Frontier Airlines is running a promotion on purchased Frontier Miles, with a bonus of up to 150% depending on how many miles you buy. The offer runs through 11:59 p.m. Eastern on Friday, October 23, 2026. At the top tier, the effective cost works out to about 1.08 cents per mile once Frontier’s fee is included.
That’s a big discount from Frontier’s normal price, but buying miles only makes sense if you already have a specific trip in mind.
The bonus tiers
Frontier normally sells miles for 2.5 cents each, plus a 7.5% tax recovery charge added at checkout, or about 2.69 cents per mile all in. Here’s how the bonus changes that, as of October 2026:
| Miles purchased | Bonus | Cost per mile (before fee) | Cost per mile (with 7.5% fee) |
|---|---|---|---|
| 1,000 | None | 2.5 cents | About 2.69 cents |
| 2,000–4,000 | 100% | 1.25 cents | About 1.34 cents |
| 5,000–9,000 | 120% | About 1.14 cents | About 1.22 cents |
| 10,000–50,000 | 150% | 1.0 cent | About 1.08 cents |
Some examples at the top tier: buying 10,000 miles costs about $268.75 and gets you 25,000 miles. The maximum single purchase is 50,000 miles, which costs about $1,343.75 and becomes 125,000 miles with the bonus.
Key terms
- You need to buy at least 2,000 miles to get any bonus, and 10,000 or more for the full 150%.
- Miles are sold in 1,000-mile blocks, so you may end up with more than you need.
- Purchases are nonrefundable.
- Purchased miles don’t count toward Frontier elite status.
- Miles typically post within 24 hours, but don’t count on them showing up instantly if a fare is about to disappear.
- Frontier Miles expire if your account has no earning activity for 12 months, so don’t buy miles to sit on.
Who this makes sense for
Frontier award prices change with demand, so the only way to know whether this deal works is to do the math on a real trip:
- Search first. Find the flight you want and note both the cash fare and the miles price on Frontier’s site.
- Compare. Multiply the miles needed by about 1.08 cents, then add the taxes and fees charged on the award. If that’s clearly cheaper than the cash fare, buying may make sense.
- Watch the extras. Value tends to be best on the base fare. Bundles, bags and seat fees can eat into the savings, and on Frontier those extras are often where the real cost is.
- Top off, don’t stockpile. The best use is often buying just enough to finish off an award when you’re a few thousand miles short.
If you’re flexible and fly Frontier often, keep an eye on route news too. Frontier has been reshuffling its network this year, so make sure your route is still on the schedule before buying miles for a future trip.
Our take
A 150% bonus is a big one, and paying roughly 1.08 cents per mile can save real money on the right trip. But Upgraded Points, for example, values Frontier miles at about 1.1 cents each, so this price is close to what the miles are generally considered worth, not far below it.
That’s the catch: Frontier fares are often already cheap in cash, award prices move around, and the miles can expire after a year without activity. Buying speculatively is a gamble. For most travelers, we’d only buy if you’ve priced a specific award, confirmed it beats the cash fare after fees, and plan to book right away. Promotion details can change, so confirm the terms on Frontier’s buy miles page before you pay.
