Believe what you want. His salary is based on the highest paid positions at the 5 highest paid ALPA carriers, plus an override of 25%. A very handsome salary, to be sure, but nothing near what the LM-2 shows (I haven't been privy to his W-2). He also gets a pension for the time he serves as ALPA President to compensate him for accruing no retirement funds at his own carrier during that period of time.

The rest of his compensation as shown on the LM-2 reflects the value of his housing in DC, his transportation while there, his lodging while on the road, meal and travel expenses, etc. I believe that any pilot who spends time working for ALPA and is reimbursed for expenses receives a W-2 for those reimbursements.
