No need to argue.. Simply go to aapilots.com (not sure if USAirways guys have access) click on personal & profile (left side) than click on seniority calculator (under helpful links, right side)... It will pull up your seniority number at age 65. You can also view age per fleet...USAirways does have some younger FOs so depending on your age there will be a slight difference...

Currently AA has 59 FOs younger than 35 yrs old system wide.
