Seniority, upgrades, exc
I appreciate all the help/answers from those of you who have been around. One question I have relates to seniority. Does seniority begin when you start day 1 with the company, and if so, is there anything that can change your seniority while still employed with the same company? Once you pick a regional, doesn't it benefit you to stay there until you move to a major if possible? For example, if a new hire FO starts in April, and then 6 months later another pilot starts but comes into the company as a "street" captain, would the new hire FO eventually be senior to the transfer once he/she upgraded (basically, wouldn't the person who transfers mid career always be junior until everyone hired before him/her caught up to them?)
