EVA Air is not as dominated by media coverage as some of its Star Alliance colleagues, but the Taiwanese airline has some very attractive redemption sweet spots especially when it comes to passengers looking to fly business without paying the hard cash prices that would require a second mortgage.

EVA Air is currently in the middle of a promotion in its Infinity MileageLands program that is giving up to a 40% bonus on miles purchased which reduces the cost per mile to as low as 2.8 cents each when purchased at the highest level. The question of whether that is really worth doing so hinges much upon what you are now intending to do with those miles and one particular program requirement making the calculus much different. Let's break it down.

How the Sale Is Structured

It is a progressive promotion, which is at a specific purchase level when you get the discount. You do not receive any bonus by purchasing less than 3 000 miles the 40 uplift begins at 3 000 miles of purchase and continues all the way to the maximum which is 150 000 miles purchase.

The following are the important terminologies that you should be conversant with prior to drawing your credit card:

• The 40 percent bonus is on purchases of 3,000 miles and over.

• The highest amount that can be purchased is 150,000 miles per year (paying 210,000 miles in total with the purchase price of 6,000)

• Miles have to be bought in batches of 1000.

• Unused purchased miles will fail to last longer than 36 months.

• Purchasing in U.S. dollar cost is normally priced lower by 2- 3 percent compared to buying in Taiwan Dollars.

• Sale ends March 26, 2026 at 11:59 a.m. ET

A practical remark: EVA Air makes purchase of miles on Points.com, so the purchase will not be coded as a purchase of an airline on your credit card. Not likely to cause any airline-specific bonus categories. The best thing to do is to use whatever card you are on top of some sort of welcome bonus, or even just your best everyday spending card.

The Idea of EVA Air Miles Worth having

It is useful to know where EVA Air miles shine before making a decision whether to purchase it or not. The redemption options of the Infinity MileageLands program are a few redemption options that are noticed among a large pool of airline award programs.

Gaining the most discussion is business on the U.S.Europe route at 65,000 miles one-way rate of 65,000, which is pretty healthy when contrasted to the charges that other members of the Star Alliance would charge the same cabin of which route. As an example, 65 000-mile flights in business class with a partner carrier will be a good redemption when the cash cost of these seats would be typically over 3000 to 5000.

Within the U.S some domestic transcontinental is offered domestically at 29,000 miles per way and this is competitive and profitable in the premium cabin medium between the coasts. And to the traveler with ambitions, EVA Air gives round-the-world award tickets a bucket-list redemption category that more programs do not back these days.

There is also useful flexibility in booking with the program: you are allowed to add up to two stopovers, open-jaw routing, or one-way awards. It is free to change dates on award bookings, eliminating one of the most frequent sources of pain. The negative is that fuel fees are charged on awards and hence your out of pocket amount at checkout will not be zero that you add to your value factor prior to booking.

The Rule That Changes Everything

This is where the section that should be singled out on its own deserves its own section, since this is the one most important thing you need to know before purchasing EVA Air miles; you cannot reserve an award ticket where over 50 percent of the miles flown are purchased.

Read that again. Assuming that you purchase 65,000 miles and you wish to redeem them to transatlantic business class, over half of the miles must have been earned by flying or some other means other than purchasing. Buy miles to redeem the miles begines a redemption just does not fly within this rule.

This, in practice, implies that EVA Air miles purchases are best employed as a top-up method in case you are near a redemption limit and require several thousand miles to reach it, the sale is very profitable. In the event that you begin with nothing, and have hopes of purchasing your way to a top-tier redemption, the program architecture is actively working against you.

It is a weird limitation, in contrast with most frequent flyer programs, and that is why EVA Air miles are not found in more buy miles now recommendations. It is a real opportunity, but a slim one.

Additional Ways to Earn EVA Miles without Purchasing

In an attempt to construct an EVA Air balance without hitting the 50 percent purchase threshold, it may help to know that the program does allow transfers between two major transferable points currencies. The points of the Citi ThankYou Points are transferred to Infinity MileageLands at a 1:1 ratio that is Citi cards are a natural feeder to this program. Transfers of capital one miles are also allowed, albeit at a less favorable 4:3 ratio, i.e. you will have to transfer more Capital one miles to obtain the same number of EVA miles.

In case you already have one of these currencies in hand and have a purchase in mind to redeem with EVA Air, it is almost always the superior bet to transfer rather than purchase particularly when you consider that they have a 50% purchase limitation to award tickets, especially award tickets.

Should You Buy EVA Air Miles Right Now?

The honest answer is: it depends on your specific situation. At 2.8 cents per mile with the 40% bonus applied, the price is fair for a Star Alliance program with access to some strong business class redemptions. But the 50% purchase rule fundamentally limits the audience for whom this sale is genuinely actionable.

If you already have a meaningful EVA Air balance and need to cross a redemption threshold before your miles expire or a partner award opens up buy now. The math works, the bonus is real, and topping up your account for a specific booking is exactly the use case this sale was designed for.

If you're considering buying miles speculatively stockpiling them without a specific redemption in mind the combination of a 36-month expiration clock and the 50% purchase cap makes this a much riskier proposition. Miles you can't easily use are miles you've paid for without getting value back.

The Bottom Line

The Infinity MileageLands program by EVA Air is being operated with a purchase bonus of 40 percent until March 26, 2026, which reduces the cost per mile to about 2.8 cents at the top level. This program has real worth to business class redemption especially of U.S. Europe routes and transcontinental domestic flights, but the restriction on award bookings of 50% purchased miles dramatically limits the beneficiary of this sale. It would be a nice promotion in case you are filling up an existing balance that will be redeemed in the near future. In the event that you are new Citi ThankYou transfers at a 1:1 ratio are probably the wiser course.
