EVA Air Offers Up to 40% Bonus on Miles Purchases Until March 26

EVA Air has launched a limited-time promotion for its Infinity MileageLands loyalty program, allowing members to buy miles with a bonus of up to 40 percent through March 26, 2025, creating a new opportunity to reduce the cost of award flights and upgrades across the carrier’s network and Star Alliance partners.

Key Details of EVA Air’s Limited-Time Miles Sale

The current promotion allows Infinity MileageLands members to purchase additional miles and receive a tiered bonus, with the highest levels of buying activity unlocking up to a 40 percent boost. Publicly available information indicates that the offer applies to both buying and gifting miles, and is targeted at members who need to top up their accounts for upcoming redemptions.

While EVA Air has not widely advertised a single global landing page for this specific sale, recent coverage of the airline’s buy-miles campaigns shows a pattern of bonus-based promotions in which members receive extra miles rather than a direct discount on the per-mile price. Historical data compiled by mileage-tracking sites suggests that the cost per mile during a 40 percent bonus typically settles just under 3 US cents, although the exact effective rate can vary slightly depending on the member’s billing currency and any applicable taxes or fees.

The promotion is scheduled to run until March 26, 2025, giving members a narrow booking window to decide whether to buy. Purchases are generally processed online through the Infinity MileageLands portal and are typically credited shortly after payment, which can be an advantage for travelers seeking to lock in award space they have already located.

Observers of EVA’s loyalty program note that similar campaigns in recent years have included caps on the total number of miles that can be purchased in a calendar year, as well as separate limits on how many miles can be bought in a single transaction. These limits are designed to keep the program balanced while still allowing substantial top-ups for premium cabin awards.

How the Bonus Changes the Effective Cost per Mile

Industry analyses of EVA Air’s past promotions indicate that a 40 percent bonus is toward the upper end of the airline’s recent buy-miles offers, though not unprecedented. Comparisons of past sales compiled by independent mileage sites show that EVA has alternated between percentage discounts on the base price and percentage bonuses on purchased miles, with effective costs often falling between roughly 2.4 and 3.0 US cents per mile during the most aggressive campaigns.

In a bonus-style promotion like the current one, the list price per mile remains the same, but members receive additional miles on top of what they buy. For example, a member purchasing 50,000 miles with a 40 percent bonus would receive 70,000 miles in total, although they pay only for the original 50,000. This structure reduces the effective cost per mile compared to standard pricing and can make certain redemptions more attractive, especially long-haul business or premium economy awards where cash fares remain high.

Even with the bonus, outside analysts generally describe EVA’s miles as sitting in the mid-range of airline loyalty valuations. Reports comparing major Star Alliance programs often rate Infinity MileageLands as offering solid value when miles are used strategically, particularly on EVA’s own premium cabins, but note that casual buyers should still run the math carefully to avoid overpaying for miles that might not be used efficiently.

For frequent flyers who are already planning specific redemptions, the promotion may offer modest but meaningful savings. For travelers buying miles speculatively, industry commentary tends to be more cautious, citing the risk of future devaluations and evolving award charts that can change the underlying value of a purchased mile.

Best Uses: EVA Premium Cabins and Star Alliance Awards

EVA Air’s Infinity MileageLands program is widely regarded by loyalty commentators as particularly appealing for long-haul premium cabin redemptions, where the carrier has built a reputation for service quality and onboard comfort. Analyses of the program’s zone-based award chart demonstrate that business class flights between Asia and North America or Europe can offer outsized value relative to the miles required, especially during peak cash-fare periods.

Several independent guides highlight that EVA allows one-way awards and offers flexibility such as open-jaw itineraries and stopovers on certain round-trip redemptions. This flexibility, combined with the current bonus on purchased miles, may enable travelers to design more complex itineraries that would otherwise require a larger cash outlay. For example, topping up an account to reach the mileage threshold for a transpacific business class award can be significantly cheaper under a bonus promotion than buying a comparable revenue ticket.

Beyond EVA-operated flights, Infinity MileageLands miles can be used on Star Alliance partners, including carriers across North America, Europe, and Asia. Publicly available program documentation confirms that members can redeem miles for partner-operated itineraries, though analysts often caution that partner award space can be more limited and may require additional flexibility in travel dates or routing.

For travelers based in regions served by EVA’s hubs and focus cities, the combination of alliance reach and premium product quality makes the miles more versatile. When the cost per mile is temporarily lowered by a bonus, some routes that previously offered only marginal value can become more compelling, particularly itineraries that would otherwise involve high fuel surcharges or last-minute fares.

Important Restrictions: Purchase Caps and the 50 Percent Rule

Travel forums and program overviews consistently point to an important caveat in EVA’s system: purchased miles can generally only be used to cover up to 50 percent of the total miles required for an award ticket. In other words, at least half of the miles for a redemption usually must come from flown activity or partner transfers rather than from miles bought directly in promotions like the current one.

This 50 percent limit significantly shapes how members can use the buy-miles bonus. Rather than enabling a traveler with a zero balance to purchase an entire award outright, the promotion is primarily designed as a top-up tool for members who already have a substantial mileage balance. Community discussions and user experiences shared on frequent-flyer forums indicate that misunderstanding this rule can lead to complications when attempting to ticket complex itineraries.

Alongside the proportional cap, EVA Air also imposes yearly limits on the number of miles a member can purchase or top up. Past documentation and promotional materials reference a ceiling in the range of 150,000 miles per calendar year, though the precise limit can vary by promotion and may be adjusted over time. Buyers considering a large mileage investment are encouraged by independent commentators to verify current caps within their online account before committing funds.

These structural constraints mean that the up to 40 percent bonus is most useful for travelers who already earn a meaningful number of miles from flying or credit card transfers, and who need a final tranche of miles to reach an award threshold. For those with small balances or no immediate redemption plans, the rules can diminish the practical value of the promotion.

How This Offer Compares With Past EVA Air Promotions

Historical tracking of EVA Air’s mileage sales shows that the airline has become a regular participant in the wider trend of loyalty programs monetizing miles through recurring discounts and bonuses. Data sets compiled by mileage-blog aggregators list a series of Infinity MileageLands promotions in recent years, including 40 percent discounts, 45 percent bonuses, and even higher limited-time offers tied to specific marketing campaigns.

In that context, an up to 40 percent bonus through late March 2025 fits squarely within EVA’s established promotional pattern. It is more generous than some recent campaigns that offered smaller discounts or bonuses, but it does not match the deepest deals in the program’s history, where effective rates per mile briefly dipped lower during special events. Analysts note that this middle-high positioning suggests EVA is seeking to stimulate demand from engaged members without significantly undercutting the perceived value of its currency.

Comparisons with other Star Alliance carriers’ mileage sales also show EVA near the middle of the pack. Some competitors periodically advertise steeper headline bonuses, but independent evaluations emphasize that the underlying award charts and surcharges must be considered alongside any promotional uplift. In many scenarios, travelers focused on EVA’s own long-haul premium cabins can still find competitive value even when headline bonuses are similar or slightly lower than rival programs.

For Infinity MileageLands members weighing whether to participate, the current offer appears most attractive to those with clear, near-term award goals and enough existing miles or transfer options to satisfy EVA’s 50 percent rule. For these travelers, buying miles with a temporary 40 percent bonus through March 26, 2025 can be a practical way to complete a high-value redemption while cash fares remain elevated on many international routes.
