Sacha,
A recent article stated DL will lose 7600 pilots over the next 15 years to age 65. Most guys, except you at almost 65 yourself, don't go to age 65 unless they have to. The numbers are 2000 retirements in the next 5 years, 4000 total in the next 10, and then 7600 in 15 years. Your list will lose about 150 a year for the next 10 years, and then add the young Airtran group. When one senior guy at DL retires off of a widebody, many people move up the ladder. At Southwest, he/she just moves over one seat. (not a lot of movement) I think OY6 has a lot more chances to move up the ladder than most of your pilots, and especially your newhires or bottom FOs. They will be stuck doing the same type of flying for decades. No wonder they are nervous.
Bye Bye---General Lee
