Nah they didnt get preference in seniority. They are all a tad senior to me and I'm a captain. Many guys didnt have the time to qualify for upgrade, so they went really junior.... all the way down into the 1000's right out of new hire class. Hence why all the nwa guys got captain slots if they wanted one.
I flew with MSP FO's some on reserve.. though this is my last week of reserve duty.. got a line next month.. and 12 days off at that.... woo!!!
