ANA’s first class has historically been the most sought-after redemption target among miles enthusiasts.
Q11: I’ve already bought an economy ticket — can I still upgrade?
Yes, several options: 1) Use miles to apply for an upgrade (usually best value); 2) Check the airline app or website for cash upgrade pricing (often cheaper than rebooking business class); 3) Ask at airport check-in about upgrade availability (occasional good prices). Start with miles upgrade, then consider cash. Note: cash upgrade prices are typically only released 72 hours before departure — don’t wait too long.
Q12: Does miles redemption have peak/off-peak differences?
Yes, but not exactly parallel to ticket price seasons. Award seat availability depends on how many seats airlines release — peak season typically sees fewer. But there are exceptions: some airlines open more award seats during peak periods to fill cabins. This requires pattern recognition through regular searching and experience. Simple rule: peak departure — start searching 6–11 months ahead; off-peak — 3–4 months usually yields availability.
Q13: Can miles be shared with family?
Miles accounts are personal, but most cards allow supplementary cards for spouses or parents — supplementary card spending earns miles in the primary account. This way, all family spending consolidates into one miles account, accelerating accumulation. Setup: primary cardholder joins an airline program, applies for supplementary cards for family members — everyone’s spending rolls into one account.
Q14: Is the “buy miles” service you see online legitimate?
Some airlines (like American Airlines, British Airways) offer official “purchase miles” services — these are legitimate, but per-mile purchase prices are usually not good value unless there’s a promotion (sometimes 30–50% off). Third-party miles trading (buying from individuals) violates airline terms of service and risks account suspension — not recommended. If you don’t have enough miles, the most reliable approach is strategically applying for high sign-up bonus cards.
Q15: For Taiwan travelers redeeming Europe business class, which program offers the best value?
Higher-value options for TPE–Europe business class currently include: 1) China Airlines miles for Europe business class (80,000 miles one-way, SkyTeam alliance); 2) Asia Miles to redeem Cathay Pacific business class; 3) ANA miles to redeem Star Alliance partner business class. Best choice depends on which program you primarily accumulate and whether your target flight has award seats available.
Fly Europe Business Class with Miles — Rational Life Advisory
Europe business class round-trip typically costs NT$150,000–200,000. Clients I’ve helped book with miles have paid NT$30,000–50,000 for the same flat bed. The difference isn’t “saving a bit” — it’s a whole additional trip budget freed up.
This isn’t a service for everyone. The one condition that makes it right for you: you have an important journey ahead and don’t want to waste money sitting upright.
