Not a really scientific view but in 24 years I have averaged 2.3% seniority movement and the size of the pilot seniority list has grown an average 2.6% in those same 24 years. Fleet growth has been steady at about 1.8%. We spent a lot of years trading 110-144 seat airplanes for 160-185 seat airplanes and we added nearly 100 outsourced RJ’s in that time. Seniority movement has a rising curve that goes nearly flat after 2.5 yrs or so.
