This was a result of bidding freezes. A pilot would get hired as a 727 SO then upgrade to FO within the first year. They would have a 4 year freeze, 2 years for the SO training and 2 years for the FO training.
The reason 747 and 777 went unfilled was because of freezes mostly and not people didn't want to bid them.
