Thank you for the good info guys.I understand I should stay away from CRJs & 145 ORD & DFW will offer most flying & 145 LGA will be shortest reserve.
Follow up questions;
Keeping in mind that I will start training end of Jan meaning I hit the line in 7-9 weeks after that;
How long can I expect to sit reserve if I chose 145ORD or 145DFW ?
Also if the 145LGA is a shorter reserve ( any guesses on how much will that be ) will I be able to fly more by picking up some flying on my day offs once I can hold line ?
