How does Alaska decide who gets upgraded?

In Alaska, passenger upgrades are typically based on a combination of factors, such as frequent flier status, fare class, and check-in time. Elite members and those with higher-priced tickets generally receive priority for available upgrades on oversold flights or when better seats become available.
