Airlines里面
American Airlines AAdvantage miles expire after 24 months of inactivity
据Google说连Alaska现在都不过期了
No, Alaska Airlines Mileage Plan miles do not expire as long as the account is active and open. However, if an account is inactive for more than two years, it may be frozen for security reasons. If this happens, you can call customer service to confirm your identity and have your account unlocked. All of your miles will still be there
