You might want to check out the old board for information as I remember this being discussed on there quite a bit. I am hoping to need the information myself eventually! Good luck to you and sorry I can not provide more info.
If you're wanting to go to Souhtwest,you might want to check out K&S Aviation in Phoenix. It's owned by a Southwest Pilot,trains using Southwest procedures and checklists,and usually has Southwest instructors.7k also covers hotel while training. Web site is B737-training.com. Hope that helps.
