How do boarding groups work on Southwest Airlines?

At Southwest Airlines, the boarding group is determined based on several travel-related factors. Apart from pre-boarding, the airline has six distinct boarding zones. Additionally, passengers may be assigned Southwest boarding groups based on when they purchased their tickets and their MileagePlus status. Passengers with priority boarding board the flight first, followed by groups 1 through 8; there are also pre-boarding and final boarding groups.
