What United Airlines offers and how its rewards program compares

United Airlines operates a frequent flyer program called MileagePlus, where you earn miles for flights and can redeem them for future travel, seat upgrades, or other rewards. Miles accumulate based on the distance you fly, not the price you pay, so a cheap cross-country ticket earns the same miles as an expensive one on the same route. You can also earn miles through credit cards, hotel stays, car rentals, and shopping partners.

The program has four membership tiers — General Member, Silver, Gold, and Platinum — each offering different perks like priority boarding, free checked bags, and lounge access. You move up tiers by flying a certain number of miles or segments in a calendar year. Unlike some airlines that reset your account if you don't fly for a period, United keeps your miles indefinitely as long as your account has activity at least once every 24 months.

United's redemption rates vary by route and travel date. A domestic flight might cost anywhere from 12,500 to 50,000 miles depending on demand, time of year, and how far in advance you book. International flights typically start around 30,000 miles for short-haul and 60,000 miles for long-haul, but peak pricing can double those amounts. You can also use miles to bid for upgrades on flights you've already booked.

Key Takeaways

  • MileagePlus miles are earned per distance flown, not per dollar spent, so you earn the same miles on a $200 ticket and a $800 ticket on the same route.
  • Redemption costs vary by route and date — the same destination can cost 20,000 miles in off-season or 50,000 miles during peak travel.
  • United keeps your miles active indefinitely if you have any account activity within 24 months, including credit card spending or partner transactions.
  • Tier status is based on miles or segments flown in a calendar year, and each tier unlocks benefits like free checked bags, priority boarding, and lounge access.

How to earn MileagePlus miles outside of flying

You don't have to fly to accumulate miles. United credit cards offer sign-up bonuses ranging from 40,000 to 100,000 miles depending on the card and current promotions. These cards also earn miles on everyday purchases — typically 1 to 4 miles per dollar spent, depending on the card type and merchant category.

Partner programs let you earn miles through hotel chains (Marriott, Hilton, IHG), car rental companies (Hertz, Avis, Budget), and shopping portals. When you book a hotel through United's site or use a partner code at check-in, you earn miles on top of any hotel loyalty points. Shopping portals work by clicking through to retailers like Amazon, Best Buy, or Target from United's website — you earn a set number of miles per dollar spent.

Dining programs also award miles. United has partnerships with restaurants in certain cities where you can earn miles by paying with a linked credit card or presenting a code at checkout. The earning rate and participating restaurants change, so check United's website for current options in your area.

Seat selection, upgrades, and what they cost

United assigns seats automatically when you book, but you can change your seat for free if you're a Silver member or higher, or if you have a United credit card. Standard Economy seats are free to select. Preferred Economy seats — typically extra legroom in the front of the cabin — cost between $15 and $100 per flight depending on route and how close to departure you book. Premium Plus and Business Class seats must be purchased separately or redeemed with miles.

Upgrades work in two ways. If you're booked in Economy, you can bid for an upgrade to a higher cabin using miles or cash. United sends upgrade offers to frequent flyers after booking, and you can also manually place a bid through your reservation. The cost depends on demand — a short domestic flight might cost 5,000 miles, while a cross-country flight could cost 15,000 or more. You can also use a complimentary upgrade certificate if you have one from your tier status or credit card benefits.

Standby upgrades happen automatically at the gate if you're may be able to access. Silver members and higher get automatic complimentary upgrades if space is available, processed in order of tier status and then by frequent flyer status. If you're not automatically upgraded, you can still bid for an upgrade at the gate, though availability is usually limited by that point.

How MileagePlus tiers work and what each level includes

The four MileagePlus tiers are earned by flying a minimum number of miles or segments in a calendar year. General Member is the base level with no requirements. Silver requires 25,000 miles or 10 segments. Gold requires 50,000 miles or 30 segments. Platinum requires 75,000 miles or 50 segments. Each tier resets on January 1, so miles and segments flown in December count toward the next year's status.

Silver members get one free checked bag, priority boarding, and a 10% mileage bonus on all flights. Gold members add a second free checked bag, United Club passes (usually two per year), and a 25% mileage bonus. Platinum members get lounge access, a third free checked bag, and a 50% mileage bonus on miles earned. All tiers above General Member also get priority customer service phone lines and the ability to change flights without a fee.

You can also buy status through a program called PlusPass, which grants you Silver or Gold status for a set price without flying. This is useful if you're close to a tier but won't reach it by year-end, or if you want the benefits without committing to a certain number of flights. PlusPass pricing varies and is typically announced in the fall for the following year.

Redeeming miles for flights and other rewards

To redeem miles for a flight, log into your MileagePlus account and search for available award flights on your desired dates. United shows you the mile cost for each flight option. You can book one-way or round-trip awards, and you can add a stopover on round-trip awards to visit a second destination. Stopover rules vary by region — domestic stopovers are usually free, while international awards may allow one stopover depending on the routing.

Miles can also be redeemed for seat upgrades, hotel stays through partner programs, car rentals, and gift cards. The value per mile varies — a hotel redemption might be worth 1 cent per mile, while a flight redemption could be worth 1.5 cents or more depending on the route. You can also transfer miles to airline partners like Air Canada, Lufthansa, or ANA, though the transfer rate is usually not favorable unless you're targeting a specific award on a partner airline.

Award availability changes constantly. Popular routes and dates book up quickly, especially during peak travel seasons. United releases award inventory in waves, with some seats available at booking and others released closer to the travel date. Searching for flexible dates or less popular routes often shows more availability at lower mile costs.

Fees, restrictions, and what to know before booking

Award flights are subject to the same change and cancellation rules as paid tickets, but the rules differ by ticket type. Basic Economy awards cannot be changed or cancelled for a refund — you lose the miles. Main Cabin awards can be changed to a different date or route for free, but if you cancel, you get your miles back minus a $0 fee (meaning you get all your miles back). Premium cabin awards have similar flexibility.

Fuel surcharges do not explore to award flights, which is one advantage over paying cash. However, you still pay taxes and fees on award bookings — typically $5 to $15 for domestic flights and $15 to $50 for international flights depending on the destination. These fees are non-refundable even if you cancel the award.

Award flights are subject to seat availability, which means you might not find award space on your preferred flight even if paid seats are available. United does not may provide award availability, and popular routes can have limited or no award inventory on certain dates. Booking further in advance usually increases your chances of finding space.

How MileagePlus miles expire and how to keep your account active

MileagePlus miles do not expire as long as your account has activity within a 24-month period. Activity includes flying on United, earning miles through a credit card, redeeming miles, or earning miles through partner programs. If your account is inactive for 24 months, your miles will expire, though United typically sends a warning email before that happens.

The easiest way to keep your account active is to use a United credit card for everyday purchases — even a small transaction counts as account activity. You can also earn miles through hotel or car rental partners without flying. If you're concerned about expiration, you can also transfer miles to a family member's account or donate them to a charity partner, though transfers may have restrictions or fees depending on your tier status.

If your miles do expire, you may be able to reinstate them by contacting United customer service, though this is not may provide and may require proof of activity or payment of a reinstatement fee.

Frequently Asked Questions

Do I earn the same miles on a cheap ticket as an expensive ticket?

Yes. United miles are based on distance flown, not the price you pay. A $150 cross-country ticket and a $600 cross-country ticket earn the same miles. You do earn bonus miles if you pay for a higher cabin (Premium Plus or Business Class), but the base earning is the same regardless of ticket price.

What happens to my miles if I don't fly for a year?

Your miles stay active as long as you have any account activity within 24 months. Using a United credit card for purchases, booking a hotel through a partner, or redeeming miles all count as activity. If your account is completely inactive for 24 months, your miles expire, but United sends warning emails before that happens.

Can I use miles on other airlines?

You can transfer miles to United's airline partners like Air Canada, Lufthansa, ANA, and others, but the transfer rate is usually not favorable. Most people find better value redeeming miles directly on United flights. Some partners also allow you to book their flights using United miles through United's website without transferring.

How far in advance should I book an award flight?

Award availability varies by route and date. Popular routes and peak travel dates can fill up quickly, so booking 2 to 3 months in advance increases your chances of finding space. Less popular routes and off-peak dates often have availability closer to the travel date, but you have fewer options to choose from.

What's the difference between a Basic Economy award and a Main Cabin award?

Basic Economy awards cannot be changed or cancelled for a refund — you lose the miles if you need to cancel. Main Cabin awards can be changed to a different date or route for free, and you get your miles back if you cancel. Main Cabin awards typically cost more miles than Basic Economy on the same flight.
