Dude...you need to chill the effff out and stop worrying about days off during training. You will get at a bare minimum one day off a week, but most likely two. Seriously though time spent in training is such an impeccably small part of the picture. I wouldn't worry abut it. And if you're still worried after reading this, then don't come to the airlines. Go get a get a nice beurocratic "gubment" job where you can chunk efficiency out the window.
