Sold out is just that...no more seats on the plane. I do not think they use they term "sold out" on say WGA fares when Anytime and BS fares are still available.
I just looked at a few dates. I found some flights with "Sold Out" across all fares. Some with "Unavailable" across all fares. Some with "Unavailiable" for WGA only. I found a few with WGA "Sold Out" and AT AND BS fares posted and one with BS "Sold Out", WGA "Unavailible" but AT fates available.
Someone posted a while ago that "Unavailible" may mean that some seats are being with held for Southwest Vacations and it was sometimes possible to purchase them through Southwest Vacations.
