United MileagePlus is currently selling miles with a bonus of up to 85% and an annual purchase limit of 175,000 miles. This isn’t the best deal we’re likely to see United offer this year but, as the math will show, there are definitely going to be times when miles purchased in this sale will save you money.

Buying Miles – The Math
Here’s the promotion as I’m seeing it in my MileagePlus account:
- Buy 5,000 – 29,000 miles and get a 40% bonus
- Buy 30,000 – 94,000 miles and get a 85% bonus
What that means in more useful terms is this:
- Buy 5,000 – 29,000 miles at a cost of ~2.69 cents/mile
- Buy 30,000 – 94,000 miles at a cost of ~2.03 cents/mile
To buy United MileagePlus miles at the best rate you would need to buy between 30,000 and 94,000 miles and, within this band, the cost per mile remains constant (more or less).
If you were to buy the full 94,000 miles allowed in this sale it would cost $3,536….
…and you would net 173,900 miles after accounting for the bonus.
That works out to be approximately 2.03 cents per mile.
Buying just 30,000 miles would still qualify you for an 85% bonus so the cost/mile remains the same – you don’t need to buy the maximum allowable number of miles to get the best rate.
Should You Miles In This Sale?
If you’re planning on hoarding the miles the answer to that question is simple – no!
Assuming you’re not planning on hoarding miles there are a few things to note:
- At 2.03 cents/mile this is not as good as some of the sales we’ve seen in which miles have been offered at 1.88 cents each….but this is still one of the better sales United publishes.
- There’s no scope for earning any extra credit card points/miles here (from bonus category spending) as the transactions are processed by Points.com and will earn just 1 point/mile per dollar.
- I value United MileagePlus miles higher than I value the miles issued by either Delta or American but I still value them considerably lower than the 2.03 cents selling price that’s on offer right now.
What this means is that unless I can see a very specific and immediate use for the miles (which would save me money) I wouldn’t buy miles in this sale.
My situation isn’t always the situation a lot of people find themselves in as I can be more flexible than most when it comes to booking flights.
This means that I don’t often find myself in a position where I’m forced to purchase fares that cost considerably more than I’m normally happy to pay.
A fact of life is that premium cabin fares are usually expensive (often very expensive) so, if you have no choice but to fly when fares are not in your favor, miles may help you save a considerable amount of money (as long as you can find award availability that works for you).
Here’s what I mean:
Roundtrip non-stop Business Class fares between San Francisco and Paris for June (on any airline) are currently pricing at no less than $3,908….
…..but, if you can find a Business Class United Saver award for dates that work for you, it would set you back just 120,000 miles + taxes.
120,000 miles in this promotion will cost approximately $2,436 so, even when you add in the taxes that you’ll have to pay out of Paris, you should still be able to make substantial savings.
Business Class fares on United’s Star Alliance partners are more expensive (140,000 miles for a roundtrip booking) so to book one of those with miles bought in this sale would cost ~$2,842….but that would probably still represent a saving in the order of $1,000 if you can find award availability.
This doesn’t just work for transatlantic routes, the savings across the Pacific can be even better.
If you take the example of a roundtrip non-stop Business Class fare between Chicago
and Tokyo in June the fares start at over $6,500:
If you’re lucky enough to find a saver award on United it will cost you 140,000 miles + taxes and, in this sale, the miles would cost ~$2,842.
A Star Alliance award would cost 160,000 miles on this route so an award would cost you around $3,047.63….or less than half of the cash fare.
Taxes on this route would be minimal so the savings could be fantastic….as long as you can find award availability in the first place – that’s key!
I can think of two scenarios in which buying miles in this promotion may be good idea:
- You need to top up a MileagePlus account with a small number of points to get you enough miles to book an award.
- You need to book an award to save money over a cash fare that you would otherwise have to buy.
If you fall into one of those two categories then here’s a link to buy some miles, if you don’t then this promotion is probably not for you.
Remember that this sale ends at 11:59pm CT on 1 March 2019 (Friday)
Most importantly: Do your research before you buy any miles and make sure the award you want to book is actually available before you add more miles to your account.
