Moonshot,
I don't understand your numbers, sorry. A buddy at Delta tells me that there are less than 100 guys over the age of 50. That means you have a built in demographic that is in essence a youth barrier that will be impossible to ever get past.
As stated in my first post, I don't believe that is right. If A-380's were purchased someday, someone like me could NEVER hold the airplane because my growth in seniority would be stunted by the youth barrier. This would be the case for all NWA pilots due to the Delta demographic. If so many of your 50 somethings hadn't taken the lump sum and retired early, I believe this list would be done already because the age distortion would not exist. This singular issue makes the DAL/NWA SLI a very challenging one indeed.
