On the 145, the fleet is "fully staffed", so the movement comes from upgrades and not growth. With seasonal fleet movement between bases, it is not an easy question to answer.

As I am not on the 145, I can't give actual answers but I can give you the "worst case scenario": DFW 145 theoretical junior lineholder is a 1/2018 hire, and ORD 145 is 9/2018 hire.
