Our director of training told us "there is no specific model or magic number per plane" because the number goes up and down based on what time of year it is. Really? Is that why Spirit furloughs every September? Math would say somewhere around 13-14 pilots per plane. 400 pilots divided by 30 planes is over 13, I'm not sure how many pilots or planes are actually flying/on property. We lost another plane last week due to a big mistake, a 320 I believe.
