Here is what I tabulated based on what information I could scrounge. Airlines Included are Fed Ex, UPS, Delta, AA, US Air East and West, Alaska, Continental, United, Southwest, Air Tran, PinnaColAba, Skywest.
I solicited, but could not get data for other non-legacy retirements. I know that those retirements won't be as much as the legacies, but in total they could add up. So if anyone has information on that....
