Yes, this is the propaganda spewed from ALPA for the last 55 plus years that I have grown up under an ALPA contract (from a family of ALPA Pilots). This was true when we had Defined Benefit Retirement plans and a large percentage of retired Military Pilots joining the profession in their 40's. it was important to reach maximum pay when you were within 5 years of mandatory retirement age of 60.
Today we don't have these retirement programs and the majority of pilots are being hired in their twenties and thirties. Different times now and we should have a different pay scheme. Don't you think a 30 year pilot should make more than a 12 year pilot? What difference does it make what size airplane you fly. The size of the airplane doesn't represent the profitability of the job your performing. As a matter of fact today, the domestic airplanes are carrying the money losing Wide Body fleet at United.
Like I have said before, we need to start thinking outside the box and don't let tradition take us down the Rabbit Hole again and again.
