I got a call from SWA Pilot Hiring today. I was told there are 300+ in the pool, there is one class in July and will be three in August. I interviewed with the type in May and met the June DB. She said I can expect a class in December or beginning '08.
Not sure who would have the better info, Pilot Hiring or the Training Center, but there appears to be a disconnect between them regarding the number of classes in August.
