Southwest has two status tiers and a third thing that is not status at all. A-List takes 20 qualifying flights or 35,000 tier qualifying points; A-List Preferred takes 40 or 70,000. The Companion Pass takes 100 qualifying flights or 135,000 Companion Pass qualifying points — and those are a separate currency from tier qualifying points, not the same number counted twice.
A-List earns 25% more points and one free checked bag, with a second at $35. A-List Preferred earns 100% more and two free bags.
Cards contribute tier qualifying points at three different rates by card — 1,500, 2,000 or 2,500 per $5,000 spent — and separately grant 10,000 Companion Pass qualifying points a calendar year.
Status earned in a calendar year is held for the remainder of that year and all of the next, and must be re-qualified each year. Rapid Rewards points do not expire, though they are forfeited if the account is closed.
Southwest prices awards against the cash fare and publishes no award chart.
