You have to remain feeder qualified for 3 years. Not stay in feeders for 3 years. You can bid package car jobs. The only difference is that if there is an open feeder job that no one else wants, and you are the junior feeder driver, you are forced to take that job.
Most supplements require a percentage of package car drivers to be feeder qualified anyway for coverage. I know all about classification and package drivers getting first bids on package car jobs, but if the right scenario happened, a feeder driver can bid a package car job even within the first 3 years.
