Well I hope that most regional FO's don't have to stay in the right seat for 6-7 years as the data suggests, but it is a very real possibility. The data is a forecast based on a snapshot of the industry today. An economic change could move the numbers in either direction.
When I made my move to the regionals, I looked for the place I could be comfy with. I had friends who jumped at another airline because it offered a quick upgrade, and now their names are on the furlough list.
