If you collect miles with Alaska Airlines’ loyalty program, Alaska Mileage Plan, you already know how valuable they can be—especially for premium international flights on partner airlines. But like most rewards currencies, miles can expire if your account remains inactive.
This in-depth guide explains exactly how to keep your Alaska miles alive, with practical strategies, expert tips, and step-by-step instructions you can use immediately.
Understanding Alaska Mileage Expiration Rules
Before you try to prevent expiration, it’s essential to understand the policy.
Do Alaska Miles Expire?
Yes—but only under specific conditions.
- Alaska Mileage Plan miles expire after 24 months of inactivity
- “Inactivity” means no earning or redeeming activity
- Any qualifying activity resets the clock for another 24 months
Key takeaway: You don’t need to use all your miles—you just need some activity.
What Counts as Qualifying Activity?
To keep your miles from expiring, you need at least one qualifying action.
Activities That Keep Miles Active
- Earning miles from flights
- Redeeming miles for flights or upgrades
- Using a co-branded credit card
- Shopping via Alaska’s online portal
- Dining program participation
- Buying or gifting miles
Activities That Do NOT Count
- Transferring miles between accounts (in some cases)
- Viewing your account
- Expired or reversed transactions
12 Proven Ways to Stop Alaska Miles from Expiring
Here are the most effective strategies, ranked from easiest to most valuable.
1. Take a Flight with Alaska or Partners
Flying is the most straightforward method.
Steps:
- Book a flight with Alaska or partner airlines
- Enter your Mileage Plan number
- Complete the flight
Even a short, inexpensive flight resets your expiration.
2. Use an Alaska Airlines Credit Card
Co-branded cards offer effortless activity.
Benefits:
- Earn miles on everyday spending
- Automatic account activity
- Often includes welcome bonuses
Even a small purchase (₹100 or $1) can reset your expiration.
3. Shop Through the Mileage Plan Shopping Portal
One of the easiest “set and forget” methods.
How it works:
- Visit the Alaska Mileage Plan shopping portal
- Click through to a retailer
- Make a purchase
Popular retailers often include global brands like:
- Apple
- Nike
- Walmart
4. Join the Mileage Plan Dining Program
Earn miles just by eating out.
Steps:
- Register your debit/credit card

- Earn miles automatically
This is ideal if you dine out regularly.
5. Redeem a Small Number of Miles
You don’t need a full redemption.
Examples:
- Magazine subscriptions
- Small discounts
- Partial award bookings
Even redeeming 1,000 miles resets your account.
6. Buy or Gift Miles
This is a quick but less cost-effective option.
When to use:
- If your miles are about to expire
- You have no other activity options
Not ideal for long-term strategy due to cost.
7. Transfer Points from Partners
Alaska partners with several programs.
Example:
- Transfer hotel points (like Marriott Bonvoy)
Always check transfer ratios before proceeding.
8. Book Award Travel (Even for Later)
You can book travel months in advance.
- Booking counts as activity
- Travel date doesn’t matter for expiration
9. Use Alaska’s Subscription or Promotions
Occasionally, Alaska runs:
- Mileage subscription programs
- Bonus earning promotions
These count as account activity.
10. Donate Miles to Charity
Alaska allows mileage donations.
Benefits:
- Keeps miles active
- Supports good causes
11. Car Rentals and Hotel Stays
Earn miles through travel partners.
Partners include:
- Major hotel chains

12. Set Up Automatic Activity (Best Strategy)
The smartest approach is automation.
Example setup:

- Make 1 small shopping portal purchase annually

A small action saved thousands of miles.
