I only flew about 400 hours last year and, by the way, upgrade time is NOT 4 years. Upgrade time right now is roughly 2.5 years give or take a month. Also, I heard we will be over 31 Challenger 300's by years end; there are 21 right now so, if you do the math, that's a need for an additional 25 Captains and over 30 F/O's just in that fleet and, that doesn't include normal attrition. So figure, that's at least 55 spots of movement just for that fleet. The figure is more like just over a 100 with the lear fleets so, if you're within say 75 numbers of being captain, you roughly have a year and a few months left to upgrade.
