You should always sign up for airline frequent flyer programs. First of all, it’s free. In addition, having your information on file with the airline saves time when making a reservation. You can also put your Known Traveler Number (KTN) into your profile if you have enrolled for TSA Pre✓® or Global Entry, which you should do if you travel even somewhat regularly.
Here are links to the major US airlines’ loyalty programs, along with how long the miles you earn are good for. Note that while many plans will claim your miles will “never expire,” they will deactivate your account, thereby causing you to lose any miles earned if you don’t have a qualifying activity within a certain time frame.
ALASKA AIRLINES – Mileage Plan
https://www.alaskaair.com/content/mileage-plan.aspx
To keep your account active, you need to have activity in it every 2 years, either by earning or redeeming miles. With no activity, your account will be locked, and you have to contact Alaska Mileage Plan to reactivate it.
Mileage Plan miles do not have an expiration date and may remain in an active account indefinitely, provided that the Mileage Plan program has not been terminated pursuant to these conditions of membership. Activity in an account includes redeeming a Mileage Plan award or accruing mileage in the Alaska Airlines Mileage Plan program.
For account security purposes, we will continue to lock accounts that have been inactive for more than 2 years. If your account has been locked due to inactivity, call Guest Care to verify your identity, and they’ll reactivate the account for you. All miles in the account will still be there for you to use.
ALLEGIANT AIR – Allways Rewards
https://www.allegiantair.com/rewards-faqs
While Allegiant’s previous program didn’t award points for flying on the airline, the new Allways program works like most other loyalty programs. You’ll earn points based on how much you spend on your ticket or travel package.
Points expire after 24 months of inactivity. Activity is defined by making a booking while being logged in to your Allways account, or booking over the phone with your Allways ID Number.
If you are an active Allegiant credit cardholder, your points will not expire as long as your card account is open. For more information on the Allegiant credit card, click here.
However, all accrued points in a member’s account will be forfeited if the member’s Allways account is closed for any reason.
AMERICAN AIRLINES – AAdvantage
https://www.aa.com/loyalty/enrollment/enroll?anchorLocation=DirectURL&title=enroll
To keep your Aadvantage miles active, you need to earn or redeem miles at least once every 24 months.
Effective March 1, 2022, AAdvantage® members must have Qualifying Activity once every 24 months, or be the primary holder of an open AAdvantage® credit card account associated to their AAdvantage® account, in order to retain their miles. “Qualifying Activity” is defined as redeeming any AAdvantage® award or accruing mileage credit on any eligible American, or AAdvantage® airline participant, as well as accruing mileage credit with participating hotels, car rental companies, credit cards, and other service providers offering AAdvantage® mileage credit
DELTA AIRLINES – SkyMiles
https://www.delta.com/profile/enrolllanding.action
Delta SkyMiles don’t expire and Delta doesn’t require any activity in your account to keep miles active. Here are the only restrictions listed on their website (this is a very customer-friendly policy compared to most other airlines).
Under the SkyMiles Mileage Expiration policy, miles do not expire. Delta reserves the right to deactivate or close an account (and accordingly remove all miles in the account) under the following circumstances:
-
Fraudulent activity occurs.
-
A Member requests an account closure.
-
A Member is deceased.
-
A Member does not respond to repeated communication attempts regarding the status of his/her account.
-
A Member creates additional accounts under his/her name.
-
A Member resides in or relocates to a country where membership is prohibited under applicable law.
-
A Member violates the terms of this Membership Guide and Program Rules or any terms and conditions of a SkyMiles partner offer or other program.
FRONTIER AIRLINES – FRONTIER Miles
https://booking.flyfrontier.com/Member/Register
In order to keep your Frontier Miles active, you need to earn miles every twelve months. According to the airline, this is easy to do…..just get their credit card, and your miles will never expire.
Miles in a Member’s account do not expire so long as the Member generates accrual activity every twelve months; this includes any purchase activity on the Frontier Airlines World Mastercard. Unredeemed mileage accumulated in your account will expire at the end of the twelve-month period after your last accrual activity date. Other account activity, such as redeeming or other miscellaneous adjustments, will not extend your expiration date.
HAWAIIAN AIRLINES – HawaiianMiles
https://www.hawaiianairlines.com/my-account/join-hawaiianmiles
As of April 12, 2021, HawaiianMiles never expire.
Effective April 12, 2021 miles accrued by members do not expire. Should a member close their HawaiianMiles account, the miles in the account will be terminated.
JETBLUE AIRWAYS – TrueBlue
https://trueblue.jetblue.com/web/trueblue/register
You don’t require any account activity to keep your TrueBlue points active. These are the only requirements on the JetBlue website:
TrueBlue Points do not expire. Should a Member close his or her TrueBlue account, the Points in that account will be terminated. As set forth in these Program Rules, JetBlue has the right to cancel all or some of the Points in a TrueBlue Member’s Account should JetBlue determine, in its sole discretion, that the Member has violated these Rules or otherwise engaged in fraud, misrepresentation, abuse or other improper conduct.
SOUTHWEST AIRLINES – Rapid Rewards®
https://www.southwest.com/flight/account/enroll/enroll-member
Southwest points never expire.
Points do not expire. Should a Member close its account, the points in the account will be terminated.
SPIRIT AIRLINES – Free Spirit
https://www.spirit.com/FreeSpiritEnrollment.aspx
Can I mention I think that this is probably the only time “Free” and “Spirit” are used in the same sentence about the airline?
You’ll need to earn or redeem points once every 12 months to keep your account active.
Points don’t expire as long as you continue to earn or redeem with Spirit® or with Free Spirit® partners within a 12-month period, or if you have an open Free Spirit Credit Card account.
SUN COUNTRY AIRLINES – Sun Country Rewards
https://www.suncountry.com/(nav:login)?tab=register
Regardless of account activity, points expire 36 months after the date earned.
Sun Country Rewards points expire 36 months after the date earned
UNITED AIRLINES – MileagePlus
https://www.united.com/ual/en/us/account/enroll/default
United miles no longer expire.
Mileage accrued in a Member’s account shall be maintained in the account until it is redeemed for an award or until it is otherwise forfeited pursuant to (a) these Rules, United’s Contract of Carriage or United’s fare rules, (b) Prohibited Conduct, (c) applicable laws or regulations, (d) Member requested account closure, (e) the death of a Member or (f) the failure of a Member to respond to repeated communication attempts regarding the status of his/her account.
FINAL THOUGHTS
If you’re new to the world of frequent flyer programs, I would suggest signing up for an account with all the airlines you usually travel with. It won’t cost you anything to have an account, and it can help you accumulate rewards faster. This is also a good time to get started with a program, such as AwardWallet, to keep all of your account information together in one place.
Over the past few years, many airlines have done away with mileage expiration. The ones that do have expiration policies have loosened the restrictions for keeping miles active. With almost every program, if you’re not taking a flight, you could earn points with a dining program, shopping portal or even by buying points (only as a last resort and/or if you’ll be losing a large number of points). I try never to let points expire if I can help it.
