Yes, airline miles do expire. Airline miles could expire when a frequent flyer program account has gone unused for a certain period of time, when a set number of months have passed since the miles were earned, or when the loyalty account is closed while there are still unused miles in it. The exact expiration policy for airline miles depends on the frequent flyer program, though.
Airline Miles Expiration by Frequent Flyer Program
The best rewards programs are Delta SkyMiles for free flights, Wyndham Rewards for free hotel nights, Capital One Rewards for credit cards with a lot of cash back or miles, and apps like Swagbucks and Shopkick for online shopping rewards and discounts. There are roughly 4 billion U.S. consumers enrolled in customer rewards programs. But you can’t just join them all. It would be too difficult to manage.
The best way to check your frequent flyer miles balance is by logging in to the airline's website. The miles balance will be easily accessible from your online account.
Another way to check your mileage balance is to call your airline’s frequent flyer customer service number. You will need to provide the account number and your personal information such as your name and address.
