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?)
