G J would never waste money paying for a monkey when it can put a pilot in there at half the cost. Monkeys require government inspections and compliance with ethical treatment of animals; pilots, not so much. When the monkey is sick he can't fly, the G J pilot had better work in spite of his serious illness or he will be fired. Monkey food is expensive, pilots will fly for peanuts or have to buy their own food. With monkeys G J has to pay the entire cost of health care; the pilot will pay 5000 out of his $19000 yearly pay plus another 3000+ for deductable. The monkey won't pay for his own uniform; the G J pilot will pay most of his own. The monkey requires money for housing; the G J pilot will get a second job or borrow from his family to subsidize his housing cost. The costs for the monkey are there even if snow cancels a couple days of flying; the G J pilot works without cancelation pay. The G J pilot will pay 300 a year for his family to sit standby for 3 days trying to get on a flight. The monkey requires less retraining than the G J pilot.
