So I did some digging and Spirit has 4 like 4 sims and a 2 month course while Frontier has 8 sims and around a 3 month course.

From reading on here memorize the limitations, memory items, & flows in advance, use A320guide.com and 1step.com, trust the A320 system, etc...Is there a degree of on the job training after the Spirit 2 month course since that seems to be a bit shorter than the other courses? Also, I'm leaving the military so while I've not been flying a desk I'm going to be new to the world of the airlines so would there be any other general knowledge and/or technical areas I should study in advance?
