Additionally, if a WGA fare says 1 seat left that is probably just at that fare and after that 1 is sold there will most likely still be WGA fares available at a slightly higher price. 1 left on Business Select fare is a different story and more likely to indicate flight is selling out. Even if it sells out there are often last minute cancellations that would allow you to add your companion to the flight within 24 hours of departure. Southwest's no fee change policy means people often make changes, freeing up seats close to departure. --TheMiddleSeat
