Should You Buy Miles in 2026? When It Makes Sense (and When It Doesn't)

Buying miles is like pre‑paying for a trip that may or may not happen. When done wisely, it can unlock business‑class seats for a fraction of the cash price. When done poorly, it can leave you holding a depreciating currency. In 2026, airlines continue to run aggressive mileage sales, with bonuses as high as 160 %. But programmes also devalue without warning. This guide examines when purchasing miles is smart, when it isn’t, and how to avoid common pitfalls.

Understanding Mile Purchases: Why Airlines Sell Points

Airlines sell miles for one simple reason: it’s highly profitable. Loyalty currencies are a cash cow, often sold in bulk to banks and retailers. When airlines offer mileage sales directly to consumers, they’re essentially selling future transportation at a discount to raise cash immediately. You’re prepaying for travel, allowing the airline to collect revenue today and fulfil the promise later.

From a consumer perspective, buying miles can make sense under certain conditions:

1. To top up for a specific high‑value redemption. If you’re a few thousand miles short of a business‑class award, it may be cheaper to buy the difference than to pay cash for the whole ticket.
2. To take advantage of a generous bonus. Some sales reduce the effective price per mile to a level that can still yield value, particularly for premium cabins and long‑haul flights.
3. To avoid dynamic pricing. In programmes with fixed or semi‑fixed award charts, buying miles locks in a known cost rather than gambling on cash fares that can surge.

However, buying miles also has significant downsides:

1. Devaluation risk. Programmes can increase award prices with little notice. In late 2025, KrisFlyer raised Star Alliance award costs by 5–12 %. Avios followed suit in December 2025 with 8–14 % increases. If you buy miles speculatively and the programme devalues, your investment loses purchasing power.
2. Limited award availability. High‑value seats aren’t guaranteed, especially in dynamic programmes. If you can’t find award space, your miles may sit unused.
3. Cash is tied up. Miles are non‑refundable. You’re exchanging real money for a currency that typically can’t be converted back to cash.

Case Study: Avianca LifeMiles 160 % Bonus Sale

In March 2026, Avianca’s LifeMiles programme offered members up to a 160 % bonus on purchased miles. The sale allowed you to buy up to 200,000 miles (before the bonus) in a single transaction and up to 500,000 miles per year. The bonus was tiered: purchases between 1,000 and 20,000 miles earned a 140 % bonus, between 21,000 and 50,000 miles a 150 % bonus, and 51,000 to 200,000 miles a 160 % bonus. With the 160 % bonus, the price worked out to 1.27 US cents per mile.

LifeMiles noted that purchased miles are partially elite‑qualifying, but members still need to fly Avianca to reach status. The terms stipulated that purchases had to be in multiples of 1,000 miles, with a minimum of 1,000 miles per transaction and a maximum of 200,000 miles (excluding the bonus). The annual cap was 1,000,000 miles including bonuses. Each 1,000‑mile package cost USD 33.00 plus taxes and the purchase was non‑refundable.

On the surface, 1.27 cents per mile can be a great deal. LifeMiles is known for relatively low award pricing on Star Alliance partners and no fuel surcharges. For example, business‑class awards from North America to Europe sometimes cost 63,000 LifeMiles and under US$50 in taxes. At 1.27 cents each, that’s about US$800 plus taxes — significantly less than a cash fare.

But there are caveats. LifeMiles has a reputation for IT glitches and limited award availability in certain regions. Reader reports note difficulties booking some itineraries and instances where award space displays but cannot be ticketed. LifeMiles also sometimes devalues specific routes without broad announcements. Buying miles speculatively — without a specific redemption in mind — can thus be risky.

How to Evaluate a Miles Sale

Before pulling out your credit card, consider the following framework:

1. Define your goal. Are you topping up for a specific trip, or are you speculating? If you don’t have a near‑term redemption, think twice.
2. Calculate the effective cost per mile. Include taxes and fees. In the LifeMiles sale, 1.27 cents per mile is the headline figure, but your total cost depends on how many miles you buy and the taxes in your jurisdiction.
3. Compare with cash fares. Use tools like Google Flights or ITA Matrix to see what a cash ticket costs. Sometimes a paid fare (especially in economy) is cheaper than buying miles and booking an award.
4. Check award availability. Search for the routes and dates you want before buying. Tools like ExpertFlyer, SeatSpy or the airline’s own search engine can show you what’s realistic. Remember that dynamic pricing programmes may have little saver space.
5. Assess programme stability. Has the programme announced devaluations? Are rumours swirling about major changes? Review recent history — programmes like British Airways and Cathay Pacific have increased award costs within the last year.

Notable Programmes and Their Sale Patterns

While LifeMiles’ March sale grabbed headlines, many other airlines and hotels run periodic sales. Here’s a snapshot of patterns you might see in 2026. Note: specifics vary and promotions change, so always check current offers.

Programme	Typical Bonus Range	Regular Price per Mile/Point	Comments
Alaska Airlines Mileage Plan	40–60 %	2.75 cents per mile (before bonus)	Good for partner awards, but Alaska frequently raises award prices. Best to buy during 50 %+ bonus when cost dips below ~1.8 c per mile.
United MileagePlus	50–100 %	3.5 cents per mile	United miles rarely yield outsized value due to dynamic pricing. Consider only if you need a small top‑up for a saver award or to upgrade using PlusPoints (which will become dynamic in 2027).
American Airlines AAdvantage	35–70 %	3.5 cents per mile	AAdvantage miles can be valuable for partner awards on Qatar or Cathay Pacific, but the programme is experimenting with dynamic pricing.
Hilton Honors	80–100 %	1 cent per point	Hilton points generally value around 0.4–0.6 c each. Sales bring the cost to ~0.5 c, which can be worthwhile for high‑end resorts or if you need points for 5th night free redemptions.
Marriott Bonvoy	35–50 %	1.25 cents per point	Marriott points are usually worth ~0.6–0.7 c. Buying points rarely makes sense unless you’re topping up for a high‑value redemption.
Qatar Airways Privilege Club	50–70 %	3.5 cents per Avios	Avios purchases may be cheaper via British Airways or Iberia. Use caution; the programme has increased award pricing recently.

These figures are illustrative and vary by promotion. The key takeaway is that you should seldom buy miles at the base price. Wait for at least a 50 % bonus (or more) and always calculate whether the end redemption will be cheaper than paying cash.

When Buying Miles Makes Sense

1. You’re a few thousand short of a dream redemption. Topping up 5,000 miles to book a long‑haul business seat can be far more economical than buying a cash ticket or waiting months to earn the miles organically.
2. You find premium award space during a sale. If an airline releases saver seats and there’s an ongoing mileage sale, acting quickly can lock in value. For example, Business Class seats on ANA from Tokyo to North America for 75 k miles each way can be a steal when miles cost ~1.2–1.3 cents.
3. You need to extend point validity. Some programmes reset your mileage expiration clock when you buy or transfer miles. If your points are about to expire, a small purchase can keep them alive.

When You Should Pass

1. You’re speculating. Buying miles without a clear redemption plan is gambling. Devaluations can erode value overnight, as seen with KrisFlyer, Avios and Asia Miles within the past year.
2. Award availability is poor. Programmes like Delta SkyMiles and United MileagePlus rely heavily on dynamic pricing. If there’s little saver inventory, you might end up needing more miles than planned, negating any savings.
3. Cash fares are low. Sometimes airlines run paid fare sales that undercut the cost of miles. Always compare before pulling the trigger.
4. Your cash flow is tight. Remember that miles are not an investment asset. Don’t tie up money you need for other purposes.

Tips for Buying Miles Safely

1. Use the right credit card. Many mileage purchases are processed by Points.com and don’t count as airfare. Use a card that earns a high rate on everyday or travel spend. Avoid cards that add foreign transaction fees.
2. Stack promos. If possible, pair mileage sales with portal bonuses or credit‑card statement offers to reduce net cost.
3. Keep receipts and screenshots. If the bonus doesn’t post correctly, having documentation makes it easier to resolve issues.
4. Be mindful of account limits. Programmes cap how many miles you can buy each year. Exceeding the cap may forfeit your bonus.

Expert Commentary: Miles Mosaic’s View

Buying miles can be a powerful tool when used sparingly. As someone who has navigated dozens of mileage promotions, I’ve scored business‑class tickets for less than economy fares by buying miles at a discount. However, I’ve also seen readers stranded with large balances when programmes devalue. The pattern is clear: promotions are getting richer to stimulate short‑term cash, but devaluations come quickly thereafter. Treat miles like perishable goods — they’re most valuable when used soon after you acquire them.

At Miles Mosaic, we recommend logging your targeted redemption goals and comparing cash and award prices before every purchase. Our platform tracks mileage sales and alerts you to bonuses like the LifeMiles 160 % promotion, while highlighting recent devaluations so you can make informed decisions. Buying miles isn’t inherently bad, but doing it blindly is.

If you’re considering buying miles, let Miles Mosaic help with the due diligence. It aggregates sales, calculates effective cost per mile and compares award and cash prices for your routes. Make every purchase count.
