When Do United Miles Expire?

United Airlines announced on August 28, 2019, that United miles will no longer expire effective immediately. Previously, miles expired after 18 months of account inactivity. United required MileagePlus members to earn or redeem miles at least once every 18 months to reset the clock.

United’s policy change now puts them in the same camp as Delta SkyMiles and Southwest Airlines Rapid Rewards. Neither frequent flyer program expires their miles due to account inactivity.

While your miles no longer expire, it’s still a good idea to log into your account regularly and verify your email address. For good measure, you can also try earning miles at least once a year. If United can’t contact you, they may close your account by accident.

Reclaiming Expired Miles

It’s still possible that you may have had United miles expire before the policy change. If your miles have expired within the last 18 months, you can reclaim them. But it’s going to cost money.

United offers two different ways to reinstate miles.

Buy Back Miles

You can reinstate up to 750,000 expired miles.

How much you pay depends on how many miles you buy back:

  • Up to 5,000 miles: $50
  • 5,001 to 20,000 miles: $100
  • 20,001 to 35,000 miles: $150
  • 35,001 to 50,000 miles: $200
  • 50,001 to 75,000 miles: $250
  • 75,001 to 100,000 miles: $300
  • 100,001 to 150,000 miles: $400
  • 150,001 to 200,000 miles: $500
  • 200,001 to 500,000 miles: $600
  • 500,001 to 750,000 miles: $700

You pay applicable sale tax plus the reinstatement fee.

Reinstate Challenge

Option B can be the better option for reinstating your miles. You must have at least 20,000 miles to reinstate to pursue this option.

First, you pay a fixed reinstatement fee of $100 to recover your expired miles. Then, you must either complete one of these activities in the next 90 days:

Other United Miles Changes

The good news is that Unites miles no longer expire. However, United is changing their award flight pricing. Although your miles can last a lifetime, you may need more miles to book an award flight.

Below is a quick summary of some of the other United Airlines MileagePlus program changes.

No More Award Chart

Beginning November 15, 2019, United is no longer publishing its award chart for United-operated and partner airline flights. This means it will be harder to predict how many miles you will need to book an award flight. Most airlines use floating prices that reflect the current cash value of the ticket and demand for that particular route or flight.

In many cases, you can expect award flight prices to increase.

United already has floating award flight prices with their more expensive Everyday Award flight prices which only state a price cap. The Saver Award ticket is a fixed price. This award ticket type is changing to a floating rate.

As always, you will still pay government fees and taxes for each flight. On most one-way domestic flights, it’s $5.60. This is standard practice with all airlines.

No Close-In Booking Fee

One positive change starting November 15, 2019, is that all MileagePlus members no longer pay a close-in booking fee for award flights booked within 14 days of departure. This cash fee can make an award ticket feel less rewarding.

United still isn’t charging fuel charges on long-haul flights like many international airlines.

Discount CLEAR Membership

If you think TSA PreCheck and Global Entry are the only ways to avoid long airport security lines, check out CLEAR. United started offering discount or free CLEAR membership for MileagePlus members.

The standard market price is $189 per year. Your price depends on your MileagePlus loyalty status:

  • MileagePlus Premier 1K: Free
  • MileagePlus Premier Silver, Gold, or Platinum: $109 per year
  • All MileagePlus members: $119 per year

Even if you’re only a basic loyalty member, you still save $60 per year.

CLEAR is rolling out to more airports each year. You can learn more about whether TSA PreCheck, Global Entry, or CLEAR is the best way to skip airport security lines. CLEAR is separate from TSA PreCheck and Global Entry.

Your TSA PreCheck membership won’t let you access CLEAR.

Earning United Miles

Although you no longer have the pressure to earn United miles every 18 months, you can still easily earn miles to book award flights more often. These are some of the best ways to acquire United miles without flying.

United Airlines Credit Cards

The co-brand United Airlines credit cards earn United miles on every $1 spent. For instance, the United Explorer Card earns 2x miles on the purchases: United Airlines, restaurants, hotel accommodations booked directly with the hotel.

These cards also waive the United Airlines checked baggage fees. Plus, you can get United Club lounge access. Premier members can also enjoy special perks like complimentary upgrades.

Transfer Chase Ultimate Rewards

These three Chase credit cards let you transfer your Ultimate Rewards points at a 1:1 ratio to United:

The Chase Sapphire Reserve is the most rewarding of the three cards. Chase Sapphire Reserve® purchases earn up to 10x Ultimate Rewards. Cardholders can earn unlimited: 

  • 10x total points on hotels and car rentals purchases through Chase Ultimate Rewards (after the first $300 is spent on travel purchases annually)
  • 10x total points on Chase Dining purchases with Ultimate Rewards
  • 5x total points on flights when you purchase travel through Chase Ultimate Rewards (after the first $300 is spent on travel purchases annually)
  • 3x points on other travel worldwide (after the first $300 is spent on travel purchases annually)
  • 3x points on other dining at restaurants, including eligible delivery services, takeout, and dining out
  • 1x points for all remaining purchases

 You will not receive rewards points on your first $300 in annual travel purchases as the annual travel statement credit reimburses these purchases.

The Sapphire Reserve also gives you a credit for Global Entry or TSA PreCheck and Priority Pass airport lounge access.

MileagePlus Partner Purchases

You can also earn United miles by making purchases within your MileagePlus loyalty account:

  • Book United Airlines or partner airline flights
  • Hotel stays
  • Car rentals, limos, shuttles, cruises, etc.
  • Online retail shopping partners
  • Applying for loans  from financial partners
  • Purchase home services
  • Buying gift cards

The MileagePlus X mobile app can be the easiest way to find earning and redeeming opportunities.


Do United miles expire? Not anymore. However, you will still need to pay a fee to reinstate miles that expired before the expiration policy changed in late August 2019. Even though your miles don’t expire after 18 months, you should still try to redeem them as soon as possible as award flight prices may increase in the near future.
