Korean Air SKYPASS miles expire 10 years after you earn them, with no way to extend the miles.
Due to COVID-19, miles expiring at the end of 2021 will be extended until the end of 2022.
However, you should use your Korean SKYPASS miles before April 2023, when Korean will revamp their mileage program, and your miles will be less valuable.
