Detroit had 900 captain TDY's come from them 4 out of the last 5 months. This month there are non. Which explains the extra block hours. From August till now the block hours have been reduced. And if you compare all lines in Detroit and Minnie from a year ago you can plainly see a drastic reduction in Endeavor flying out of theses hubs. Heck there hasn't been a primary or secondary vacancy awarded for 900 CA since 16-02. And many people have left for either other airlines or changed bases. Just look at 16-06 for example and you'll notice Detroit 900 CA shrunk by 10 again. All I'm saying is it would be nice if they'd communicate how much smaller they plan on making it. And to say they don't know is BS.
