EVA Air Selling Miles With up to a 40% Bonus — But Is It Worth Buying?

Why It Matters

The promotion provides a quick mileage boost for imminent business‑class redemptions, but the 50 % cap and lack of status credit limit its appeal for long‑term mileage building.

Key Takeaways

• 40% bonus reduces price to 2.86¢ per mile
• Purchased miles must be ≤50% of redemption
• Miles expire 36 months after purchase
• Promotion ends March 26; 35% bonus until April 10
• Ideal for high‑value business class award gaps

Pulse Analysis

EVA Air’s latest Infinity MileageLands promotion, running through March 26 2026, offers a 40 % bonus on purchased miles, bringing the effective price to roughly 2.86 ¢ per mile (about $6,000 for 150,000 miles). While not the deepest discount on the market—programs such as Avianca LifeMiles or United MileagePlus have run sub‑2 ¢ offers—the deal is competitive for travelers focused on Star Alliance routes. Converting the Taiwanese‑dollar price (193,050 TWD) yields roughly $6,045, confirming the U.S.‑dollar pricing as the cheaper option.

The promotion’s most significant constraint is the 50 % redemption cap: purchased miles can cover at most half of any award, requiring earned miles to fill the remainder. This rule, combined with EVA’s carrier‑imposed fuel surcharges, narrows the sweet spot to high‑value business‑class awards where the cash price far exceeds the mileage cost. Sample calculations show a United transcontinental business award can be secured for $826 versus $3,800 cash, and a U.S.–Europe Star Alliance ticket drops from $5,923 to $1,857 when miles are bought at the promotional rate.

Frequent flyers with flexible credit‑card points (Citi, Capital One, HSBC) often achieve better value by transferring to EVA at a 1:1 ratio, avoiding the 50 % limit and preserving status‑earning potential. United MileagePlus also provides deep‑discount mile purchases without expiration, making it a viable alternative for Star Alliance itineraries. In summary, EVA’s 2.86 ¢/mile sale is a tactical tool for imminent redemptions, but most travelers will benefit more from point transfers or waiting for a deeper discount.
