The numbers on the Flight Service website are accurate. However, if you will note the number of retirements is less than half the total attrition. The total attritition includes quit, died, retired, and got fired.
One of the reasons that your seniority number didn't drop that much is that quite a few of the retirements were former TW flight attendants who were forced by the company to come back and endure the 5 weeks of training in order to get 1 day on the payroll and be eligible to retire. I might add, this was at the company's expense--hotel and meals--during the training. They could have given those people a 1 day office assignment, or a paid"report for recall" meeting, and saved a lot of money.”
