How to Book United Flights With Partner Miles (Even If You Don’t Have United Miles)

Sometimes the most straightforward way to book a flight with points won’t work for you. Maybe you don’t have that specific kind of points. Or maybe there’s actually a cheaper way to book that flight using a different airline’s program.

Today we’re talking specifically about how to book United® flights even if you don’t have United miles — and even if you do, when it might make sense to book a different way.

This complements our guide to United’s MileagePlus® program. Here we’re going in the other direction: using partner airline miles to book United flights.

I want to be honest upfront: I really don’t think there are any true sweet spots for this domestically anymore. Pricing is about the same across most of these partners. But the advantage is that these partner miles are often easier to earn.

Why This Works: A Quick Refresher

MileagePlus® uses dynamic pricing, which means there’s no published award chart and United can charge whatever number of miles it wants on any given flight on any given day. The upside is that almost every flight is technically bookable with United miles — just sometimes the price is really high.

When airlines have a traditional award chart, they typically only release a certain number of seats to be bookable with points. United still has certain rates it calls saver pricing, and when a United flight is priced as a saver award, United typically makes that seat available for booking through partner airlines too.

If you can find saver availability on a United flight, there’s a decent chance you can book it with a partner program — sometimes for fewer miles than United would charge, and almost always with miles that are easier to earn.

The programs I’m covering today:

• Avianca LifeMiles®
• Air Canada Aeroplan®
• Singapore Airlines KrisFlyer®
• JetBlue TrueBlue® (through the new Blue Sky partnership)
• Turkish Airlines Miles&Smiles® (briefly — it used to be incredible and had a big devaluation)

One important note: using partner programs instead of MileagePlus® does come with tradeoffs. Almost across the board, cancellation policies are worse and there’s more friction in the booking process.

Avianca LifeMiles®

Avianca is a Colombian airline, and their loyalty program is LifeMiles®. For United bookings, LifeMiles® uses a fixed, region-based award chart. They divide the continental U.S. into three zones, and pricing is supposed to be based on which zones you’re flying between.

The regions don’t totally make sense — Florida, Illinois, and Montana are officially in the same region. And what I found when I was pricing itineraries is that they don’t always follow their own award chart anyway.

Their chart says awards within a U.S. region should be 10,000 points each way. But I found them pricing anywhere from 11,000 to 16,700 points. Chicago to Minneapolis came up at 11,000. Chicago to Montana and Chicago to Florida (supposedly the same region) came up at 16,700. For comparison, United was pricing those same routes around 15,000 miles, or 13,500 if you hold a United card. So in some cases LifeMiles® is more. In some cases it’s less.

Banks do occasionally run transfer bonuses to Avianca LifeMiles®. If you can catch a 20–30% bonus — so you transfer 10,000 points and get 13,000 miles — that can change the math, especially if you’re booking 4 or 5 tickets.

The biggest pro of Avianca is that it has the widest credit card transfer partner access of any program in this post including American Express®, Capital One®, Citi ThankYou® Points, Bilt, and Wells Fargo.

That said, I still can’t wholeheartedly recommend it. Here’s why:

• Cancellation fees. LifeMiles® charges $50–$200 per ticket to cancel and redeposit your miles, depending on the routing. Only use it when you’re pretty confident you’re taking the trip.
• Availability can be inconsistent on United routes.
• Customer service isn’t great. If you have to cancel or deal with a flight change, you’ll be doing it by phone, and their agents don’t always have the most knowledge to help you.

To be thorough, I’ll mention there’s an option to get a LifeMiles+ paid monthly subscription, which waives change and cancellation fees with 72 hours’ notice. That can make sense if you’re going to be a heavy user of this program.

Air Canada Aeroplan®

For a long time, Aeroplan® was one of the better options for booking United flights on a fixed chart. But in March 2025, Aeroplan® moved to dynamic pricing for United partner awards. Their dynamic pricing still seems to fall more or less within a defined range, so you can still find value.

For the continental U.S. routes I searched, Aeroplan® was about the same as MileagePlus® on pricing. I found a lot of routes pricing at 15,000 Aeroplan® miles, which is about the same as the United saver pricing I was seeing. Some shorter routes were priced for less — Chicago to Minneapolis came up at 10,000 miles for me, which is cheaper than United was showing for the same flight.

Like Avianca, Aeroplan® has a broad set of transfer partners: Chase, Amex, Capital One, and Bilt all transfer in. And like Avianca, Aeroplan® also sees periodic transfer bonuses.

The downsides:

• Cancellation fee: about $110 to get your points back
• Partner booking fee: about $30 on United awards booked through Aeroplan®. The good news is this is only charged once if you book a round trip, so it’s cheaper to book round trips than two one-ways.

Overall, Aeroplan® is going to be best for short flights when you only have Capital One or Amex and again you’re pretty sure you won’t cancel. It’s also a better value when you can book as a round trip.

Singapore Airlines KrisFlyer®

KrisFlyer® uses a flat rate for booking United domestic flights: 15,000 miles each way in economy for any continental U.S. route, regardless of distance.

That means a 40-minute hop from Chicago to St. Louis costs the same as a transcontinental flight from Newark to LAX. So it’s not a great deal on short flights, but it’s competitive with United on longer ones.

Where KrisFlyer® has the best deal is to Hawaii. From the mainland U.S. to Hawaii, KrisFlyer® charges 20,500 miles each way in economy. MileagePlus® typically prices the same flight around 25,000 miles, or 22,500 if you hold the United card. That’s 2,500–4,500 points of savings per person, per direction. It doesn’t sound huge for one person, but for a family of four flying round trip to Hawaii, that’s up to 36,000 miles in savings.

KrisFlyer® is also a transfer partner of all four major U.S. credit card currencies: Amex Membership Rewards®, Chase Ultimate Rewards®, Citi ThankYou® Points, and Capital One miles.

Some caveats:

• Transfer times: Amex is typically fast. Capital One and Chase can take closer to 12–24 hours.
• Fees: Changes are $50 per person and cancellations are $75 per person.

Of all these programs, this is hands-down the best one for Hawaii if you’re pretty certain you’re going to take the trip. It’s also a decent option if you have Capital One, Amex, or Citi points and you want to fly a United route you’re confident you won’t need to cancel.

A Quick Note on Turkish Miles&Smiles®

Turkish used to be the cheapest program for booking United domestic flights, especially to Hawaii — and a lot of older content out there still references those old rates, which no longer exist.

In December of 2025, with zero advance warning, Turkish raised their domestic United rates. All continental U.S. routes went from 10,000 miles to 15,000 miles each way in economy — a 50% increase overnight. Hawaii got hit even harder, going from 10,000 miles to 25,000 miles each way. That’s a 150% increase.

Turkish was always a huge pain to deal with. People would search for flights, try to call in, have to email their itineraries, then wait up to a week. But it was worth putting up with for Hawaii because the pricing was half price versus booking with United.

Now that it’s the same price as everyone else — and now that Singapore KrisFlyer® is cheaper or the same on all these routes — there’s really no reason to look at Turkish for domestic United flights anymore.

JetBlue TrueBlue® (The Blue Sky Partnership)

United and JetBlue launched a partnership called Blue Sky in October 2025. TrueBlue® members can now book United flights using JetBlue points, and vice versa.

JetBlue’s pricing for United flights is dynamic, and rates are all over the place.

Highest pricing was on longer flights to to Hawaii:

• Newark to LAX flight was 40,000 TrueBlue® points (whereas the other airlines were around 15,000 for that same flight)
• US Mainland to Hawaii was also 40,000 points or more

Shorter routes came up more competitively and matched other programs:

• Chicago to Minneapolis at 10,000 points
• Chicago to Denver at 15,000 points

But JetBlue’s biggest advantage is that it doesn’t charge a cancellation fee. You can cancel your flight and get your TrueBlue® points right back into your account for no extra cost. From what I can tell, they may keep your taxes and fees as a flight credit, but that’s just $5.60 each way within the U.S.

Keep in mind that changes are not permitted on United flights booked with JetBlue. So you’d want to book everything as separate one-ways, and if you need to change just one leg you’d cancel that leg, get your miles back, and rebook.

Not all of JetBlue’s transfer partners are good, either. Amex and Capital One transfer at less than 1:1, so avoid them unless there’s a transfer bonus. Citi still transfers 1:1, as do Chase and Wells Fargo. JetBlue also has several credit cards with decent bonuses (issued by Barclays — which is nice because that’s a different bank from most of what people are applying for), and the JetBlue business card can be a good option if you’re just trying to get another card and stay under 5/24.

The main use case for JetBlue here is those 10,000- or 15,000-point short-to-medium routes when you find them — especially when there’s a chance you might need to cancel.

My Actual Booking Workflow

There’s no simple workflow for this. But here’s roughly how I approach it.

1. Check for transfer bonuses first. This can influence which program is your best option before you even start searching.
2. Start your award search on united.com or seats.aero. United.com is free, so if you don’t have a Seats.aero account, you can use that. Search your route, and if you’re flexible, use the 30-day calendar.
3. Look for flights marked as saver pricing. That’s a really good indication you’ll be able to find them bookable with other airlines. Seats.aero doesn’t add a ton on top of United’s site for this — it really only pulls Aeroplan®, United, and JetBlue pricing. It doesn’t pull Avianca LifeMiles® or KrisFlyer® anyway.
4. For Hawaii, go straight to singaporeair.com. If you see availability at the 20,500-mile rate, that’s your confirmation. But don’t transfer yet.
5. Always confirm the seat is actually available on the partner’s own website before transferring any points. This is the rule I cannot repeat enough, whether you’re using LifeMiles®, Aeroplan®, or KrisFlyer®. LifeMiles® in particular is notorious for showing phantom availability that disappears the moment you try to click through and book. Transfers are one-way and irreversible. So: confirm first, transfer second, book immediately.

My Ranking (For When You Don’t Have United Miles)

There’s no clear winner, but here’s how I’d rank these programs beyond just booking directly with United:

Short flights → JetBlue is the best option if it’s pricing at 10,000 points — the 1:1 transfer partners are limited, but the free cancellations make it worth prioritizing when you can use it. Even some medium-range flights can come up competitive at 15,000 points each way.

Short flights when JetBlue isn’t an option → Aeroplan®. Just keep those steep $110 cancellation fees and $30 booking fees in mind.

Hawaii → Singapore KrisFlyer® 20,500 points each way from anywhere in the continental U.S. to Hawaii is the cheapest option out there.

Everything else within the continental U.S. → Pricing is pretty similar through Aeroplan®, KrisFlyer®, and Avianca LifeMiles® — typically right around 15,000 miles, which is usually about the same as United is charging. So your deciding factor often comes down to which one has an active transfer bonus.

One more note: Avianca has the lowest cancellation fee at $50, but customer service is probably the worst. So factor that in, or at least be prepared mentally if you have to deal with an issue.

Don’t Forget to Check Cash Prices

Before you wrap up your research, one more thing: transferring points to a partner to book a United flight might not be the best use of your points at all.

You should always be looking at the cash prices for those United flights too. Sometimes you’ll find that booking via Capital One Travel (or another portal) will actually use fewer points overall than transferring to a partner.

A lot of people get bad advice that you should never use travel portals — that transferring is always better. That just isn’t true. Check those cash prices as part of your research too. Here’s more on travel portals and what to know.

The Bottom Line

There’s no clear winner when it comes to booking United flights with a partner airline, but there are some decent options depending on your situation. For most domestic routes, pricing ends up in the same ballpark as MileagePlus®, and the real deciding factors are which transfer partners you have access to, whether there’s an active transfer bonus, and how confident you are about not needing to cancel.

The two situations where partner programs stand out are Hawaii via Singapore KrisFlyer® and short routes via JetBlue when you want free cancellation flexibility. Everything else is basically a wash, which is okay — the point of this post isn’t to find you a 90%-off deal, it’s to show you that you have options even when you don’t have United miles.
