You know I have never really been too impressed with SW, it was always the cheap prices and they are the only direct from Providence to MCO so I always use them
Also the prices tend to be on the high point when they are first released. I always just watch them and book when the flight goes down (or book whenever and then adjust when the price goes down so I always have a credit)
I love SW - not a cheap as Delta express was - but if you watch for the Dings you can get some really good deals. Used to be able to get a NS flight for less than $150 rt. The staff are sooooo friendly and with the change in bording - I have had no issues. (Knock on wood)
