I re-ran the the #'s (messed them up the first time, whoops!). Assuming you get min RSV guarantee, the current APC upgrade times hold, and you take the first upgrade available, it would take a 10 year XJT CA ___ years to break even @ the following carriers:

• Spirit = 11 years
• UPS = 2 years*
• Delta = 7 years (5 years NB FO average, then go to WB FO average)
• Southwest = 4 years*
• United = 15 years (5 years NB FO, 5 years 75/76 FO, 5 years WB FO)
