United Airlines’ MileagePlus Program 2025 Guide: How to Earn, Redeem and Save

One of the best ways to use United miles is for free flights on United Airlines or its Star Alliance airline partners. First, let’s look at booking flights on United.

The United award chart used to be the first stop for determining the number of miles needed to book an award ticket. With the move to dynamic pricing, however, you’ll simply need to head to united.com and plug in your origin, destination and date(s) of travel to find out how much an award ticket costs. Make sure to also check the button that says “book with miles.”

You can book awards over the phone, but United’s website has a sophisticated award search that will return plenty of results — plus, you can avoid the $25 phone booking fee the airline typically charges if you’re not an elite member.

United has two levels of awards for each cabin class: Saver and Everyday:

• Saver awards are cheaper, but availability at this level is limited.
• Everyday award seats are plentiful, but the value per mile is lower than Saver awards.

There’s no difference between the awards aside from these factors.

Because this frequent flyer program uses dynamic pricing, United award flight prices vary substantially. They also vary based on the cabin class and when you’re flying, as well as your city of departure and destination. Consider the following examples to see what we mean.

Example: We found Economy Saver Award prices for an early morning short hop from San Francisco to Los Angeles as low as 7,700 miles in August 2026, while a first-class Everyday Award for the same hop clocked in at 30,000 miles. For either flight, airline taxes and fees were $5.60.

Example: Transcontinental flights from Las Vegas to Newark, N.J., were as low as 15,000 miles plus $5.60 one-way in economy over dates in July 2026. For the same flight in first class, you could fork over 64,400 miles plus $5.60.

Maybe you want to use your miles for a tropical vacation in the Caribbean. In that case, we easily found flights from Newark, N.J., and other major U.S. cities to Aruba in the main cabin economy for as little as 22,900 miles plus $15.60 in airline taxes and fees in June 2026.

Flights between the U.S. and other continents are subject to variable pricing as well. It used to be easy to calculate the cost for a Saver Award using the United award chart, but that’s no longer an option.

Examples: As shown below for an itinerary in April 2026, flight awards between Chicago and Paris can run as low as 31,200 miles plus $5.60 one-way in main cabin economy. However, the same flight can cost just under 200,000 miles plus $5.60 in United’s business class.

You could also use United miles to fly somewhere more remote than Europe, and potentially get a great deal in the process. For example, we found one-way main cabin economy flights from Newark, N.J., to Dubai in the United Arab Emirates for 40,000 miles plus $7 over dates in April 2026. For the same flight in United Polaris Business class, the cost came out to 220,000 miles plus $7.

You could even use your miles to fly from L.A. to Singapore in economy class for a total cost of 36,100 miles plus just $5.60 in airline taxes and fees. This is an excellent redemption for an itinerary that can take more than 20 hours and may cost more than $800 if you pay in cash.

United’s airline partners are a big part of what makes United miles so valuable. Booking on Star Alliance partners can offer some of the highest-value United award redemptions. You can find especially good values when choosing business or first class on airlines known for their incredible in-flight experiences.

As an example, we found nonstop, one-way award flights from Frankfurt, Germany (FRA) to Buenos Aires, Argentina (EZE) on partner airline Lufthansa over dates in April 2026 for 50,000 miles plus $150.10 in main cabin economy and 100,000 miles plus $150.10 in business class. This is a great deal considering the cash price of similar itineraries on Lufthansa that you can book with United miles can set you back around $862 and $15,526, respectively.

You can also use your miles to make your upcoming flight much more comfortable and luxurious by snagging space in a premium cabin. Here are four ways you can get an upgrade with United miles:

1. Get a United upgrade during booking. You can request a United upgrade award during booking. To do so, sign in to your MileagePlus account and choose “Advanced search options.” Search for your flight and choose “MileagePlus Upgrade Awards (MUA).” If no flights show upgrade availability, you can book and request an upgrade later.
2. Request a United upgrade after booking. You can get an upgrade after booking in several ways: You can sign in to your MileagePlus account and pull up your reservation to make the request online, call your dedicated Premier elite service line or United Reservations at 800-UNITED-1 (800-864-8331) or talk with a United representative at a check-in counter or at the gate within 24 hours of departure.
3. Choose a PlusPoints upgrade. You can also get what United calls a PlusPoints upgrade during or after booking a flight on United or a partner airline. However, this option is only available to eligible elite status members.
4. Get a Star Alliance upgrade. You also may be able to use United miles to buy a one-cabin upgrade on eligible flights on certain Star Alliance partner airlines. You can request these upgrades for up to four people on the same itinerary.

Using United miles for upgrades can be a good way to use your rewards and, depending on the upgrade and the flight, can offer an excellent value.

Award flights are by far the best way to redeem your United MileagePlus miles, as you’ll generally get more than 1 cent per mile based on LendingTree’s valuation. However, there are other redemption options if you don’t wish to book flights, including:

• Airport dining: Use miles to pay for meals at select airports, including Newark Airport (EWR) and Houston Intercontinental Airport (IAH).
• Car rentals: You can use miles to book a rental car with Avis and Budget through the MileagePlus Car Awards booking portal.
• Checked bag fees: Use your United miles to pay for checked bag fees.
• Cruises: Redeem your United miles for cruises to many destinations.
• Experiences and events: You can use your miles to book unique events and experiences.
• Hotel stays: You can use your miles to book stays at hotels and resorts around the world by using the United Hotels booking portal.
• In-flight Wi-Fi: Use your miles to pay for in-flight Wi-Fi on United flights.
• Newspapers: Use your United miles to subscribe to your favorite newspapers.
• Gift cards: Use your United miles to buy electronic gift cards from a variety of retailers and restaurants, from Apple and Lowe’s to Starbucks and Walmart.
• Merchandise: You can use the MileagePlus Merchandise Awards portal to shop with United miles for merchandise, from electronics and luggage to jewelry and sports equipment, from a variety of retailers.
• TSA PreCheck^®: Use your United miles to give yourself the gift of a speedy and more convenient trip through airport security.
• United Club membership: Redeem United miles for an airport lounge membership so you can have space to rest or work between flights.

Generally speaking, redeeming miles in these ways will yield less value than award flights. For example, redeeming United miles for hotel stays, car rentals or TSA PreCheck^® membership will typically yield less than 1 cent per mile. That’s why it’s highly recommended you redeem your miles for award flights over other options.

Consider getting a United credit card if you want frequent flyer benefits like free checked bags and priority boarding. You should also note that airline credit cards let you earn miles for each dollar you spend, and United credit cards offer generous sign-up bonuses on top of miles for regular spending.

It’s totally free to sign up for United MileagePlus, so you can get a frequent flyer number and start earning miles that can get you free flights and other rewards. However, you’ll need to spend money with United and its partner airlines, or sign up for a United credit card, in order to earn enough miles to make the program worthwhile.

If you’ve misplaced your MileagePlus number, head over to the Forgot MileagePlus number link. From here, you can enter your first name, last name, email address and date of birth and click the “Submit” button. United will then send you an email with your MileagePlus number. If you don’t get an email or still need help finding your MileagePlus number, you can call the MileagePlus service center at 800-421-4655.

You can transfer MileagePlus miles to another member with United’s miles pooling feature. Miles pooling is free and easy, although you have to be 18 years old to initiate a new pool.

You cannot add family members to your MileagePlus account. Each family member ages 18 and older must create their own account. You can also create an account for your children if they are under the age of 18.

United Airlines MileagePlus members can submit a request for mileage credit online for United flights dating back six months. To request mileage credit for other travel bookings, you must call the MileagePlus Service Center at 800-421-4655.

You can request to merge United Mileage accounts if you have more than one account. Requests can take up to seven days to process. Note that your full name and birthdate must match between the accounts to be eligible to merge them.
