Smeagel,
if the average is one a week over a workforce of 300-400, than pilots stay an average of 300-400 weeks or 6-8 years. I agree that there are airlines out there where the rate is lower, but know of many companies where the rate is much higher too.
I know that several of you don't like the company (anymore), but I also know several people working there who are happy and dozens more who have been treater worse at other companies.
Erik.
