How are airline pensions structured: Airline companies generally have single-employer plans. However, there are often several different plans. For example, flight attendants might have one plan, while pilots might have another. Also, these plans typically are Defined Benefit Plans.
If you work for one of the old-line companies, chances are you're a member of a union which negotiates and plays a large role in administering your pension plan. Company and union officials usually form a combined board which administers and controls the investment of pension funds.
