Flying United Polaris out of San Francisco is rarely affordable if you pay full cash. Fares often hover around $3,500 to $5,000 one-way to Asia or Europe. With the right mix of partner miles and cash co-pays, you can bring that number down to less than a quarter of the sticker price.
The strategy is not just knowing which programs book Polaris, it is knowing which ones actually deliver value from SFO, United’s largest international hub.
The Best Value Programs
Here is a comparison of the most practical redemptions for Polaris flights from San Francisco:
| Program / Currency | Typical Cost (One-Way Polaris) | Taxes & Fees | Why It Matters |
| Turkish Airlines Miles&Smiles | 45,000 miles | $5.60 | Lowest redemption rate, but difficult to book and limited space. |
| Avianca LifeMiles | 63,000 miles | $25 | Strong balance of cost and usability, no surcharges. |
| Air Canada Aeroplan | 70,000 miles | $60–100 | Easier booking tool and flexible routing options. |
| United MileagePlus | 80,000–100,000 miles | $5.60 | Consistent access to award space, but usually costs more. |
| Cash + Miles Upgrades | Varies (e.g., $600 + 20K miles) | Varies | Useful if you already hold a Premium Plus or higher fare. |
Turkish Airlines Miles&Smiles
This program offers the lowest published rate for Polaris to Europe from SFO at 45K miles one-way. Taxes are minimal. The challenge is execution. Turkish’s website is clunky, and booking often requires patience with call centers. If you are willing to put in the effort, this is the most affordable redemption available.
Avianca LifeMiles
LifeMiles is often the sweet spot for travelers who want simplicity. At 63K one-way with no fuel surcharges, it is one of the most consistent and realistic ways to secure Polaris. Transfers from Amex, Chase, Citi, and Capital One make it accessible, and availability usually matches what United shares with partners.
Air Canada Aeroplan
Aeroplan costs slightly more at 70K but has advantages. The booking interface is reliable, and Aeroplan allows mixed itineraries. If you want to book SFO–FRA on United and continue FRA–ATH on Lufthansa, Aeroplan handles that in one reservation. For many travelers, the extra 7K miles is worth the ease.
United MileagePlus
United keeps some of the best award seats for its own members, so at times MileagePlus is the only option to access SFO departures. Expect to pay 80K to 100K miles one-way. It is rarely the best deal, but it remains the most reliable path when partners show nothing.
Cash and Miles Upgrades
If you are booked in Premium Plus, Polaris upgrades from SFO typically run 20K miles plus $500 to $700. This option can be cost-effective when economy fares are low, especially if your travel dates are not flexible. The downside is risk, since upgrades clear based on status and availability.
How SFO Changes the Game
San Francisco is different from other United hubs. Competition for upgrades is tougher because of the large pool of high-status flyers based here. At the same time, SFO has one advantage: volume. Multiple daily Polaris flights operate to London, Frankfurt, Tokyo, Hong Kong, and beyond. With more departures, you have more opportunities to find open award space if you are flexible on dates and destinations.
The Bottom Line
The most affordable way to book Polaris from SFO is Turkish Miles&Smiles at 45K, though most travelers will find Avianca LifeMiles at 63K to be more practical. Aeroplan comes close behind, and MileagePlus fills the gaps when partner options are unavailable. If you already booked Premium Plus, cash and miles upgrades can work in your favor.
Polaris is rarely worth paying full fare out of pocket. For travelers who plan strategically, miles and mixed-cash approaches turn what looks like a $4,000 seat into something attainable for less than $700 out of pocket plus points.
