I would have to agree with this. We've been seeing fast 1 year upgrades for a while because exactly 2.5 years ago there were about 360 pilots on the list and today there are 815. The plan is to be 900 by this summer but after that the next 2 years will have very little growth and will be all about replacing the MD80's and 75's with the Airbus. Since the CBA attrition has stopped except for a little on the bottom 25% of the list. I would expect growth to pick back up again by summer of 2019 assuming we're not deep in an economic recession.
